Genes affected
TNNI3 (HGNC:11947): (troponin I3, cardiac type) Troponin I (TnI), along with troponin T (TnT) and troponin C (TnC), is one of 3 subunits that form the troponin complex of the thin filaments of striated muscle. TnI is the inhibitory subunit; blocking actin-myosin interactions and thereby mediating striated muscle relaxation. The TnI subfamily contains three genes: TnI-skeletal-fast-twitch, TnI-skeletal-slow-twitch, and TnI-cardiac. This gene encodes the TnI-cardiac protein and is exclusively expressed in cardiac muscle tissues. Mutations in this gene cause familial hypertrophic cardiomyopathy type 7 (CMH7) and familial restrictive cardiomyopathy (RCM). Troponin I is useful in making a diagnosis of heart failure, and of ischemic heart disease. An elevated level of troponin is also now used as indicator of acute myocardial injury in patients hospitalized with moderate/severe Coronavirus Disease 2019 (COVID-19). Such elevation has also been associated with higher risk of mortality in cardiovascular disease patients hospitalized due to COVID-19. [provided by RefSeq, Aug 2020]

Likely pathogenic, no assertion criteria providedclinical testingStanford Center for Inherited Cardiovascular Disease, Stanford UniversityJul 24, 2015Note this variant was found in clinical genetic testing performed by one or more labs who may also submit to ClinVar. Thus any internal case data may overlap with the internal case data of other labs. The interpretation reviewed below is that of the Stanford Center for Inherited Cardiovascular Disease. The variant has been seen in at least 11 unrelated cases of HCM (not including this patient's family). There is supporting segregation data available. We have seen this variant in one other person with HCM in our clinic. Per the LMM ClinVar summary "the Arg162Gln variant in TNNI3 has been reported in >10 individuals with HCM and segregated with disease in 11 affected family members across several families (Van Driest 2003, Doolan 2005, Mogensen 2004, Ingles 2005, Rani 2012, LMM unpublished data)." In ClinVar GeneDx notes that they have observed the variant in several unrelated individuals tested for HCM (phenotyeps not given). LMM notes "in 1 family tested at our laboratory, the variant was absent in an affected individual, raising additional concerns, although this discrepancy can have multiple explanations including the presence of more than 1 pathogenic variant or an environmental origin of disease." Other variants have been reported in association with disease at this codon (p.Arg162Pro and p. Arg162Gly) . The variant is located within a functionally significant troponin C binding site domain. In silico analysis of R162Q mutant protein demonstrated a decrease in protein stability (Ramachandran et al., 2013). There is also expertimental evidence tha tsuggests this variant dirupts protein-protein interactions. Per the LMM ClinVar submission "arginine (Arg) at position 162 is not conserved in evolutionarily distant species (two bat species, birds, and fish), supporting that a change at this position may be tolerated; however, not all pathogenic variants are conserved in lower species." The variant was reported online in 3 of 60,827 individuals in the Exome Aggregation Consortium dataset (http://exac.broadinstitute.org/), which currently includes variant calls on ~64,000 individuals of European, African, Latino and Asian descent (as of July 24, 2015). Specifically, the variant was observed in 2/33619 Europeans and 1/8314 South Asian. Another variant at the same codon, p.Arg162Trp, is present in 4 of 60,876 individuals in ExAC. The phenotype of those individuals is not publicly available. The dataset is comprised of multiple cohorts, some of which were recruited from the general population, others were enriched for common cardiovascular disease. Note that other variants with strong evidence for pathogenicity have been seen at similar frequencies in a dataset like this so this does not necessarily rule out pathogenicity (Pan et al 2012). -

Hypertrophic cardiomyopathy Pathogenic:4
Pathogenic, criteria provided, single submitterresearchAgnes Ginges Centre for Molecular Cardiology, Centenary InstituteMar 28, 2017TNNI3 Arg162Gln has been identified in multiple HCM probands (Walsh R, et al., 2017; Cecconi M, et al., 2016; Mouton JM, et al., 2015; Coppini R, et la., 2014; Kapplinger JD, et al., 2014; Rani DS, et al., 2012; Bos JM, et al., 2006; Mogensen J, et al., 2004; Van Driest SL, et al., 2003) and has been found to segregate with disease in 2 HCM families (Rani DS, et al., 2012; Mogensen J, et al., 2004). The variant is present at a low frequency in the Exome Aggregation Consortium dataset (MAF=0.00003; http://exac.broadinstitute.org/). We have identified this variant in 3 HCM probands (Burns et al., 2017), one of their families have been previously described (Ingles J, et al., 2005; Doolan A, et al., 2005). Computational tools CADD, MutationTaster, and PolyPhen-2 predict this variant to have a deleterious effect, however SIFT predicts this variant to be "tolerated". A mammalian two-hybrid system has shown that this missense change decreases troponin T and troponin C interaction (Doolan A, et al., 2005), whereas crystal structure modelling suggests that the Arg162Gln affects troponin C stability (Ramachandran G, et al., 2013). In summary, the TNNI3 Arg162Gln is a rare variant which has been described in multiple HCM probands around the world and has been found to segregate strongly in at least 2 families, therefore we classify this variant as "pathogenic". -
Likely pathogenic, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineNov 18, 2021The p.Arg162Gln variant in TNNI3 has been reported in >20 individuals with HCM, one of whom was homozygous and 3 of whom also carried other pathogenic variants in HCM-associated genes. This variant also segregated with disease in >10 affected relatives from multiple families (Van Driest 2003 PMID:12860912, Mogensen 2004 PMID:15607392, Doolan 2005 PMID:15698845, Cheng 2005 PMID:15992656, Ingles 2005 PMID:16199542, Bos 2006 PMID:16352453, Gruner 2011 PMID:21511876, Rani 2012 PMID:22876777, Kapplinger 2014 PMID:24510615, Mouton 2015 PMID:25940119, Cecconi 2016 PMID 27600940, Burns 2017 PMID 28790153, Walsh 2017 PMID 27532257, Lorenzini 2020 PMID 32731933, LMM data). However, the p.Arg162Gln variant was also present in several unaffected relatives, many of whom were older than 50, suggesting reduced penetrance or a milder role (Mogensen 2004 PMID: 15607392, LMM data). This variant did not segregate with disease in 1 affected relative, although this discrepancy may be explained by the presence of more than 1 pathogenic variant in this family or an environmental origin of disease. This variant has also been reported by other clinical laboratories in ClinVar (Variation ID 43389) and was also identified in 0.005% (6/113172) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). In vitro functional studies using a mammalian two-hybrid system suggests that this variant may impact protein function by affecting the interaction with other binding partners (troponin T and troponin C; Doolan 2005 PMID:15698845). Computational prediction tools and conservation analyses suggest that this variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. Additionally, two different variants at this position (p.Arg162Pro and p.Arg162Trp) were identified in multiple individuals with HCM (Kimura 1997 PMID:9241277, Richard 2005 PMID:12707239, Doolan 2005 PMID:15698845, Ingles 2005 PMID:16199542, Gray 2013 PMID:23270746, LMM data), suggesting that a change of this amino acid residue is not tolerated. In summary, the p.Arg162Gln variant meets criteria to be classified as likely pathogenic for autosomal dominant HCM; however, this variant may have a milder role suggested by the incomplete penetrance seen in some family members and the individuals who were homozygous or double heterozygous.

Likely pathogenic, criteria provided, single submitterclinical testingAll of Us Research Program, National Institutes of HealthSep 12, 2024This missense variant replaces arginine with glutamine at codon 162 of the TNNI3 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). A functional study has shown that this variant disrupts interactions with troponin C and T (PMID: 15698845). However, clinical relevance of this observation is not known. This variant has been reported in over ten unrelated individuals affected with hypertrophic cardiomyopathy (PMID: 12860912, 15607392, 15698845, 15992656, 16352453, 25940119, 31877599, 33029862, 3349559, Yang et al 2018). This variant has been shown to segregate with hypertrophic cardiomyopathy in a family study (PMID: 22876777). This variant has also been reported in the homozygous state in an individual affected with severe, early-onset hypertrophic cardiomyopathy (PMID: 31877599). The proband's four relatives were asymptomatic heterozygous carriers. This variant has been identified in 10/249030 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Different missense variants occurring at the same codon, p.Arg162Pro and p.Arg162Trp, are known to cause disease (Clinvar variation ID: 43390, 161396), indicating that arginine at this position is important for the protein function. Based on the available evidence, this variant is classified as Likely Pathogenic. -
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 16, 2024This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 162 of the TNNI3 protein (p.Arg162Gln). This variant is present in population databases (rs397516354, gnomAD 0.006%). This missense change has been observed in individuals with hypertrophic cardiomyopathy (PMID: 12860912, 15607392, 15698845, 15992656, 16352453, 22876777). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 43389). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. Experimental studies have shown that this missense change affects TNNI3 function (PMID: 15698845). For these reasons, this variant has been classified as Pathogenic. -

Likely pathogenic, criteria provided, single submitterclinical testingVictorian Clinical Genetics Services, Murdoch Childrens Research InstituteJun 24, 2022Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Likely pathogenic. Following criteria are met: 0103 - Gain of function and loss of function are reported mechanisms of disease in this gene. The former is associated with familial restrictive cardiomyopathy 1 (MIM#115210) and hypertrophic cardiomyopathy 7 (MIM#613690), while the latter is associated with dilated cardiomyopathy 1FF (MIM#613286) (PMID: 19914256, PMID:21533915). (I) 0108 - This gene is associated with both recessive and dominant disease. The recessive form of inheritance is the exception and has only been reported in a small number of families (PMID: 15070570, PMID:23270746). (I) 0112 - The condition associated with this gene has incomplete penetrance (PMID: 15607392). (I) 0115 - Variants in this gene are known to have variable expressivity (PMID: 23270746). (I) 0200 - Variant is predicted to result in a missense amino acid change from arginine to glutamine. (I) 0251 - This variant is heterozygous. (I) 0302 - Variant is present in gnomAD (v2) <0.001 for a dominant condition (10 heterozygotes, 0 homozygotes).

Pathogenic, criteria provided, single submitterclinical testing3billionJan 03, 2022Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000043389, PMID:12860912, PS1_S).The variant was co-segregated with Cardiomyopathy, hypertrophic, 7, associated with TNNI3 gene in multiple affected family members with additional meioses meeting strong evidence levels (PMID: 15607392, 22876777) (PP1_S). The variant has been observed in at least two similarly affected unrelated individuals (PMID: 12860912, 15607392, 16352453, PS4_M). Different missense changes at the same codon have been reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000043390,VCV000626844, PMID:9241277,12707239, PM5_M). In silico tool predictions suggest damaging effect of the variant on gene or gene product (3CNET: 0.883, PP3_P). A missense variant is a common mechanism associated with Cardiomyopathy (PP2_P). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -

Pathogenic, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpMay 22, 2023Variant summary: TNNI3 c.485G>A (p.Arg162Gln) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4e-05 in 249030 control chromosomes (gnomAD). This frequency is not significantly higher than estimated for a pathogenic variant in TNNI3 causing Hypertrophic Cardiomyopathy (4e-05 vs 0.00013), allowing no conclusion about variant significance. c.485G>A has been reported in the literature in multiple individuals affected with Hypertrophic Cardiomyopathy (examples: Bos_2006, Cheng_2005, Doolan_2005,Mogensen_2004, VanDriest_2003). These data indicate that the variant is very likely to be associated with disease. The following publications have been ascertained in the context of this evaluation (PMID: 15698845, 15607392, 12860912, 15992656, 16352453). Thirteen clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and all classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
TNNI3-related disorder Pathogenic:1
Pathogenic, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesApr 08, 2024The TNNI3 c.485G>A variant is predicted to result in the amino acid substitution p.Arg162Gln. This variant has been frequently reported and found to segregate with disease in individuals with hypertrophic cardiomyopathy (see, for example, Van Driest et al. 2003. PubMed ID: 12860912; Mogensen et al. 2004. PubMed ID: 15607392; Ingles et al. 2005. PubMed ID: 16199542; Supplementary Table 1, Coppini et al. 2014. PubMed ID: 25524337). This variant is reported in 0.0065% of alleles in individuals of South Asian descent in gnomAD. This variant is interpreted as pathogenic. -
Cardiovascular phenotype Pathogenic:1
Likely pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsAug 24, 2022The p.R162Q variant (also known as c.485G>A), located in coding exon 7 of the TNNI3 gene, results from a G to A substitution at nucleotide position 485. The arginine at codon 162 is replaced by glutamine, an amino acid with highly similar properties. This variant has been reported in multiple individuals with hypertrophic cardiomyopathy (HCM) (e.g., Van Driest SL et al. Circulation. 2003;108(4):445-51; Ingles J et al. J Med Genet. 2005;42(10):e59; Gruner C et al. Circ Cardiovasc Genet. 2011;4(3):288-95; Coppini R et al. J Am Coll Cardiol. 2014;64(24):2589-600; Lopes LR et al. Heart. 2015; 101(4):294-301; Mouton JM et al. Cardiovasc J Afr. 2015; 26(2):63-9; Walsh R et al. Genet. Med. 2017;19:192-203). This variant co-segregated with disease in three families; however, multiple unaffected family members also carried the variant (Mogensen J et al. J Am Coll Cardiol. 2004; 44(12):2315-25; Doolan A et al. J Mol Cell Cardiol. 2005; 38(2):387-93; Rani DS et al. BMC Med Genet. 2012;13:69). This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the majority of available evidence to date, this variant is likely to be pathogenic. -
