Genes affected
ANKRD1 (HGNC:15819): (ankyrin repeat domain 1) The protein encoded by this gene is localized to the nucleus of endothelial cells and is induced by IL-1 and TNF-alpha stimulation. Studies in rat cardiomyocytes suggest that this gene functions as a transcription factor. Interactions between this protein and the sarcomeric proteins myopalladin and titin suggest that it may also be involved in the myofibrillar stretch-sensor system. [provided by RefSeq, Jul 2008]

This infant with asymmetric LV hypertrophy had genetic testing for hypertrophic cardiomyopathy with the Invitae laboratory. The following genes were evaluated for sequence changes and exonic deletions/duplications: A2ML1, ABCC9, ACADVL, ACTC1, ACTN2, AGL, ALMS1, ANKRD1, BAG3, BRAF, CACNA1C, CALR3, CAV3, CBL, CHRM2, CPT2, CRYAB, CSRP3, CTF1, CTNNA3, DES, DMD, DNAJC19, DOLK, DSC2, DSG2, DSP, DTNA, ELAC2, EMD, EYA4, FHL1, FHL2, FKRP, FKTN, FLNC, GAA, GATA4, GATA6, GATAD1, GLA, HCN4, HRAS, ILK, JPH2, JUP, KRAS, LAMA4, LAMP2, LDB3, LMNA, LRRC10, MAP2K1, MAP2K2, MTO1, MYBPC3, MYH6, MYH7, MYL2, MYL3, MYLK2, MYOM1, MYOZ2, MYPN, NEBL, NEXN, NF1, NKX2-5, NPPA, NRAS, PDLIM3, PKP2, PLEKHM2, PLN, PRDM16, PRKAG2, PTPN11, RAF1, RASA1, RBM20, RIT1, RRAS, RYR2, SCN5A, SGCD, SHOC2, SLC22A5, SOS1, SOS2, SPRED1, TAZ, TCAP, TGFB3, TMEM43, TMEM70, TMPO, TNNC1, TNNI3, TNNT2, TPM1, TTN, TTR, TXNRD2, VCL The following genes were evaluated for sequence changes only: SDHA One variant was reported. p.Arg154Trp (c.460C>T) in exon 5 of the ANKRD1 gene (NM_014391.2) Chromosome location 10:92677581 G / A Based on the information reviewed below, we classify it as a Variant of Uncertain Significance (VUS), concluding that there is not sufficient evidence for its pathogenicity to warrant using it for predictive genetic testing. The ANKRD1 gene currently has no well-established disease association; however, there is preliminary evidence supporting a correlation with autosomal dominant dilated cardiomyopathy (DCM) (MedGen UID: 2880) and hypertrophic cardiomyopathy (HCM) (PMID: 19608031). This specific variant has not been reported in the literature in association with disease. This is a nonconservative amino acid change, resulting in the replacement of a positively-charged Arginine with a nonpolar Tryptophan. Arginine at this location is absolutely conserved across ~100 vertebrate species for which we have data. Nearby residues are also highly conserved. There are no Likely Pathogenic or Pathogenic variants listed in ClinVar within 10 amino acids to either side, although since this is a newly-characterized gene there are only 3 such variants listed total. According to the Invitae report, algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). It is present in gnomAD (a population database of 140,000 individuals not selected for cardiomyopathy) in 2 South Asian individuals, for an allele frequency in that ethnic group of 0.006%. Overall allele frequency among all ethnicities 0.0008%. There is also 1 non-Finnish European ancestry individual with a p.Arg154Gln variant. There is good sequencing coverage at this site. The gnomAD database includes variant calls on ~140,000 individuals of European, African, Latino, South Asian, Ashkenazi, and East Asian descent. 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. The curators made an effort to exclude individuals with severe pediatric diseases.

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 477609). This variant has not been reported in the literature in individuals affected with ANKRD1-related conditions. This variant is present in population databases (rs751739709, gnomAD 0.006%). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 154 of the ANKRD1 protein (p.Arg154Trp).

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.R154W variant (also known as c.460C>T), located in coding exon 5 of the ANKRD1 gene, results from a C to T substitution at nucleotide position 460. The arginine at codon 154 is replaced by tryptophan, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear.
