Variant summary
Our verdict is Benign. Variant got -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2
The NM_003476.5(CSRP3):c.299G>A(p.Arg100His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000769 in 1,614,156 control chromosomes in the GnomAD database, including 4 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

Variant classified as Uncertain Significance - Favor Benign. The Arg100His varia nt (CSRP3) has been reported in 1 individual with HCM (Anderson 2009) and has be en detected in 1 individual with HCM tested by our laboratory who carried a path ogenic HCM variant (LMM unpublished data). This variant has been identified in 0.1% (6/7020) of European American chromosomes from a broad population by the NH LBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS; dbSNP rs13821852 3). While this frequency suggests that it is more likely benign but it is too lo w to confidently rule out a disease causing role. Additional information is need ed to fully assess its clinical significance. -

Hypertrophic cardiomyopathy 12 Uncertain:1
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
CSRP3-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
Cardiomyopathy Benign:1
- -
Dilated cardiomyopathy 1M;C2677491:Hypertrophic cardiomyopathy 12 Benign:1
- -
Cardiovascular phenotype Benign:1
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
