ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV000723680 SCV000884189 likely benign not provided 2018-01-22 criteria provided, single submitter clinical testing The c.3010G>T; p.Ala1004Ser variant has been reported in at least five individuals diagnosed with dilated cardiomyopathy (Carniel 2005, Hershberger 2010, Merlo 2013), as well as one patient with arrhythmogenic right ventricular cardiomyopathy (Medeiros-Domingo 2017) and a case of familial atrial septal defects (Posch 2011). However, this variant is listed in the genome Aggregation Database (gnomAD) with a Latino population frequency of 0.2% (identified on 64 out of 34,418 chromosomes), and detailed analysis of ExAC population genetic data suggests the variant is likely to be tolerated (Nouhravesh 2016). Furthermore, this variant was found in two healthy individuals in a study of Europeans between the ages of 55-75 with no sign of cardiac abnormalities (Andreason 2013) and in 3 out of 267 healthy Spanish individuals (0.56%) (Dopazo 2016), and was also detected in healthy family members of the atrial septal defect patient (Posch 2011). It is classified in ClinVar with conflicting interpretations (ID 14151). A functional study showed that expression of this variant in myocytes led to decreased peak sarcomere shortening compared to controls (Klos 2017). Based on the available information, including its prevalence in the general population, the p.Ala1004Ser variant is likely to be benign.

GeneDx RCV000037468 SCV000513789 likely benign not specified 2017-09-08 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.
