Ambry Genetics	RCV002431471	SCV002729238	likely benign	Cardiovascular phenotype	2023-11-16	criteria provided, single submitter	clinical testing	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.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV003403197	SCV004122805	likely benign	not specified	2023-10-12	criteria provided, single submitter	clinical testing	Variant summary: FLNC c.1081C>T (p.Arg361Cys) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00016 in 249556 control chromosomes. The observed variant frequency is approximately 21 fold of the estimated maximal expected allele frequency for a pathogenic variant in FLNC causing Dilated Cardiomyopathy phenotype (7.8e-06), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.1081C>T in individuals affected with Dilated Cardiomyopathy and no experimental evidence demonstrating its impact on protein function have been reported. Five submitters have cited clinical-significance assessments for this variant to ClinVar after 2014 and classified as benign/likely benign (n=2) and VUS (n=3). Based on the evidence outlined above, the variant was classified as likely benign.
