RCV000587919 | SCV000697605 | benign | not provided | 2017-01-09 | criteria provided, single submitter | clinical testing | Variant summary: The RYR2 c.12648G>A (p.Ala4216Ala) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. One in silico tool predicts a benign outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. This variant was found in 6/120450 control chromosomes, exclusively observed in the East Asian subpopulation at a frequency of 0.0006975 (6/8602). This frequency is about 28 times the estimated maximal expected allele frequency of a pathogenic RYR2 variant (0.000025), suggesting this is likely a benign polymorphism found primarily in the populations of East Asian origin. The variant of interest has not, to our knowledge, been reported as germline mutation in affected individuals via publications and/or reputable databases/clinical diagnostic laboratories; nor evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as benign. |
Ambry Genetics | RCV000617652 | SCV000737893 | likely benign | Cardiovascular phenotype | 2017-01-31 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: 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. |
