GeneDx RCV000413839 SCV000491939 uncertain significance not specified 2016-11-22 criteria provided, single submitter clinical testing The R663H variant of uncertain significance in the ABCC9 gene has not been published as a pathogenic or benign variant to our knowledge. This substitution occurs at a position that is conserved across species, and the majority of in silico tools predict R663H is probably damaging to the protein structure/function. However, the R663H variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. Furthermore, the Exome Aggregation Consortium reports R663H was observed in 0.28% of alleles from individuals of East Asian background, indicating it may be a rare benign variant in this population. Therefore, based on the currently available information, it is unclear whether this variant is pathogenic or rare benign.

Ambry Genetics RCV002418236 SCV002718421 benign Cardiovascular phenotype 2021-06-02 criteria provided, single submitter clinical testing This alteration is classified as 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.
