GeneDx	RCV000766848	SCV000618748	uncertain significance	not provided	2017-07-06	criteria provided, single submitter	clinical testing	The R128L variant in the ADAT3 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The R128L variant is observed in 4/2452 (0.16%) alleles from individuals of non-Finnish European background in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The R128L variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position that is not conserved and in silico analysis predicts this variant likely does not alter the protein structure/function. We interpret R128L as a variant of uncertain significance.

Ambry Genetics	RCV002525157	SCV003677852	likely benign	Inborn genetic diseases	2021-06-02	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.
