Submissions by phenotype

not specified Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsDec 15, 2023This 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. -
