Description

Has not been previously published as pathogenic or benign to our knowledge; Not observed in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Reported in ClinVar but additional evidence is not available (ClinVar Variant ID# 405257; Landrum et al., 2016)
