Description

Not observed at significant frequency in large population cohorts (gnomAD); Missense variants in this gene are often considered pathogenic (HGMD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This substitution is predicted to be within the transmembrane segment S1 of the second homologous domain; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 24077912)
