Labcorp Genetics (formerly Invitae), Labcorp RCV000646779 SCV000768564 pathogenic Oculodentodigital dysplasia, autosomal recessive 2019-11-29 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt GJA1 protein function. This variant has been observed in individual(s) with oculodentodigital dysplasia (PMID: 19338053, Invitae). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (ExAC no frequency). This sequence change replaces lysine with asparagine at codon 102 of the GJA1 protein (p.Lys102Asn). The lysine residue is highly conserved and there is a moderate physicochemical difference between lysine and asparagine.
