Invitae RCV001362323 SCV001558334 uncertain significance not provided 2020-08-19 criteria provided, single submitter clinical testing This sequence change replaces glycine with aspartic acid at codon 159 of the COL4A5 protein (p.Gly159Asp). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and aspartic acid. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with clinical features of Alport syndrome (Invitae). 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 COL4A5 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
