Invitae RCV001228064 SCV001400448 uncertain significance Giant axonal neuropathy 1 2021-08-30 criteria provided, single submitter clinical testing This sequence change replaces asparagine with aspartic acid at codon 302 of the GAN protein (p.Asn302Asp). The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and aspartic acid. This variant is present in population databases (rs201937723, ExAC 0.001%). This variant has not been reported in the literature in individuals affected with GAN-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.
