Invitae | RCV001318643 | SCV001509355 | uncertain significance | Giant axonal neuropathy 1 | 2021-08-28 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine with asparagine at codon 553 of the GAN protein (p.Thr553Asn). The threonine residue is moderately conserved and there is a small physicochemical difference between threonine and asparagine. This variant is present in population databases (rs759200321, 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. |
