Invitae | RCV000700346 | SCV000829098 | uncertain significance | Severe myoclonic epilepsy in infancy | 2018-04-03 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine with threonine at codon 437 of the SNX27 protein (p.Arg437Thr). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and threonine. 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. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with SNX27-related disease. This variant is not present in population databases (ExAC no frequency). |
