Invitae | RCV001036251 | SCV001199603 | uncertain significance | Severe myoclonic epilepsy in infancy | 2021-07-09 | criteria provided, single submitter | clinical testing | 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: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C15"). 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. This variant has not been reported in the literature in individuals with SNX27-related conditions. This sequence change replaces phenylalanine with tyrosine at codon 211 of the SNX27 protein (p.Phe211Tyr). The phenylalanine residue is highly conserved and there is a small physicochemical difference between phenylalanine and tyrosine. This variant is not present in population databases (ExAC no frequency). |
