Invitae RCV000534855 SCV000652077 uncertain significance Focal segmental glomerulosclerosis 5; Charcot-Marie-Tooth disease, dominant intermediate E 2019-04-08 criteria provided, single submitter clinical testing This sequence change replaces tyrosine with aspartic acid at codon 50 of the INF2 protein (p.Tyr50Asp). The tyrosine residue is highly conserved and there is a large physicochemical difference between tyrosine and aspartic acid. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individuals affected with Charcot-Marie-Tooth disease and focal segmental glomerulosclerosis (PMID: 28780565, Invitae). ClinVar contains an entry for this variant (Variation ID: 472837). 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: "Probably 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.
