Invitae RCV000694338 SCV000822778 uncertain significance Spinal muscular atrophy, distal, autosomal recessive, 1; Charcot-Marie-Tooth disease, axonal, type 2S 2018-04-12 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid with tyrosine at codon 22 of the IGHMBP2 protein (p.Asp22Tyr). The aspartic acid residue is weakly conserved and there is a large physicochemical difference between aspartic acid and tyrosine. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant has not been reported in the literature in individuals with IGHMBP2-related disease. 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"). 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.
