Invitae RCV000690745 SCV000818446 uncertain significance Spinal muscular atrophy, distal, autosomal recessive, 1; Charcot-Marie-Tooth disease, axonal, type 2S 2018-05-23 criteria provided, single submitter clinical testing This sequence change replaces serine with alanine at codon 3 of the IGHMBP2 protein (p.Ser3Ala). The serine residue is weakly conserved and there is a moderate physicochemical difference between serine and alanine. 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
