Invitae RCV000642634 SCV000764321 uncertain significance Autosomal recessive distal spinal muscular atrophy 1; Charcot-Marie-Tooth disease axonal type 2S 2021-10-14 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid with lysine at codon 20 of the IGHMBP2 protein (p.Glu20Lys). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and lysine. The frequency data for this variant in the population databases is not available, as this variant may be reported as separate entries in the ExAC database. This variant has not been reported in the literature in individuals affected with IGHMBP2-related conditions. ClinVar contains an entry for this variant (Variation ID: 534930). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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.
