| Invitae | RCV001049214 | SCV001213255 | uncertain significance | Spinal muscular atrophy, distal, autosomal recessive, 1; Charcot-Marie-Tooth disease, axonal, type 2S | 2019-12-20 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine with tyrosine at codon 511 of the IGHMBP2 protein (p.Asn511Tyr). The asparagine residue is highly conserved and there is a large physicochemical difference between asparagine and tyrosine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with IGHMBP2-related conditions (Invitae). 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"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. 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. |
