Invitae RCV000168117 SCV000218773 uncertain significance Charcot-Marie-Tooth disease type 4 2016-09-26 criteria provided, single submitter clinical testing This sequence change replaces arginine with proline at codon 1037 of the SBF2 protein (p.Arg1037Pro). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and proline. It also falls at the last nucleotide of exon 24 of the SBF2 mRNA. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a SBF2-related disease ClinVar contains an entry for this variant (Variation ID: 188198). 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"). Algorithms developed to predict the effect of this changes on mRNA splicing suggest that this sequence change may alter mRNA splicing, but this prediction has not been confirmed by published transcriptional studies. In summary, this is a novel missense change at the end of the exon with uncertain impact on protein function and splicing. It has been classified as a Variant of Uncertain Significance.
