Inborn genetic diseases Uncertain:1
The p.G380S variant (also known as c.1138G>A), located in coding exon 10 of the BSCL2 gene, results from a G to A substitution at nucleotide position 1138. The glycine at codon 380 is replaced by serine, an amino acid with similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
Charcot-Marie-Tooth disease type 2 Uncertain:1
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. 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 C0"). This variant has not been reported in the literature in individuals affected with BSCL2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with serine at codon 380 of the BSCL2 protein (p.Gly380Ser). The glycine residue is moderately conserved and there is a small physicochemical difference between glycine and serine. -
