Autosomal recessive spinocerebellar ataxia 12;C3463992:Developmental and epileptic encephalopathy, 1 Uncertain:1
This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 380 of the WWOX protein (p.Cys380Tyr). This variant is present in population databases (rs758746365, gnomAD 0.005%). This variant has not been reported in the literature in individuals affected with WWOX-related conditions. ClinVar contains an entry for this variant (Variation ID: 546347). 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: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available"). 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. -
Inborn genetic diseases Uncertain:1
The c.1139G>A (p.C380Y) alteration is located in exon 9 (coding exon 9) of the WWOX gene. This alteration results from a G to A substitution at nucleotide position 1139, causing the cysteine (C) at amino acid position 380 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
not provided Uncertain:1
A variant of uncertain significance has been identified in the WWOX gene. The C380Y variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to ourknowledge. This variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016). The C380Y variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. However, in-silico analyses, including protein predictors and evolutionary conservation, support thatthis variant does not alter protein structure/function. Therefore, based on the currently availableinformation, it is unclear whether this variant is a pathogenic variant or a rare benign variant. -
