The c.71T>C (p.V24A) alteration is located in exon 2 (coding exon 1) of the RUSC2 gene. This alteration results from a T to C substitution at nucleotide position 71, causing the valine (V) at amino acid position 24 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 24 of the RUSC2 protein (p.Val24Ala). This variant is present in population databases (rs764969982, gnomAD 0.005%). This variant has not been reported in the literature in individuals affected with RUSC2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1483782). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
