The c.802G>A (p.V268M) alteration is located in exon 6 (coding exon 6) of the IL20RB gene. This alteration results from a G to A substitution at nucleotide position 802, causing the valine (V) at amino acid position 268 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
