The c.286G>A (p.G96S) alteration is located in exon 1 (coding exon 1) of the KRTAP13-4 gene. This alteration results from a G to A substitution at nucleotide position 286, causing the glycine (G) at amino acid position 96 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
