The c.65G>A (p.G22D) alteration is located in exon 1 (coding exon 1) of the KRTAP25-1 gene. This alteration results from a G to A substitution at nucleotide position 65, causing the glycine (G) at amino acid position 22 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
