The c.62G>A (p.C21Y) alteration is located in exon 1 (coding exon 1) of the KRTAP5-5 gene. This alteration results from a G to A substitution at nucleotide position 62, causing the cysteine (C) at amino acid position 21 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
