The c.317A>C (p.Q106P) alteration is located in exon 1 (coding exon 1) of the KRTAP5-6 gene. This alteration results from a A to C substitution at nucleotide position 317, causing the glutamine (Q) at amino acid position 106 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
