The c.274C>A (p.P92T) alteration is located in exon 1 (coding exon 1) of the KRTAP4-8 gene. This alteration results from a C to A substitution at nucleotide position 274, causing the proline (P) at amino acid position 92 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
