The c.451C>T (p.P151S) alteration is located in exon 5 (coding exon 5) of the KRTCAP2 gene. This alteration results from a C to T substitution at nucleotide position 451, causing the proline (P) at amino acid position 151 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
