The c.1301G>C (p.R434P) alteration is located in exon 1 (coding exon 1) of the KRTAP16-1 gene. This alteration results from a G to C substitution at nucleotide position 1301, causing the arginine (R) at amino acid position 434 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
