The c.386G>T (p.C129F) alteration is located in exon 1 (coding exon 1) of the KRTAP4-9 gene. This alteration results from a G to T substitution at nucleotide position 386, causing the cysteine (C) at amino acid position 129 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
