The c.1104C>G (p.I368M) alteration is located in exon 1 (coding exon 1) of the KRTAP16-1 gene. This alteration results from a C to G substitution at nucleotide position 1104, causing the isoleucine (I) at amino acid position 368 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
