The c.279C>G (p.S93R) alteration is located in exon 1 (coding exon 1) of the KRTAP4-3 gene. This alteration results from a C to G substitution at nucleotide position 279, causing the serine (S) at amino acid position 93 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
