The c.242G>A (p.R81H) alteration is located in exon 1 (coding exon 1) of the KRTAP4-6 gene. This alteration results from a G to A substitution at nucleotide position 242, causing the arginine (R) at amino acid position 81 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
