The c.418G>A (p.V140I) alteration is located in exon 1 (coding exon 1) of the KRTAP11-1 gene. This alteration results from a G to A substitution at nucleotide position 418, causing the valine (V) at amino acid position 140 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
