The c.176G>A (p.R59Q) alteration is located in exon 2 (coding exon 2) of the KRT222 gene. This alteration results from a G to A substitution at nucleotide position 176, causing the arginine (R) at amino acid position 59 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
