The c.701G>A (p.C234Y) alteration is located in exon 2 (coding exon 1) of the KPRP gene. This alteration results from a G to A substitution at nucleotide position 701, causing the cysteine (C) at amino acid position 234 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
