The c.350G>A (p.C117Y) alteration is located in exon 5 (coding exon 5) of the AOX1 gene. This alteration results from a G to A substitution at nucleotide position 350, causing the cysteine (C) at amino acid position 117 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
