The c.484G>A (p.V162I) alteration is located in exon 2 (coding exon 2) of the RDH16 gene. This alteration results from a G to A substitution at nucleotide position 484, causing the valine (V) at amino acid position 162 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
