The c.4597G>A (p.V1533I) alteration is located in exon 20 (coding exon 20) of the RGPD8 gene. This alteration results from a G to A substitution at nucleotide position 4597, causing the valine (V) at amino acid position 1533 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
