The c.2047G>A (p.V683I) alteration is located in exon 1 (coding exon 1) of the AP5B1 gene. This alteration results from a G to A substitution at nucleotide position 2047, causing the valine (V) at amino acid position 683 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
