The c.2462A>T (p.E821V) alteration is located in exon 17 (coding exon 15) of the DOPEY1 gene. This alteration results from a A to T substitution at nucleotide position 2462, causing the glutamic acid (E) at amino acid position 821 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
