The c.1958C>T (p.A653V) alteration is located in exon 16 (coding exon 14) of the DOPEY1 gene. This alteration results from a C to T substitution at nucleotide position 1958, causing the alanine (A) at amino acid position 653 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
