The c.1622C>G (p.A541G) alteration is located in exon 15 (coding exon 13) of the DOPEY1 gene. This alteration results from a C to G substitution at nucleotide position 1622, causing the alanine (A) at amino acid position 541 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
