Collection Method: clinical testing

The c.1508G>A (p.R503K) alteration is located in exon 15 (coding exon 13) of the DOPEY1 gene. This alteration results from a G to A substitution at nucleotide position 1508, causing the arginine (R) at amino acid position 503 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
