The c.1646G>C (p.R549P) alteration is located in exon 10 (coding exon 9) of the DQX1 gene. This alteration results from a G to C substitution at nucleotide position 1646, causing the arginine (R) at amino acid position 549 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
