The c.1513C>T (p.R505C) alteration is located in exon 9 (coding exon 8) of the DQX1 gene. This alteration results from a C to T substitution at nucleotide position 1513, causing the arginine (R) at amino acid position 505 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
