The c.1525C>T (p.R509C) alteration is located in exon 15 (coding exon 15) of the GFPT2 gene. This alteration results from a C to T substitution at nucleotide position 1525, causing the arginine (R) at amino acid position 509 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
