The c.1547G>T (p.C516F) alteration is located in exon 9 (coding exon 8) of the GSTCD gene. This alteration results from a G to T substitution at nucleotide position 1547, causing the cysteine (C) at amino acid position 516 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
