The c.2236G>T (p.G746C) alteration is located in exon 9 (coding exon 9) of the DCAF5 gene. This alteration results from a G to T substitution at nucleotide position 2236, causing the glycine (G) at amino acid position 746 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
