The c.2536A>G (p.N846D) alteration is located in exon 9 (coding exon 9) of the DCAF5 gene. This alteration results from a A to G substitution at nucleotide position 2536, causing the asparagine (N) at amino acid position 846 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
