The c.2575C>T (p.R859W) alteration is located in exon 15 (coding exon 15) of the DENND2A gene. This alteration results from a C to T substitution at nucleotide position 2575, causing the arginine (R) at amino acid position 859 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
