The c.3263A>G (p.N1088S) alteration is located in exon 18 (coding exon 18) of the DENND5B gene. This alteration results from a A to G substitution at nucleotide position 3263, causing the asparagine (N) at amino acid position 1088 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
