The c.3743A>G (p.N1248S) alteration is located in exon 21 (coding exon 21) of the DENND5B gene. This alteration results from a A to G substitution at nucleotide position 3743, causing the asparagine (N) at amino acid position 1248 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
