The c.3152C>G (p.A1051G) alteration is located in exon 17 (coding exon 17) of the DENND5B gene. This alteration results from a C to G substitution at nucleotide position 3152, causing the alanine (A) at amino acid position 1051 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
