The c.95C>G (p.A32G) alteration is located in exon 1 (coding exon 1) of the DENND5B gene. This alteration results from a C to G substitution at nucleotide position 95, causing the alanine (A) at amino acid position 32 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
