The c.2759C>T (p.S920L) alteration is located in exon 16 (coding exon 16) of the DENND2A gene. This alteration results from a C to T substitution at nucleotide position 2759, causing the serine (S) at amino acid position 920 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
