The c.3986C>T (p.S1329L) alteration is located in exon 24 (coding exon 23) of the DENND4B gene. This alteration results from a C to T substitution at nucleotide position 3986, causing the serine (S) at amino acid position 1329 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
