The c.299C>G (p.S100C) alteration is located in exon 2 (coding exon 2) of the DENND4C gene. This alteration results from a C to G substitution at nucleotide position 299, causing the serine (S) at amino acid position 100 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
