Genes affected

DENND1C (HGNC:26225): (DENN domain containing 1C) The protein encoded by this gene functions as a guanine nucleotide exchange factor for the early endosomal small GTPase RAB35, which regulates endosomal membrane trafficking and is involved in actin polymerization. The encoded protein activates RAB35 by promoting the exchange of RAB35-bound GDP for GTP. This gene may play a role in linking RAB35 activation with the clathrin machinery.

The c.2119C>A (p.P707T) alteration is located in exon 23 (coding exon 23) of the DENND1C gene. This alteration results from a C to A substitution at nucleotide position 2119, causing the proline (P) at amino acid position 707 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
