Genes affected

DENND1A (HGNC:29324): (DENN domain containing 1A) Clathrin (see MIM 118955)-mediated endocytosis is a major mechanism for internalization of proteins and lipids. Members of the connecdenn family, such as DENND1A, function as guanine nucleotide exchange factors (GEFs) for the early endosomal small GTPase RAB35 (MIM 604199) and bind to clathrin and clathrin adaptor protein-2 (AP2; see MIM 601024). Thus, connecdenns link RAB35 activation with the clathrin machinery (Marat and McPherson, 2010 [PubMed 20154091]).[supplied by OMIM, Nov 2010]

Feb 07, 2023

The c.2401C>T (p.R801C) alteration is located in exon 22 (coding exon 22) of the DENND1A gene. This alteration results from a C to T substitution at nucleotide position 2401, causing the arginine (R) at amino acid position 801 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
