DENN domain-containing protein 5A

Gene

DENND5A

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Guanine nucleotide exchange factor (GEF) which may activate RAB6A and RAB39A and/or RAB39B. Promotes the exchange of GDP to GTP, converting inactive GDP-bound Rab proteins into their active GTP-bound form. Involved in the negative regulation of neurite outgrowth (By similarity).By similarity1 Publication

Involvement in diseasei

Epileptic encephalopathy, early infantile, 49 (EIEE49)2 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of epileptic encephalopathy, a heterogeneous group of severe childhood onset epilepsies characterized by refractory seizures, neurodevelopmental impairment, and poor prognosis. Development is normal prior to seizure onset, after which cognitive and motor delays become apparent. EIEE49 is a severe autosomal recessive form characterized by onset of seizures in the neonatal period, global developmental delay, intellectual disability, and additionally cerebral calcifications and coarse facial features.
