Functioni

During development, promotes the survival and differentiation of selected neuronal populations of the peripheral and central nervous systems. Participates in axonal growth, pathfinding and in the modulation of dendritic growth and morphology. Major regulator of synaptic transmission and plasticity at adult synapses in many regions of the CNS. The versatility of BDNF is emphasized by its contribution to a range of adaptive neuronal responses including long-term potentiation (LTP), long-term depression (LTD), certain forms of short-term synaptic plasticity, as well as homeostatic regulation of intrinsic neuronal excitability.1 Publication

Involvement in diseasei

Bulimia nervosa 2 (BULN2)1 Publication
Disease susceptibility is associated with variations affecting the gene represented in this entry.
Disease descriptionA psychiatric disorder characterized by eating an unusually large amount of food in a short period of time, followed by inappropriate acts (purging) to avert weight gain. Compensatory behavior includes self-induced vomiting, laxative abuse, and excessive exercise.
See also OMIM:610269
Congenital central hypoventilation syndrome (CCHS)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionRare disorder characterized by abnormal control of respiration in the absence of neuromuscular or lung disease, or an identifiable brain stem lesion. A deficiency in autonomic control of respiration results in inadequate or negligible ventilatory and arousal responses to hypercapnia and hypoxemia.
