Neuroscience Genetic Clue to Mental Retardation

One of the receptors for angiotensin II, AGTR1, plays a key role in the regulation of blood pressure and water electrolyte balance. A second receptor, AGTR2, is expressed in a number of tissues including the brain, but its function is poorly understood. Vervoort et al. identify AGTR2 as the causative gene in a family with X-linked mental retardation and find sequence changes in the gene in several unrelated patients with the disorder. These results suggest that AGTR2 plays a role in brain development, cognitive function, or both. Further study of signaling pathway of AGTR2 may provide insight into the pathogenesis of mental retardation, which affects 2 to 3% of the population.
