New form of intellectual disability discovered
Date:4/27/2012

ts target area within the nucleus of a cell. As a result, it was unable to perform its normal role in cell division and/or RNA methylation.

Collaborators from the Wellcome Trust Centre for Stem Cell Research in Cambridge, U.K., showed which type of brain cells were likely to be most affected by this mutation. They are called Purkinje cells, a type of neuron that responds to the neurotransmitter GABA. Purkinje cells also control motor coordination, which were affected in the Pakistani family.

"We speculate that the muscle effects may result from the accumulation of the NSUN2 protein outside its target area in the nucleus," says Dr. Vincent.

To date, Dr. Vincent's lab has identified five genes causing different forms of recessive intellectual disability.
