Partial deletion of GLRB and GRIA2 in a patient with intellectual disability.

ABSTRACT: We report about the partial de novo loss of GLRB and GRIA2 in an individual with intellectual disability (ID). No additional mutations were found in either gene. GLRB itself does not seem to be a good candidate as it causes autosomal recessive hyperekplexia and no symptoms were found in the patient. Mutations of GRIA2 have not been described as cause of ID to date. Nonetheless, it is a very attractive candidate because it encodes a subunit of a glutamate receptor, which is highly expressed in postsynaptic structures and has an important role in signal transduction across synapses. Although we were able to isolate a fragment of a fusion transcript of both genes from the patient's blood, we were not able to isolate a transcript with an open reading frame throughout the entire length.
