Genes affected

MIAT (HGNC:33425): (myocardial infarction associated transcript) This gene encodes a spliced long non-coding RNA that may constitute a component of the nuclear matrix. Altered expression of this locus has been reported to be associated with a susceptibility to myocardial infarction. It has also been proposed that pathways involving this transcript may contribute to the pathophysiology of schizophrenia. A similar gene in mouse has been associated with retinal cell fate determination. Alternatively spliced transcript variants have been identified. [provided by RefSeq, Dec 2014]
