Genes affected

IGF1R (HGNC:5465): (insulin like growth factor 1 receptor) This receptor binds insulin-like growth factor with a high affinity. It has tyrosine kinase activity. The insulin-like growth factor I receptor plays a critical role in transformation events. Cleavage of the precursor generates alpha and beta subunits. It is highly overexpressed in most malignant tissues where it functions as an anti-apoptotic agent by enhancing cell survival. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, May 2014]

IRAIN (HGNC:50365): (IGF1R antisense imprinted non-protein coding RNA) This gene expresses a long non-coding RNA in antisense to the insulin-like growth factor type I receptor (IGF1R) gene. This transcript is imprinted and expressed from the paternal allele. It interacts with chromatin and may promote long-range DNA interactions that influence the regulation of gene expression.
