LRRTM1

LRRTM1 [ [http://www.ncbi.nlm.nih.gov/pubmed/17667961 NCBI link for LRRTM1] ] , or Leucine-rich repeat transmembrane neuronal protein 1, is the first gene linked to increased odds of being left-handed [ [http://anthropology.net/2007/08/01/lrrtm1-a-possible-gene-for-left-handedness/ LRRTM1: A possible gene for left-handedness « Anthropology.net ] ] . The researchers also claim that possessing this gene slightly raises the risk of psychotic mental illnesses such as schizophrenia [ [http://news.nationalgeographic.com/news/2007/08/070801-left-gene.html Gene for Left-Handed Trait Discovered ] ] . As the name implies, its protein product is a transmembrane protein, which contains many leucine rich repeats, that is present in neurons. It is expressed during the development of specific forebrain structures and shows a variable pattern of maternal downregulation (genomic imprinting)
