What is LRRTM1 (Leucine-rich repeat transmembrane neuronal protein 1) and what does it do?
I’ll be scared if I found something like this in my exam question, but since this is the net, it gives me more opportunity to google&wiki this LRRTM1. From wikipedia: LRRTM1, or Leucine-rich repeat transmembrane neuronal protein 1, is the first gene linked to increased odds of being left-handed. The researchers also found evidence that possessing one particular variant of this gene slightly raises the risk of psychotic mental illnesses such as schizophrenia. 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). The original research article from 2007 was published in the journal Molecular Psychiatry: http://www.nature.com/mp/journal/v12/n12/abs/4002053a.html. The researchers who discovered LRRTM1’s potential involvement in left-handedness and schizophreni
