SLITRK1 ("SLIT and NTRK-like family, member 1") is a human gene that codes for a transmembrane signalling protein that is part of the SLITRK gene family, which is responsible for synapse regulation and presynaptic differentiation in the brain. Expression of the gene has been linked to early formation of excitatory synapses through binding with receptor tyrosine phosphatase PTP (LAR-RPTP). Various studies over the years have linked mutations in the gene to conditions on the OCD spectrum, Tourette syndrome and trichotillomania, however the mutations in the genome itself vary greatly between indi
