Tracing chromosomal aberrations in TS patients, IMMP2L has also been implicated in TS (Boghosian-Sell et al., 1996; Kroisel et al., 2001; Petek et al., 2001; Patel et al., 2011; Katuwawela, 2012) and other neurodevelopmental disorders, such as ASD, ADHD and dyslexia (Elia et al., 2010; Maestrini et al., 2010; Pagnamenta et al., 2010; Girirajan et al., 2011); yet IMMP2L coding mutations have not been identified (Petek et al., 2007). Here, IMMP2L is linked to attention deficit-hyperactivity disorder.
