TTC19 and Cognitive impairment: The patient here described presented extrapyramidal and cerebellar signs associated with cognitive impairment, symptoms described in other infantile TTC19 patients (Ghezzi et al., 2011; Atwal, 2013), but not the clear psychiatric involvement seen in TTC19 late-onset patients (Ghezzi et al., 2011; Nogueira et al., 2013) although behavioral and sleep abnormalities have been reported in our case.
