MYO18B and schizophrenia: Myosin-18B was reported to be associated with schizophrenia (Takata et al., 2013) and mathematical ability (Ludwig et al., 2013), as single-nucleotide polymorphisms in myosin-18B were found to be linked to depth of intraparietal sulcus in the brain, which is responsible for mathematical abilities (Ludwig et al., 2013).
