Zhang et al. discovered that, compared to Chinese domestic pigs and Large White pigs, the identified Neural Glycoprotein 4 X-linked (NLGN4X) and Neural Glycoprotein 4 Y-linked (NLGN4Y) in Su-Huai pigs are associated with neurological diseases and neural signal transduction. The gene discussed is NLGN4Y; the disease is nervous system disorder.
