NTF4 and psychotic disorder: Kranz et al. (2015) also detected a genomic variant rs746640305-A (D162Y) in the NTF4 gene in one of 48 patients with schizophrenia-related psychosis (American population); however, its functional significance was not experimentally verified. To date, there are no data on the association of certain genomic variants of NTF4 with the predisposition to mental or cognitive disorders.
