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. This evidence concerns the gene NTF4 and schizophrenia.
