We performed a meta-analysis of the association between the functional Gln2Pro</span> polymorphism and schizophrenia using combined samples (1254 patients with schizophrenia and 1574 healthy controls) from previously published studies and our own additional samples (478 patients and 631 controls).
Our case-control study showed no significant association between the T-485 A, GC-241-240TT, Gln2Pro, and G620A (Arg211Gln) variants and schizophrenia and clinical characteristics.
A case-control association study between two polymorphisms of the SIGMAR1 gene, G-241T/C-240T and Gln2Pro, and schizophrenia in Japanese population, and meta-analysis including present and previous studies.
