Recent researches have implicated that mutations in the neurexin-3 (NRXN3) gene on chromosome 14q24.3-q31.1 might play a role in addiction, autism, and obesity. In order to explore the association of NRXN3 polymorphisms with schizophrenia, we examined seven single nucleotide polymorphisms (SNPs) in NRXN3 spanning 1.33 Mb of this gene, in a Chinese Han sample of 1214 schizophrenic patients and 1517 healthy control subjects. Our results showed that three SNPs were associated with schizophrenia (rs7157669: A>C, p=0.006; rs724373: C>T, p=0.014; rs7154021: C>T, p=0.018). After being corrected for multiple tests, the association of rs7157669 remained significant but those for two others were modest. According to the linkage disequilibrium pattern, the 7 SNPs may construct 3 haplotype blocks. Several haplotypes were significantly associated with schizophrenia, constructed by rs11624704-rs7157669-rs724373 (AAC, p=0.003; ACT, p=0.007, both remained significant after permutation tests), rs7154021-rs7142344 (TT, p=0.024; CT, p=0.012), respectively. Among the patients, 326 ones at first onset have received 6-week monotherapy of risperidone. Further analyses showed that two SNPs were associated with percentage of bodyweight gain following a 6-week therapy of risperidone (rs11624704: p=0.03; rs7154021: p=0.008) and rs7154021 remained significant after permutation test. Our findings suggested that NRXN3 might represent a major susceptibility gene for schizophrenia and have a role in bodyweight gain related to therapy of risperidone in Chinese Han population.

: This article discusses the relationship between disease-advocacy groups and the revision process for the Diagnostic and Statistical Manual of Mental Disorders. We discuss three examples in which patient-advocacy groups engaged with the DSM-5 revision process: Autism Speaks' worries about the contraction of the autism diagnostic category, the National Alliance on Mental Illness's support for the inclusion of psychosis risk syndrome, and B4U-ACT's critique of the expansion of pedophilia. After a descriptive examination of the cases, we address two prescriptive questions. First, what is the ethical basis for patient and advocate influence on DSM diagnoses? Second, how should the American Psychiatric Association proceed when this influence comes into conflict with other goals of the revision process? We argue that the social effects of, and values embedded in, psychiatric classification, combined with patient and advocates' experiential knowledge about those aspects of diagnosis, ethically justify advocate influence in relation to those particular matters. However, this advocate influence ought to have limits, which we briefly explore. Our discussion has implications for discussions of disease categories as loci for social movements, for analyses of the expanding range of processes and institutions that advocacy groups target, and for broader questions regarding the aims of the DSM revision process.
