โฆ Synopsis
Three gene-rich loci-HS212G6, HSU93305, and HS884M20-within the short arm of the X chromosome have been examined for allelic association with schizophrenia by the transmission disequilibrium test in 70 families of male individuals affected with schizop h r e n i a . N e i t h e r t h e H S 2 1 2 G 6 n o r HS884M20 was found to be associated with schizophrenia. The HSU93305 locus, however, was significantly associated with schizophrenia (X 2 =17.92, df=3, P<0.001). The HSU93305 locus contains four distinct genes. They code, respectively, for A4 differentiation-dependent protein, triple LIM domain protein, synaptophysin, and calcium channel alpha-1 subunit. It is possible that one of these genes or some loci near to it may predispose a vulnerability to schizophrenia.

Evidence for suggestive linkage to schizophrenia with chromosome 6q markers was previously reported from a two-stage approach. Using nonparametric affected sib pairs (ASP) methods, nominal p-values of 0.00018 and 0.00095 were obtained in the screening (81 ASPs; 63 independent) and the replication (1
We completed a systematic genome-wide search for evidence of loci linked to schizophrenia using a collection of 70 pedigrees containing multiple affected individuals according to three phenotype classifications: schizophrenia only (48 pedigrees; 70 sibpairs); schizophrenia plus schizoaffective disor
## Recent reports on potential linkage by Faraone and the NIMH Genetics Initiative-Millennium Schizophrenia Consortium [1997: Am J Med Genet 74:557], and by Straub et al. [1997: Am J Med Genet 74:558], prompted us to study chromosome 10 in a sample of 72 families containing 2 or more affected sibs
