Abstract：
:Our results seem to indicate the existence of a locus in the major histocompatibity complex (MHC) region, correlated to schizophrenic illness and strictly linked to the loci HL-A and MLR. The associations found between these last loci and the disease can probably be explained by a linkage disequilibrium or a selective pressure between the allelles of the three loci. Our results also indicate that the genetic systems investigated may be useful diagnostically as a genetic marker for schizophrenia. But the real meaning of their relationships to the illness has to be further investigated.

Epigenetic regulation lies at the heart of these interactions and mediates the lasting effects of the environment on gene regulation. An...
