This section reviews investigations of HLA gene candidate association in schizophrenia, bipolar disorders and Autism Spectrum Disorders, focusing on the risk/protection that HLA alleles/haplotypes may confer on specific sub-groups. Influenza and other infections prenatally can also increase risk of schizophrenia and autism spectrum disorders in the offspring, suggesting that HLA/MHC genetic variations may interact with prenatal infection in the etiology of major psychiatric disorders, although complicated by the immune-suppression that occurs in pregnancy (Shah et al, 2010) . ./cache/cord-298169-2133gahl.txt ./txt/cord-298169-2133gahl.txt
