To verify correlations between HLA and autism spectrum disorders (ASD) we studied 61 Italian families with an ASD child; results showed such correlation in 65% of cases. Case–control and TDT analysis of intrafamilial transmission of SNPs, Msats, and HLA markers surrounding the α and β blocks, indicated significant positive associations for MOGc*131 and D6S2239*105 alleles in ASD, and a negative association of MIB *332 allele in healthy siblings. Polymorphism haplotype analysis demonstrated that two haplotypes comprising the TNF-238(G)-TNF-308(G)-MIB*332-HLA-B*38-HLA-Cw*12 and the D6S265*218-HLA-A*23-MOGc*131-rs2857766(G) alleles are more frequently transmitted to ASD. MOGc and MIB loci are linked with ASD in Italian patients.
