Based on a study of 790 individuals from 245 nuclear families (220 families were European Caucasian; 300 of the probands had a diagosis of schizophrenia), the rs2070106(G) allele was overtransmitted to affected offspring.[PMID 18496213]
This actually conflicts with a previous report [PMID 16389193] in which the rs2070106(A) allele was identified (also in Caucasians) in a combined gene association/expression study as associated with schizophrenia.
This is either a case of the "flip-flop" phenomenon [PMID 17273975] in which multilocus effects and variation in interlocus correlations reverse a previously reported association, or perhaps more likely, a false positive.
