Ataxin 1Image via Wikipedia The recent SNP association report, “Identification of loci associated with schizophrenia by genomewide association and follow-up (doi:10.1038/ng.201) by O’Donovan et. al, – an analysis of more than 370,000 Affymetrix SNPs on a population of 479 affected individuals – finds strong evidence for c in the zinc finger protein 804A (ZNF804A). One clue to the otherwise inscrutable history of this gene may lie in the findings of a yeast 2-hybrid screen where ataxin-1 was used as a bait. Mutations in ATXN1 can give rise to Spinocerebellar Ataxia, a degenerative condition of the cerebellum and spinal cord. Such profound developmental deficits, even if weakly expressed would be consistent with the many cognitive difficulties experienced by patients with schizophrenia.
