Expansion of a CAG repeat in the coding region of exon 1 in the ATXN2 gene located in human chromosome 12q24.1 causes the neurodegenerative disease spinocerebellar ataxia type 2 (SCA2). In contrast to other polyglutamine (polyQ) disorders, the SCA2 repeat is not highly polymorphic in central European (CEU) controls with Q22 representing 90% of alleles, and Q23 contributing between 5-7% of alleles. Recently, the ATXN2 CAG repeat has been identified as a target of adaptive selection in the CEU population. Mouse lines deficient for atxn2 develop marked hyperphagia and obesity raising the possibility that loss-of-function mutations in the ATXN2 gene may be related to energy balance in humans. Some linkage studies of obesity related phenotypes such as antipsychotic induced weight gain have reported significant lod scores on chromosome 12q24. We tested the hypothesis that rare loss-of-function ATXN2 variants cause obesity analogous to rare mutations in the leptin, leptin receptor and MC4R genes.
