Recently, it has been reported that carriers of a hemizygous chromosome 22q11.2 deletion may be at increased risk of early-onset Parkinson's disease. Herein, we propose a hypothesis that it is not the microdeletion per se that is responsible for the phenotype but rather a complete loss of function of a gene within the region due to the combination of the deletion and another mutation on the alternate allele. Thus we propose the deletion may be highlighting a novel locus for a recessive form of early-onset Parkinson's disease.
