We hypothesize that accumulation of these complexes might result in pathology due to the formation of misfolded GCAP2 oligomers, in much a similar way to which synuclein, APP, Tau, Huntingtin or ataxin lead to neuronal cell death in Parkinson's (PD), Alzheimer (AD), Huntington's (HD) or spinocerebellar ataxia (SCA) diseases. This evidence concerns the gene APP and cerebellar ataxia.
