Here, based on our previous NFE2L2 haplotype associations with PD in the Swedish Gothenburg (PD-Goth) discovery material, seven NFE2L2 haplotypes and one individual SNP were investigated for associations with risk and/or AAO of idiopathic PD in meta-analyses including five independent patient-control replication materials. The gene discussed is NFE2L2; the disease is Parkinson disease.
