a nonsignificant trendP = 0.06
Other than a nonsignificant trend toward an association between H1v and a lower risk of PSP (OR = 0.44, P = 0.06), the H1b, H1r, and H1v haplotypes have not been associated with other neurodegenerative disorders with a similar clinical or neuropathological phenotype to PD, such as PSP, MSA, or DLB. 12 , 13 , 28 Though it will be important to validate the findings of our study, future studies examination associations of H1 subhaplotypes with clinical features of other neurodegenerative diseases will also be important.
