Literature information of multiple sclerosis :

Pubmed ID	32924781
Year	2021
Title	Nicotinic acetylcholine receptors α7 and α9 modifies tobacco smoke risk for multiple sclerosis

Results of multiple sclerosis :

Risk Type	Disease risk
Main Result	Positive
Result	The results suggest that CHRNA7 and CHRNA9 modifies MS risk conferred by tobacco smoke, where risk among smokers was increased in carriers of the minor CHRNA9 haplotype and in non carriers the minor CHRNA7 haplotype.
Mechanism/Pathway	N/A
