Data on genotype frequency for SNPs associated to age of smoking onset and successful smoking cessation treatment

Abstract

This article contains data on the allele and genotype frequency for single nucleotide polymorphisms (SNPs) in candidate genes CHRNA5 (rs16969968, rs17408276, rs680244) CHRNA3 (rs6495307, rs12914385) NRXN1 (rs10865246, rs1882296, rs985919) and HTR2A (rs6311, rs6313) previously evaluated as genetic risk variants for cigarette smoking at an early age and relapse to smoking cessation treatment Pérez-Rubio et al., 2018. These SNPs were selected due to previous associations in other populations, including Mexican Mestizos. Smokers were classified according to the age at onset, cigarettes per day, nicotine dependence, COPD status and therapy received.
