A haplotype‐specific linkage disequilibrium pattern of monoamine oxidase A gene associated with regular smoking in women

Abstract

Cigarette smoking in women is raising a public health problem. The X‐linked monoamine oxidase A (MAOA) was considered as a susceptibility gene to substance abuse of tobacco, but the evolutionary effect of MAOA may lead to a positive or negative association between genetic variations and smoking development among study regions.
