Alcoholism is associated with alterations of the hypothalamus–pituitary–gonadal hormone axis. We recently reported a leptin-mediated relation between the CAGn polymorphism of the androgen receptor and craving during alcohol withdrawal.
This study investigated whether the TTTAn polymorphism of the aromatase (CYP19A1) is equally linked to craving.
An association between TTTAn and compulsive craving (p = 0.029) was revealed in our sample of 118 male alcohol addicts at day of hospital admission.
Genotype-dependent subgroups showed differences in that the patients with short alleles suffered from lower compulsive craving during withdrawal than those with the longer alleles (p = 0.027).
The additional inclusion of leptin revealed no further significant association in the present study.
Our finding is a further step on the way to elucidate the genesis of craving for alcohol with its extensive underlying interactions of different genetic and non-genetic factors.
Future investigations should enroll women and consider sex hormone levels for further clarification of the observed TTTAn-craving relationship.
