Leukocytes from 200 mentally ill patients and 100 normal controls were analyzed for electrophoretic variants of arylsulfatase A. Four different variant forms were found in 15 subjects. There is a relatively high occurrence of the arylsulfatase A variants in patients with alcoholism. Twenty-one per cent (12/56) of patients with alcoholism have a variant enzyme. Only one of the 100 normal controls has a variant enzyme. (This single subject was considered normal by the criteria of the study, namely, a self-report of no current medical problem or psychiatric history. However, upon further testing, it was found that this subject has neurological and neuropsychological deficits). The hypothesis is presented that chronic alcohol intake and abnormal arylsulfatase A act in concert to elevate sulfatide levels which results in abnormalities of brain function. If this hypothesis is correct, persons in whom abnormal arylsulfatase A is expressed may be at risk to the neuropathological effects of alcohol.

This study investigated the possible effect of the pseudodeficient N-glycosylation polymorphism of the arylsulfatase A (ASA) gene on alcohol dependence among Koreans. Alcoholic patients (N=123) were more likely than control subjects to be heterozygous or homozygous for the ASA pseudodeficient N-glycosylation site (36% of alcoholics versus 20% of controls; P<0.01). Among these 123 alcoholic patients, 42 alcoholics were heterozygous and two were homozygous for the ASA pseudodeficient N-glycosylation polymorphism. This result provides evidence that the ASA pseudodeficient N-glycosylation site allele increases the risk of alcohol dependence within a Korean population.
