The IIIa and IIIb electrophoretic variants of arylsulfatase A (EC 3.1.6.8) are 12 times more prevalent in alcoholic than in nonalcoholic populations. These variant enzymes, found in a subset of alcoholics, possess the pseudodeficient Asn350-Ser mutation of arylsulfatase A and, consequently, lack an N-linked glycan unit. These genetically determined variants of arylsulfatase A show reduced intracellular half-life, and cells from such individuals possess reduced enzymic activity. We propose that this polymorphism is an underlying genetic and biochemical factor contributing to the neuropathology and/or addiction pathway of this disease. [ABSTRACT FROM AUTHOR] |
