Abstract excerpt
Blood lead (BPb) concentrations are elevated in essential tremor (ET) cases. The delta-amino-levulinic acid dehydratase (ALAD) gene codes for ALAD, the principal enzyme involved in lead kinetics. Carriers of the ALAD-2 allele may be more susceptible to lead toxicity. The objective of this study was to test, using a case-control design, whether an interaction between BPb concentration and ALAD allele status...
