Identification of a novel cytosolic aldehyde dehydrogenase allele, ALDHIAI*4

This paper reports the identification of a novel cytosolic aldehyde dehydrogenase 1 (ALDHIAI) allele. One hundred and sixty-two Indo-Trinidadian and 85 Afro-Trinidadian individuals were genotyped. A novel ALDHIAI allele, ALDHIAI*4, was identified in an Indo-Trinidadian alcoholic with an A inserted at position -554 relative to the translational start site, +1. It was concluded that a wider cross-section of individuals needs to be evaluated in order to determine the representative frequency of the allele, and to see if it is associated with risk of alcoholism.
