Abstract
Catechol-O-methyltransferase (COMT) is a key regulator of pain perception, cognitive function, and affective mood. Three common haplotypes of the humanCOMTgene, divergent in two synonymous and one nonsynonymous position, code for differences in COMT enzymatic activity and are associated with pain sensitivity. Haplotypes divergent in synonymous changes exhibited the largest difference in COMT enzymatic activity, due to a reduced amount of translated protein. The majorCOMThaplotypes varied with respect to messenger RNA local stem-loop structures, such that the most stable structure was associated with the lowest protein levels and enzymatic activity. Site-directed mutagenesis that eliminated the stable structure restored the amount of translated protein. These data highlight the functional significance of synonymous variations and suggest the importance of haplotypes over single-nucleotide polymorphisms for analysis of genetic variations.

Clones corresponding to all three haplotypes and including the transcriptional start site were constructed by use of the unique restriction enzyme Bsp MI. The gene coding region containing all three SNPs was cut and inserted into the plasmids through use of the S-COMT (BG290167) and MB-COMT (BI835796) clones containing the entire COMT 5â² and 3â² ends as a backbone vector.
