The rat tyrosine hydroxylase gene (TH) from a panel of outbred and inb
red rat strains has been analysed by Southern blotting, restriction-en
donuclease mapping and direct sequencing of PCR-amplified products for
detecting DNA polymorphisms. Five polymorphic sites have been charact
erized. This information may be used in pharmacogenetic studies to det
ermine the influence of the TH gene in animal models of affective diso
rders and addictive behaviours. (C) 1997 Elsevier Science B.V.
