Acetylator phenotyping by means of a sulphadimidine tests revealed 65% of Libyan Arabs to be slow acetylators. Hence the frequency of the allele controlling slow acetylation (As) is estimated as q = 0.81 +/- 0.05. This estimate is similar to those previously recorded in European and adjacent Middle Eastern populations.
