Genotyping of four genetic polymorphisms in the <i>CYP1A2</i> gene in the Egyptian population

Abstract

The present study is the first to describe the frequencies of four known allelic variants of CYP1A2 among the Egyptian population. CYP1A2*1C and *1E occurred at frequencies significantly lower than that in Japanese, while similar frequencies were observed for CYP1A2*1D and *1F. The CYP1A2*1F frequency appeared to be identical to that of Caucasians. This does not exclude the possibility of the presence of new mutations relatively specific to the Egyptian population that have not been identified.
