Validation of PHASE for deriving N-acetyltransferase 2 haplotypes in the Western Cape mixed ancestry population.

Background: There is a shortage of data on the accuracy of statistical methods for the prediction of N-acetyltransferase 2 () haplotypes in the mixed ancestry population of the Western Cape.

Objective: This study aimed to identify the haplotypes and assess the accuracy of PHASE version 2.1.
