Population genetics of HPRTB, F13B, and LPL in Pernambuco, Northeast Brazil

One hundred thirty-four unrelated Northeast Brazilian individuals were type d for the HPRTB, F13B, and LPL short tandem repeats (STRs). DNA was amplifi ed by specific primers and identified by silver staining of polyacrylamide gels. The allelic frequencies of these loci were in agreement with Hardy-We inberg proportions. The most frequent alleles were HPRTB*13, F13B*10, LPL*1 0. The combined probability of paternity and the discrimination power of th ese 3 STRs were high, permitting their utilization for forensic science pur poses.
