The short tandem repeat loci hTPO, THO1 and FGA.

This paper focuses on the three well-established short tandem repeats HumhTPO (human thyroid peroxidase gene), HumTHO1 (human tyrosine hydroxylase gene) and HumFGA (human alpha fibrinogen gene). We present sequencing data which include the sequences of all the different primer pairs used so far, as well as results from a population study which was carried out on an American Black and a southwestern German population. All data are compared with previously published studies. A test for homogeneity confirmed that non-European populations possess different genetic pools for each of the three loci under investigation.

Subtyping of coagulation factor XIIIA.

An extended polymorphism of the coagulation factor XIIIA can routinely be detected in human plasma samples and white cell lysates by isoelectric focusing in polyacrylamide gels containing 3 M urea in the pH range 5-8. Analyses of 184 families with 513 children confirmed the formal model proposed by Suzuki et al. [Am J Hum Genet 1988;43:170-174]. Four common alleles, F XIIIA*1A, 1B, 2A, 2B, at an autosomal locus control the expression of ten phenotypes. On the basis of the population sample from southwest Germany the frequencies of the common alleles F XIIIA*1A, 1B, 2A, 2B were calculated as 0.175, 0.609, 0.011, and 0.205, respectively.
