STRP Screening Sets for the human genome at 5 cM density

BACKGROUND: Short tandem repeat polymorphisms (STRPs) are powerful tools for gene mapping and other applications. A STRP genome scan of 10 cM is usually adequate for mapping single gene disorders. However mapping studies involving genetically complex disorders and especially association (linkage disequilibrium) often require higher STRP density. RESULTS: We report the development of two separate 10 cM human STRP Screening Sets (Sets 12 and 52) which span all chromosomes. When combined, the two Sets contain a total of 782 STRPs, with average STRP spacing of 4.8 cM, average heterozygosity of 0.72, and total sex-average coverage of 3535 cM. The current Sets are comprised almost entirely of STRPs based on tri- and tetranucleotide repeats. We also report correction of primer sequences for many STRPs used in previous Screening Sets. Detailed information for the new Screening Sets is available from our web site: . CONCLUSION: Our new human STRP Screening Sets will improve the quality and cost effectiveness of genotyping for gene mapping and other applications

Inspired by the notion and observation that judicial policies often lack solid scientific evidence, this themed issue covers a wide range of subjects: from anti-corruption policies, punishments, and international criminal tribunals to obligatory facilities for drug addicts, police policies and measures to restrict speeding. With regard to these issues, there are three questions that constantly recur: What are the objectives of this policy? Why are the applicable means considered to contribute to the realisation of these objectives? Or: what is the underlying policy theory? Are these assumptions supported by empirical expertise
