A study on the short tandem repeat system ACTBP2 (SE33) in an Austrian population sample

Abstract

Population genetic studies were carried out on 932 caucasians from Austria using the short tandem repeat system ACTBP2 (SE33). A sequenced allelic ladder was used for typing (Möller et al. 1995). After native polyacrylamide gel electrophoresis all 26 alleles of the ladder were found as well as 194 alleles which migrated differently from those in the ladder. Forensically relevant parameters were calculated (discrimination power: 0.989, mean exclusion chance: 0.854, observed heterozygosity 0.946). An allele consisting of 9 repeats which is not part of the allelic ladder was also found. In 692 meioses 5 mutations were found (mutation rate 0.72%).
