An allele heterogeneity in a short tandem repeat at the human dihydrofolate reductase pseudogene (DHFRP2) was detected using non-denaturing gel electrophoresis and ethidium bromide staining. Sequence analysis of the allele, designated 9A, revealed the C to A substitution in the 8th AAAC repeat. A survey of 16 worldwide human populations showed that this mutation was spread through five continents at a relatively high frequency (up to p = 0.19 in Europeans). Some statistical parameters of forensic interest were also calculated (h, PD, EC and PIC) for this polymorphism. This type of heterogeneity stresses the complexity of STR variation.
