STR typing of 77-year-old umbilical cord in maternity test

摘要

We performed a maternity test using DNA extracted from an umbilical cord that had been preserved for 77 years. We used 15 short tandem repeat (STR) loci, D8S1179, D21S11, D7S820, CFS1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818, and FGA, for the DNA analysis The 15 STR loci were correctly typed from the umbilical cord. The maternity probability was 0 999937, and the exclusion probability was 0.999629.
