Abstract excerpt
Typing of STR (short tandem repeat) alleles is used in a variety of applications in clinical molecular pathology, including evaluations for maternal cell contamination. Using a commercially available STR typing assay for maternal cell contamination performed in conjunction with prenatal diagnostic testing, we were posed with apparent nonmaternity when the two fetal samples did not demonstrate the expected...
