Paternity testing results should not rely on a single genetic marker due to mutation risks. Use combined probability of exclusion and paternity index thresholds for accurate paternity inclusion or exclusion.

Area of Science:

  • Forensic genetics
  • Human identification
  • Population genetics

Context:

  • Paternity testing relies on analyzing short tandem repeat (STR) loci.
  • Genetic mutations can complicate the interpretation of paternity test results.
  • Accurate evaluation of genetic data is crucial for legal and familial contexts.

Purpose:

  • To establish recommendations for evaluating genetic analysis results in paternity testing, specifically addressing the impact of mutations.
  • To define criteria for paternity inclusion and exclusion based on genetic evidence.
  • To guide the interpretation of paternity index and combined probability of exclusion.

Summary:

  • This study analyzed 15 short tandem repeat (STR) loci across 100 true and 100 false paternity trio cases.

  • Observed mismatch alleles and paternity index distributions highlight the influence of mutations.
  • Recommendations emphasize avoiding single-locus exclusions and utilizing combined probability of exclusion and paternity index thresholds.

    • Impact:

    • Provides a framework for robust paternity testing, minimizing errors caused by genetic mutations.
    • Enhances the reliability of scientific evidence in paternity determination.
    • Suggests adding more genetic markers when initial results do not meet established thresholds.
