The application of next-generation sequencing to validate D12S391 microvariation

Objective: In a paternity case, the D12S391 locus was reported as a mismatch. To confirm the existence of mutations and mutations come from father or mother. Methods: STR and next-generation sequencing technology were used to validate the sequence. Results: NGS showed the loss of one adenine between the 19.3 allele of the child and allele 20 of the mother. Conclusion: The NGS can be applied in the paternity to validate the mutation.
