What is a gene mutation and how does it impact paternity testing?
• Genes are composed of four chemicals (nucleotides) called adenine, cytosine, guanine and thymine. The order of these nucleotides determines the genetic sequence. In a mutation, one or a few of these nucleotides are changed or missing in a sequence. Any testing individual can have a mutation. If a mutation occurs in an area of the DNA that is being used for DNA testing, the result will be not match between the mother and the child, or a child and alleged father. The results in a single exclusion with one probe and the two individuals will match on all remaining probes used in the testing. When a mutation is suspected, additional probes are used in the testing to confirm a mutation has occurred and not exclusion. The calculating of the PI and POP includes the mutation frequency of that particular probe. Exclusions are confirmed in DNA testing after two mismatches are seen. • * Standard testing is 7-10 days. If a mutation is observed this will delay testing for up to 4 business days. Wh
