Inheritance tracking lets you mark where a variant appears to come from when you review family data. The mark sits next to the genotype so the inheritance note stays attached to the variant during review.
Available marks
- Maternal: the variant appears to come from the mother.
- Paternal: the variant appears to come from the father.
- Possible de novo: the variant may be new in the child.
- Probably maternal: the evidence points to the mother but is not complete.
- Probably paternal: the evidence points to the father but is not complete.
How to add a mark
Click the genotype value and choose Set inheritance mark. You can change or remove the mark later if new family data changes the interpretation.
When uncertainty matters
Family data is often incomplete. One parent may be unavailable, read quality may vary, or a possible de novo mutation may need confirmation. Use the probable marks when the direction is useful but not final.
Inheritance marks are notes for review. They do not prove clinical causation, and they should be checked against sample quality, family relationships, and source evidence.
