Remarks: comment
Allele: On which allele is the variant located? Does not necessarily imply inheritance! 'Paternal' (confirmed or inferred), 'Maternal' (confirmed or inferred), 'Parent #1' or #2 for compound heterozygosity without having screened the parents, 'Unknown' for heterozygosity without having screened the parents, 'Both' for homozygozity.
Type: Type of variant at DNA level; note that the variant type can also be derived from the variant description (for all levels).
All options:
- Substitution
- Deletion
- Duplication
