Legend
Please note that a short description of a certain column can be displayed when you move your mouse cursor over the column's header and hold it still. Below, a more detailed description is shown per column.
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.
