Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).

Definition

Congenital dyserythropoietic anemia type II (CDA II) is the most common form of CDA (see this term) characterized by anemia, jaundice and splenomegaly and often leading to liver iron overload and gallstones. [from ORDO]
