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).
Autosomal recessive inheritance (Orphanet)

Definition

A subtype of type 2 von Willebrand disease characterized by a bleeding disorder associated with a marked decrease in the affinity of the Willebrand factor (VWF) for factor VIII (FVIII). Abnormal bleeding manifestations are less frequent in this VWD subtype than in other forms of the disease. The disease manifests mainly as soft tissue bleeding (haematoma, post-operative bleeding, etc.). [from ORDO]
