Modes of inheritance:	Autosomal recessive inheritance MedGen UID: 141025 •Concept ID: C0441748 • 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). Autosomal dominant inheritance MedGen UID: 141047 •Concept ID: C0443147 • 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 heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Definition

A rare hemorrhagic disorder due to a constitutional platelet anomaly characterized by moderate to severe deficiency in both platelet alpha-granules and dense bodies, resulting in impaired platelet function and decreased aggregation responses. Patients present increased bleeding tendency with symptoms like easy bruising, or menorrhagia. [from ORDO]

Myelodysplasia

MedGen UID:: 10231
•Concept ID:: C0026985
•: Congenital Abnormality

Clonal hematopoietic stem cell disorders characterized by dysplasia (ineffective production) in one or more hematopoietic cell lineages, leading to anemia and cytopenia.

Acute leukemia

MedGen UID:: 43225
•Concept ID:: C0085669
•: Neoplastic Process

A clonal (malignant) hematopoietic disorder with an acute onset, affecting the bone marrow and the peripheral blood. The malignant cells show minimal differentiation and are called blasts, either myeloid blasts (myeloblasts) or lymphoid blasts (lymphoblasts).

Abnormal bleeding

MedGen UID:: 264316
•Concept ID:: C1458140
•: Pathologic Function

An abnormal susceptibility to bleeding, often referred to as a bleeding diathesis. A bleeding diathesis may be related to vascular, platelet and coagulation defects.
