MedGen UID:
19351
Concept ID:
C0032197
Disease or Syndrome
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.

Dyskeratosis congenita, X-linked
MedGen UID:
216941
Concept ID:
C1148551
Disease or Syndrome
Dyskeratosis congenita and related telomere biology disorders (DC/TBD) are caused by impaired telomere maintenance resulting in short or very short telomeres. The phenotypic spectrum of telomere biology disorders is broad and includes individuals with classic dyskeratosis congenita (DC) as well as those with very short telomeres and an isolated physical finding. Classic DC is characterized by a triad of dysplastic nails, lacy reticular pigmentation of the upper chest and/or neck, and oral leukoplakia, although this may not be present in all individuals. People with DC/TBD are at increased risk for progressive bone marrow failure (BMF), myelodysplastic syndrome or acute myelogenous leukemia, solid tumors (usually squamous cell carcinoma of the head/neck or anogenital cancer), and pulmonary fibrosis. Other findings can include eye abnormalities (epiphora, blepharitis, sparse eyelashes, ectropion, entropion, trichiasis), taurodontism, liver disease, gastrointestinal telangiectasias, and avascular necrosis of the hips or shoulders. Although most persons with DC/TBD have normal psychomotor development and normal neurologic function, significant developmental delay is present in both forms; additional findings include cerebellar hypoplasia (Hoyeraal Hreidarsson syndrome) and bilateral exudative retinopathy and intracranial calcifications (Revesz syndrome and Coats plus syndrome). Onset and progression of manifestations of DC/TBD vary: at the mild end of the spectrum are those who have only minimal physical findings with normal bone marrow function, and at the severe end are those who have the diagnostic triad and early-onset BMF.

MedGen UID:
321945
Concept ID:
C1832388
Disease or Syndrome
RUNX1 familial platelet disorder with associated myeloid malignancies (RUNX1-FPDMM) is characterized by prolonged bleeding and/or easy bruising and an increased risk of developing a hematologic malignancy. RUNX1-FPDMM is characterized by thrombocytopenia with normal platelet size; bleeding is often greater than expected due to qualitative platelet dysfunction. Myeloid malignancies are the most common, including acute myelogenous leukemia (and myelodysplastic syndrome. T- and B-cell acute lymphoblastic leukemias and lymphomas have also been reported, as well as skin manifestations (e.g., eczema, psoriasis).

Monosomy 7 myelodysplasia and leukemia syndrome 1
MedGen UID:
381529
Concept ID:
C1854978
Disease or Syndrome
Monosomy 7 myelodysplasia and leukemia syndrome-1 (M7MLS1) is an autosomal dominant hematologic disorder with highly variable manifestations. Most patients present in early childhood with pancytopenia and dyspoietic or dysplastic changes in the bone marrow. These abnormalities are almost always associated with monosomy 7 in the bone marrow. In severely affected individuals, the phenotype progresses to frank myelodysplastic syndrome (MDS) or acute myelogenous leukemia (AML). Less severely affected individuals may have transient thrombocytopenia or anemia, or have normal peripheral blood counts with transient bone marrow abnormalities or transient monosomy 7. Germline mutations in the SAMD9L gene, located on chromosome 7q, have a gain-of-function suppressive effect on the cell cycle, resulting in decreased cellular proliferation. It is hypothesized that this germline defect leads to selective pressure favoring somatic loss of the chromosome 7 harboring the mutant allele (adaptation by aneuploidy) (summary by Wong et al., 2018). Monosomy 7 or partial deletion of the long arm of chromosome 7 (7q-) is a frequent cytogenetic finding in the bone marrow of patients with myelodysplasia and acute myelogenous leukemia. Furthermore, monosomy 7 or 7q- is the most frequent abnormality of karyotype in cases of AML that occur after cytotoxic cancer therapy or occupational exposure to mutagens. The age distribution of de novo cases shows peaks in the first and fifth decades. Monosomy 7 is found in about 5% of de novo and 40% of secondary cases of AML. These findings suggest that loss of certain genes at this region is an important event in the development of myelodysplasia (summary by Shannon et al., 1989). Genetic Heterogeneity of Monosomy 7 Myelodysplastic and Leukemia Syndrome See also M7MLS2 (619041), caused by germline mutation in the SAMD9 gene (610457) on chromosome 7q21.
Diamond-Blackfan anemia 1
MedGen UID:
390966
Concept ID:
C2676137
Disease or Syndrome
Diamond-Blackfan anemia (DBA) is characterized by a profound normochromic and usually macrocytic anemia with normal leukocytes and platelets, congenital malformations in up to 50%, and growth deficiency in 30% of affected individuals. The hematologic complications occur in 90% of affected individuals during the first year of life. The phenotypic spectrum ranges from a mild form (e.g., mild anemia or no anemia with only subtle erythroid abnormalities, physical malformations without anemia) to a severe form of fetal anemia resulting in nonimmune hydrops fetalis. DBA is associated with an increased risk for acute myelogenous leukemia (AML), myelodysplastic syndrome (MDS), and solid tumors including osteogenic sarcoma.
Deafness-lymphedema-leukemia syndrome
MedGen UID:
481294
Concept ID:
C3279664
Disease or Syndrome
Primary lymphedema with myelodysplasia, also known as Emberger syndrome, is a rare disorder characterized by childhood-onset lymphedema of the lower limbs, with lymphoscintigraphy suggestive of lymphatic vessel hypoplasia, and genital lymphatic abnormalities. Myelodysplasia is usually with monosomy 7. Multiple warts, deafness, and minor anomalies (mild hypotelorism, neck webbing, and slender fingers) may also be present (summary by Mansour et al., 2010).
Monocytopenia with susceptibility to infections
MedGen UID:
481660
Concept ID:
C3280030
Disease or Syndrome
This primary immunodeficiency, designated IMD21, DCML, or MONOMAC, is characterized by profoundly decreased or absent monocytes, B lymphocytes, natural killer (NK) lymphocytes, and circulating and tissue dendritic cells (DCs), with little or no effect on T-cell numbers. Clinical features of IMD21 are variable and include susceptibility to disseminated nontuberculous mycobacterial infections, papillomavirus infections, opportunistic fungal infections, and pulmonary alveolar proteinosis. Bone marrow hypocellularity and dysplasia of myeloid, erythroid, and megakaryocytic lineages are present in most patients, as are karyotypic abnormalities, including monosomy 7 and trisomy 8. In the absence of cytogenetic abnormalities or overt dysplasia, hypoplastic bone marrow may initially be diagnosed as aplastic anemia. Bone marrow transplantation is the only cure. Some patients may have an increased risk of miscarriage. Both autosomal dominant transmission and sporadic cases occur. Less common manifestations of GATA2 deficiency include lymphedema and sensorineural hearing loss, a phenotype usually termed 'Emberger syndrome' (614038) (summary by Bigley et al. (2011), Hsu et al. (2011), and Spinner et al. (2014)).
Myelodysplastic syndrome
MedGen UID:
483005
Concept ID:
C3463824
Neoplastic Process
Myelodysplastic syndrome (MDS) is a heterogeneous group of clonal hematologic stem cell disorders characterized by ineffective hematopoiesis resulting in low blood counts, most commonly anemia, and a risk of progression to acute myeloid leukemia (AML; 601626). Blood smears and bone marrow biopsies show dysplastic changes in myeloid cells, with abnormal proliferation and differentiation of 1 or more lineages (erythroid, myeloid, megakaryocytic). MDS can be subdivided into several categories based on morphologic characteristics, such as low-grade refractory anemia (RA) or high-grade refractory anemia with excess blasts (RAEB). Bone marrow biopsies of some patients show ringed sideroblasts (RARS), which reflects abnormal iron staining in mitochondria surrounding the nucleus of erythrocyte progenitors (summary by Delhommeau et al., 2009 and Papaemmanuil et al., 2011).

Kostmann syndrome
MedGen UID:
1713491
Concept ID:
C5235141
Disease or Syndrome
Severe congenital neutropenia-3 is an autosomal recessive bone marrow failure disorder characterized by low numbers of neutrophils, increased susceptibility to bacterial and fungal infections, and increased risk of developing myelodysplastic syndrome or acute myeloid leukemia. In addition, patients with HAX1 mutations affecting both isoform A and B of the gene develop neurologic abnormalities (summary by Boztug et al., 2010). The Swedish physician Rolf Kostmann (1956) described an autosomal recessive hematologic disorder, termed infantile agranulocytosis, with severe neutropenia with an absolute neutrophil count below 0.5 x 10(9)/l and early onset of severe bacterial infections. The disorder was later termed Kostmann syndrome (Skokowa et al., 2007). Lekstrom-Himes and Gallin (2000) discussed severe congenital neutropenia in a review of immunodeficiencies caused by defects in phagocytes. In addition to Kostmann agranulocytosis, recessively inherited neutropenic syndromes include congenital neutropenia with eosinophilia (257100), Chediak-Higashi syndrome (214500), and Fanconi pancytopenic syndrome (see 227650). For a phenotypic description and a discussion of genetic heterogeneity of severe congenital neutropenia, see SCN1 (202700).
VEXAS syndrome
MedGen UID:
1765785
Concept ID:
C5435753
Disease or Syndrome
VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic syndrome) is an adult-onset inflammatory disease that primarily affects males and is caused by somatic, not germline, mutations. The disorder is characterized by adult onset of rheumatologic symptoms at a mean age of 64 years. Features include recurrent fevers, pulmonary and dermatologic inflammatory manifestations, vasculitis, deep vein thrombosis, arthralgias, and ear and nose chondritis. Laboratory studies indicate hematologic abnormalities, including macrocytic anemia, as well as increased levels of acute-phase reactants; about half of patients have positive autoantibodies. Bone marrow biopsy shows degenerative vacuolization restricted to myeloid and erythroid precursor cells, as well as variable hematopoietic dyspoiesis and dysplasias. The condition does not respond to rheumatologic medications and the features may result in premature death (summary by Beck et al., 2020).
Monosomy 7 myelodysplasia and leukemia syndrome 2
MedGen UID:
1762901
Concept ID:
C5436668
Disease or Syndrome
Monosomy 7 myelodysplasia and leukemia syndrome-2 (M7MLS2) is an autosomal dominant hematologic disorder characterized by onset of pancytopenia, acute myelogenous leukemia (AML), and variable features of myelodysplastic syndrome (MDS) usually in the first decades of life. Bone marrow cells show monosomy 7. Germline mutations in the SAMD9 gene, located on chromosome 7q, have a gain-of-function suppressive effect on the cell cycle, resulting in decreased cellular proliferation. It is hypothesized that this germline defect leads to selective pressure favoring somatic loss of the chromosome 7 harboring the mutant allele (adaptation by aneuploidy) (summary by Wong et al., 2018).
