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." /><meta name="robots" content="index,nofollow,noarchive" />

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. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK22301#dkc.Summary" target="NBK22301">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK22301#dkc.GeneReview_Scope" target="NBK22301">GeneReview Scope</a>  |  <a class="medgenPMinfo" href="/books/NBK22301#dkc.Diagnosis" target="NBK22301">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK22301#dkc.Clinical_Characteristics" target="NBK22301">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK22301#dkc.Genetically_Related_Allelic_Disorder" target="NBK22301">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK22301#dkc.Differential_Diagnosis" target="NBK22301">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK22301#dkc.Management" target="NBK22301">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK22301#dkc.Genetic_Counseling" target="NBK22301">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK22301#dkc.Resources" target="NBK22301">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK22301#dkc.Molecular_Genetics" target="NBK22301">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK22301#dkc.Chapter_Notes" target="NBK22301">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK22301#dkc.References" target="NBK22301">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />Dyskeratosis congenita is a bone marrow failure syndrome classically characterized by the triad of abnormal skin pigmentation, nail dystrophy, and leukoplakia of the oral mucosa. Progressive bone marrow failure occurs in over 80% of cases and is the main cause of early mortality. The phenotype is highly variable, and affected individuals may have multiple additional features, including pulmonary fibrosis, liver cirrhosis, premature hair loss and/or graying, osteoporosis, atresia of the lacrimal ducts, and learning difficulties. Predisposition to malignancy is an important feature. The disorder is caused by defects in the maintenance of telomeres (summary by Kirwan and Dokal, 2008).&#13;
For a discussion of genetic heterogeneity of dyskeratosis congenita, see DKCA1 (127550).  <a target="_blank" href="http://www.omim.org/entry/224230">http://www.omim.org/entry/224230</a></div></div>

<div class="spaceAbove">Aplastic anemia is a serious disorder of the bone marrow that affects between 2 and 5 persons per million per year. About 75% of these cases are classified as idiopathic (Young, 2000). In about 15% of cases a drug or infection can be identified that precipitates the aplasia, although why only some individuals are susceptible is unclear. In about 5 to 10% of patients, the aplastic anemia is constitutional--i.e., is familial or presents with one or more associated somatic abnormalities (summary by Vulliamy et al., 2002).</div>
