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 (DKC) is classically defined by the triad of abnormal skin pigmentation, nail dystrophy, and leukoplakia of the oral mucosa. It is characterized by short telomeres. 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, hepatopulmonary syndrome, premature hair loss and/or graying, osteoporosis, atresia of the lacrimal ducts, gastrointestinal disease (esophageal strictures or enteropathy), and learning difficulties. Males may have testicular atrophy. Predisposition to malignancy, including hematologic malignancy and squamous cell carcinoma, is an important feature. The disorder is caused by defects in the maintenance of telomeres (summary by Kirwan and Dokal, 2008; Gorgy et al., 2015; Schratz et al., 2023).&#13;
Hoyeraal-Hreidarsson syndrome (HHS) refers to a clinically severe variant of DKC that is characterized by multisystem involvement and early onset in utero. Patients with HHS can show intrauterine growth retardation, microcephaly, delayed development, bone marrow failure, immunodeficiency, cerebellar hypoplasia, immune defects (B-cell lymphopenia and hypogammaglobulinemia), and gastrointestinal manifestations, including enterocolitis and enteropathy. Death often occurs in childhood (summary by Walne et al., 2013).&#13;

Cryptorchidism can result in infertility and increases risk for testicular tumors. Testicular descent from abdomen to scrotum occurs in 2 distinct phases: the transabdominal phase and the inguinoscrotal phase (summary by Gorlov et al., 2002).</div>
