Summaries for Dyskeratosis Congenita, Autosomal Dominant 1

About this section
OMIM : 58 Dyskeratosis congenita is a rare multisystem disorder caused by defective telomere maintenance. Clinical features are highly variable and include bone marrow failure, predisposition to malignancy, and pulmonary and hepatic fibrosis. The classic clinical triad of abnormal skin pigmentation, leukoplakia, and nail dystrophy is not always observed. Other features include premature graying of the hair, osteoporosis, epiphora, dental abnormalities and testicular atrophy, among others (review by Bessler et al., 2007 and Bessler et al., 2010). 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 show intrauterine growth retardation, microcephaly, delayed development, bone marrow failure resulting in immunodeficiency, cerebellar hypoplasia, and sometimes enteropathy. Death often occurs in childhood (summary by Walne et al., 2013). (127550)

MalaCards based summary : Dyskeratosis Congenita, Autosomal Dominant 1, also known as dyskeratosis congenita, scoggins type, is related to dyskeratosis congenita, x-linked and dyskeratosis congenita autosomal dominant. An important gene associated with Dyskeratosis Congenita, Autosomal Dominant 1 is TERC (Telomerase RNA Component), and among its related pathways/superpathways are Cell Cycle, Mitotic and Chromosome Maintenance. Affiliated tissues include bone, skin and bone marrow, and related phenotypes are ataxia and carious teeth

Disease Ontology : 12 A dyskeratosis congenita that has material basis in an autosomal dominant mutation of TERC on chromosome 3q26.2.
