Preferred Label : Dyskeratosis congenita, autosomal recessive 5;

Symbol : DKCB5;

CISMeF acronym : DKCB5;

Type : Phenotype, molecular basis known;

Included titles and symbols : Dyskeratosis congenita, autosomal dominant 4; DKCA4;

Description : Dyskeratosis congenita (DKC) is a bone marrow failure syndrome characterized by severely shortened telomeres and diverse clinical symptoms. The classic presentation of DKC includes nail dystrophy, abnormal skin pigmentation, and oral leukoplakia. Hoyeraal-Hreidarsson syndrome (HHS) is a severe clinical variant of DKC that is characterized by intrauterine growth failure, microcephaly, developmental delay, immunodeficiency, bone marrow failure, and cerebellar hypoplasia. Patients with mutations in the RTEL1 gene tend to present with HHS (summary by Walne et al., 2013). For a discussion of genetic heterogeneity of dyskeratosis congenita, see;

Inheritance : Autosomal recessive; Autosomal dominant;

Molecular basis : Caused by mutation in the regulator of telomere elongation helicase 1 gene (RTEL1, 608833.0001);

Laboratory abnormalities : Shortened telomeres in leukocytes; Fibroblasts may have normal telomere lengths;

Prefixed ID : #615190;
