Missense mutation in a patient with X-linked dyskeratosis congenita.

دیسکراتوز مادرزادی: گزارش موردی

Background: Dyskeratosis Congenita (DC) is a rare inherited disease with an incidence of approximately one case per million population. The disease is characterized by a classic triad: nail changes, color reticulated skin and oral leukoplakia. In these patients, premature death is often associated with bone marrow failure, infections, pulmonary complications, or malignancy. Three patterns of in...

Case report X-linked dyskeratosis congenita: restrictive pulmonary disease and a novel mutation

Dyskeratosis congenita (DC) is a rare inherited multisystem disorder characterised by lesions of the skin and appendages. Bone marrow failure occurs in 80% of patients. The gene for the X-linked form of DC has been identified on Xq28 and designated as DKC1. Pulmonary manifestations have rarely been reported. It is not known whether there is a respiratory disease peculiar to these patients and, ...

Pathogenic NAP57 mutations decrease ribonucleoprotein assembly in dyskeratosis congenita.

X-linked dyskeratosis congenita (DC) is a rare bone marrow failure syndrome caused by mostly missense mutations in the pseudouridine synthase NAP57 (dyskerin/Cbf5). As part of H/ACA ribonucleoproteins (RNPs), NAP57 is important for the biogenesis of ribosomes, spliceosomal small nuclear RNPs, microRNAs and the telomerase RNP. DC mutations concentrate in the N- and C-termini of NAP57 but not in ...
