Distinct ribosome maturation defects in yeast models of Diamond-Blackfan anemia and Shwachman-Diamond syndrome.
BACKGROUND Diamond-Blackfan anemia and Shwachman-Diamond syndrome are inherited bone marrow failure syndromes linked to defects in ribosome synthesis. The purpose of this study was to determine whether yeast models for Diamond-Blackfan anemia and Shwachman-Diamond syndrome differed in the mechanism by which ribosome synthesis was affected. DESIGN AND METHODS Northern blotting, pulse-chase ana...
متن کاملSHWACHMAN-DIAMOND SYNDROME Clinical, Genetic and Radiological Study
9 Conclusions: This study expanded the phenotypic features of SDS to include primary low-turnover osteoporosis and structural alterations in the brain. Pancreatic MRI showed characteristic changes in the SBDS mutation-positive patients while these were absent in the mutation-negative patients, suggesting that MRI can be used to differentiate patients harboring SBDS mutations from those without ...
متن کاملDefective ribosome assembly in Shwachman-Diamond syndrome.
Shwachman-Diamond syndrome (SDS), a recessive leukemia predisposition disorder characterized by bone marrow failure, exocrine pancreatic insufficiency, skeletal abnormalities and poor growth, is caused by mutations in the highly conserved SBDS gene. Here, we test the hypothesis that defective ribosome biogenesis underlies the pathogenesis of SDS. We create conditional mutants in the essential S...
متن کاملHematologically important mutations: Shwachman-Diamond syndrome.
Shwachman-Diamond syndrome (SDS) is a rare autosomal recessive disorder characterized by exocrine pancreatic insufficiency, bone marrow dysfunction, and skeletal abnormalities. The Shwachman-Bodian-Diamond syndrome (SBDS) gene was identified as a causative gene for SDS in 2003, and genetic analyses of SDS have been performed. Over the last 4 years, a number of different mutations affecting the ...
متن کاملA case of Shwachman–Diamond syndrome
Shwachman–Diamond syndrome (SDS) is an autosomal recessive disorder (OMIM 260400), characterized by exocrine pancreatic insufficiency, skeletal abnormalities and bone marrow (BM) dysfunction, with a risk, as high as 30%, to develop myelodysplastic syndrome and/or acute myeloid leukaemia (MDS/AML). The SBDS gene (OMIM 607744) is localized on chromosome 7 at the band q11 and mutations of this gen...
