Sclerosteosis is a severe, rare, autosomal recessive bone condition that is characterized by a progressive craniotubular hyperostosis. The main features are a significant sclerosis of the long bones, ribs, pelvis, and skull, leading to facial distortion and entrapment of cranial nerves. Clinical features include a tall stature, nail dysplasia, cutaneous syndactyly of some fingers, and raised intracranial pressure. The sclerosteosis gene has been mapped to chromosome 17q12-21 and is currently known as the SOST gene encoding the sclerostin protein. Here, we report on one familial and one isolated case of Brazilian origin with the clinical and molecular diagnosis of sclerosteosis. The radiological and clinical features are described, and the diagnosis of sclerosteosis was confirmed in both cases by mutation analysis of the SOST gene showing a homozygous nonsense mutation (Trp124X) in the two patients. We reported this mutation previously in other sclerosteosis patients from a consanguineous Brazilian family. Interestingly, all three families were from the same state in Brazil, but they denied familial relationship. These patients confirm the clinical picture as found in other cases with a loss of function mutation in the SOST gene.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
