Novel TBX5 mutations and molecular mechanism for Holt-Oram syndrome.
The Holt-Oram syndrome (OMIM 142900) is an autosomal dominant disorder with clinical features characterised by a variety of skeletal malformations and congenital heart defects. The gene for Holt-Oram syndrome has been identified as TBX5 on chromosome 12q24. TBX5 encodes a protein of 518 amino acids that belongs to the family of the T box transcriptional factors, 11 and is expressed in embryonic...
متن کاملProstate Cancer in a Male with Holt-Oram Syndrome: First Clinical Association of the TBX5 Mutation
Holt-Oram syndrome is an autosomal dominant disorder which is caused by mutations of TBX5 and is characterised by cardiac and skeletal abnormalities. TBX5 is part of the T-box gene family and is thought to upregulate tumour cell proliferation and metastasis when mutated. We report the first clinical case of prostate cancer in an individual with Holt Oram syndrome.
متن کاملNovel mutations in the TBX5 gene in patients with Holt-Oram Syndrome
The Holt-Oram syndrome (HOS) is an autosomal dominant condition characterized by upper limb and cardiac malformations. Mutations in the TBX5 gene cause HOS and have also been associated with isolated heart and arm defects. Interactions between the TBX5, GATA4 and NKX2.5 proteins have been reported in humans. We screened the TBX5, GATA4, and NKX2.5 genes for mutations, by direct sequencing, in 3...
متن کاملIdentification of new mutations in the TBX5 gene in patients with Holt-Oram syndrome.
H olt-Oram syndrome (HOS) (MIM 142900), first described by Holt and Oram in 1960, is characterised by malformations of the upper limbs involving mainly the pre-axial ray and variable cardiac defects, most of them septation defects. This autosomal dominant inherited condition occurs in approximately 1 in 100 000 live births and shows high penetrative and variable intrafamilial and interfamilial ...
متن کاملAtrial Fibrillation and Other Clinical Manifestations of Altered TBX5 Dosage in Typical Holt-Oram Syndrome.
Atrial Fibrillation and Other Clinical Manifestations of Altered TBX5 Dosage in Typical Holt–Oram Syndrome To the editor: We were pleased to read the recent study in Circulation Research by Postma et al1 that describes an activation mutation in TBX5 that causes Holt–Oram syndrome. These exciting findings validate prior studies (reviewed elsewhere2) showing that cytogenetic abnormalities that pr...
