Different TBX5 interactions in heart and limb defined by Holt-Oram syndrome mutations.
To better understand the role of TBX5, a T-box containing transcription factor in forelimb and heart development, we have studied the clinical features of Holt-Oram syndrome caused by 10 different TBX5 mutations. Defects predicted to create null alleles caused substantial abnormalities both in limb and heart. In contrast, missense mutations produced distinct phenotypes: Gly80Arg caused signific...
متن کاملNovel 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 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 کاملHolt-Oram syndrome.
A29-year-old woman presented with dizziness. Physical and radiographic examinations showed skeletal hand malformations, ie, digitalized triphalangeal thumbs and dystrophy of the carpal bones. When she was 15 years old, an atrial septal defect had been repaired. ECG recordings showed abnormalities of atrial excitation such as a wandering pacemaker, atrial ectopic activity, AV-nodal block, and si...
