Cardiogenesis is a complex phenomenon: its success— and ultimately life births—depends on factors acting in a combinatorial or hierarchical fashion and turning on and off gene transcription. Actually, the incidence of cardiac defects at birth is relatively high (1% to 2%), and our comprehension of these phenomena very limited. Hence, the role of transcription factors in cardiac specification an...
TBX5 is a T-box transcriptional factor required for cardiogenesis and limb development. TBX5 mutations cause Holt-Oram syndrome characterized by congenital heart defects and upper limb deformations. Here we establish a novel function for TBX5 in pre-mRNA splicing, and we show that this function is relevant to the pathogenesis of Holt-Oram syndrome, providing a novel pathogenic mechanism for the...
BACKGROUND Holt-Oram syndrome (HOS) is an autosomal dominant disorder characterised by upper limb anomalies and congenital heart defects. We present epidemiological and clinical aspects of HOS patients using data from EUROCAT (European Surveillance of Congenital Anomalies) registries. METHODS The study was based on data collected during 1990-2011 by 34 registries. The registries are populatio...
BACKGROUND/AIMS Congenital heart defects (CHD) can occur with upper limbs deformities. Holt-Oram syndrome is the main type of heart-hand syndromes, characterized by upper limb radial ray malformations, CHD and/or conduction abnormalities. Mutations of the TBX5 gene, most of which are found within the T-box domain, are one cause of the disease. We aimed to find the cause of the disease in a fami...
