Holt-Oram syndrome is a disorder that affects approximately 1 in 100,000 individuals. It is characterized by abnormalities in the bones of the upper limb, a family or personal history of a congenital heart malformation, and/or an abnormality in the electrical impulses that coordinate the muscle contractions of the heart (cardiac conduction defect) , associated with a congenital heart lesion
From GeneReviewsHolt-Oram syndrome (HOS) is characterized by upper-limb defects, congenital heart malformation, and cardiac conduction disease. Upper-limb malformations may be unilateral, bilateral/symmetric, or bilateral/asymmetric and can range from triphalangeal or absent thumb(s) to phocomelia Holt-Oram syndrome (HOS) is characterized by upper-limb defects, congenital heart malformation, and cardiac conduction disease.

H., the propositus, was an 8-year-old girl in whom a heart murmur had been detected at the age of three years. She had frequent pneumonia and left lower lobe atelectasis Holt-Oram syndrome is a rare genetic disorder characterized by abnormalities of the heart and upper limbs. It is an autosomal dominant disease, with mutations occurring on the long arm of chromosome 12, and patients present with congenital heart disease accompanied with deformities of the forearms and hands. A thorough workup is needed to establish the diagnosis, and treatment includes. Holt-Oram syndrome (caused by mutations in the TBX5 gene) is the best known of these heart-hand syndromes
Holt-Oram syndrome is a developmental disorder characterized by distinctive malformations of the bones of the thumbs and upper limbs and abnormalities of the heart. The syndrome shows a marked variability in phenotype, with radial ray defects ranging from minor thumb abnormality through to severe reduction defect or phocomelia Holt-Oram syndrome is the prototype of heart-hand syndromes and has recently been mapped to the long arm of chromosome 12 (12q2). 1 It must be differentiated from heart-hand syndrome type II (Tobatznik's syndrome) and heart-hand syndrome type III (MIM No. 140450 ), which are phenotypically similar. The latter do not map to 12q2, and atrial. Holt-Oram syndrome is caused by mutations in the transcription factor TBX5, which is critical for development of the heart and upper limbs. No contributory environmental factors are known. A number of syndromes phenotypically resemble Holt-Oram syndrome but arise from different mutations. + Holt-Oram syndrome may not be suspected until cardiac problems manifest. Holt-Oram syndrome is a rare genetic disorder that causes heart problems and abnormal bone development in the upper limbs. These symptoms can manifest in myriad ways ranging from abnormalities that can only be detected via x-ray to a total absence of forearm bones Holt-Oram syndrome (HOS) is characterized by mild-to-severe congenital cardiac defects and skeletal abnormalities of the upper limbs. The most common cardiac disorder is an ostium secundum atrial septal defect (ASD), followed by ventricular septa
Holt-Oram syndrome: A genetic syndrome characterized by the combination of heart disease and malformations of the upper limb. The heart defect is usually an atrial septal defect and, less often, a ventricular septal defect (VSD), although other cardiovascular malformations have been reported.

It is most commonly found in upper arms, but can be found throughout the entire body. Anybody can be affected by this defect. It is passed through genes, so there is no preventing it; 1 in 100,000 will have this defect.
