Holt-Oram Syndrome: Hands are the Clue to the Diagnosis

Holt-Oram syndrome or heart-hand syndrome consists of phenotypic and genotypic abnormalities. It is characterized by abnormalities of upper limbs and congenital cardiac defects. It is an autosomal dominant disorder due to a mutation in TBX5 gene located on chromosome 12, but sporadic cases have also been reported. We describe a 26-year-old female with a history of shortness of breath for 5 years. She had bilateral hand deformities, and on evaluation, found to have ostium secundum atrial septal defect which is common cardiac defect in Holt-Oram syndrome.
