The Holt-Oram syndrome or atriodigital dysplasia is an autosomal dominant disorder with near complete penetrance and variable expression, caused by mutations of the TBX5 gene (12q24.1), affecting one in 100.000 live births. Sixty percent of cases are familial and 40% sporadic. We present the case of a 24 years old male patient with a personal history of bilateral coxa vara surgically corrected on the right at the age of 8 years, complicated by osteochondritis, short stature (160 cm), underweight (37 kg, BMI 14.45 kg/square-cm), triangular face, micrognathia, down slanting palpebral fissures, hypertelorism, low set ears, scoliosis, narrow shoulders, shortened left arm, left thumb agenesia, limited supination, abnormal toes, hypoplastic muscles, atrial septal defect ostium secundum type, incomplete right bundle branch block, hypoacusia and normal intelligence.
