Cohen syndrome: evaluation of its cardiac, endocrine and radiological features.

Cohen syndrome (MIM no. 216550) is an autosomal recessive disorder with a typical clinical picture. Since the first report, most publications have represented single case reports. In this study, our aim was to describe cardiac, endocrine and radiological abnormalities in 22 Cohen patients of Finnish descent. Detailed investigations of the heart revealed the anatomy of the heart to be normal with no evidence for clinically significant mitral prolapse. However, a decreased left ventricular function with advancing age was identified. No significant endocrine abnormalities were found at the examination of pituitary, adrenal and thyroid function. The height was either normal or patients were moderately short (mean height standard deviation score (SDS) - 2) at all ages, associated, however, often with the marked kyphosis. Truncal obesity was seen in 4/22 patients. X-rays of the chest, lumbar and thoracic spine, long bones, ankles and metacarpophalangeal pattern profiles revealed kyphosis, scoliosis and calcaneo planovalgus as common features. Fingers of these patients were slender but short with a characteristic metacarpophalangeal pattern profile.
