<unk>  <unk>  is a genetic condition that affects several parts of the body. The most common features of this condition are an obstruction of the anal opening (imperforate anus), abnormally shaped ears, and hand malformations that most often affect the thumb. Most people with this condition have at least two of these three major features.
The prevalence of this condition is unknown, although one study estimated that it may affect 1 in 250,000 people. It is difficult to determine how frequently<unk>  occurs because the varied signs and symptoms of this disorder overlap with those of other genetic syndromes. It affects both males and females equally.  The condition was first identified in 1972.
