Medical Definition of Hecht syndrome
Hecht syndrome: An inherited disorder that is transmitted as an autosomal dominant trait, in which short, tight muscles make it impossible to open the mouth fully or keep the fingers straight when the hand is flexed back. The small mouth creates feeding problems. The hands may be so tightly fisted that infants with Hecht syndrome crawl on their knuckles. Also known as trismus pseudocamptodactyly syndrome.
