Yes, there are various types of Dwarfism. The most common form of dwarfism, achondroplasia occurs in about one out of 26,000 to 40,000 babies and is evident at birth. They have a relatively long trunk and shortened upper parts of their arms and legs. Other features of achondroplasia include: a large head with a prominent forehead; a flattened bridge of the nose; protruding jaw; crowded and misaligned teeth; forward curvature of the lower spine; bowed legs; flat, short, broad feet and double-jointedness, among others. A less common form of dwarfism, Spondyloepiphyseal dysplasias (SED), refers to a group of conditions characterized by a shortened trunk, which may not become apparent until a child is between ages 5 and 10. Other features can include: club feet, cleft palate; severe osteoarthritis in the hips; weak hands and feet and barrel-chested appearance. A rare form of dwarfism, diastrophic dysplasia occurs in about one in 100,000 births. People who have it tend to have shortened forearms and calves (this is known as mesomelic shortening). Other signs can include deformed hands and feet, limited range of motion, cleft palate and ears with a cauliflower appearance.
