Phocomelia is a malformation of the limbs. It consists of underdevelopment or complete absence of long bones with the presence of feet or hands. These are directly connected to the trunk. The condition is commonly referred to as "seal limbs". Ear and nose defects are also very common in patients. The search for direct causes of phocomelia is still ongoing. Scientists and doctors are paying particular attention to genetic birth defects and the use of thalidomide during pregnancy.
