Overview
Non-syndromic amelia is a rare congenital condition in which a person is born with one or more limbs completely missing. The term 'amelia' comes from the Greek word meaning 'without a limb.' The word 'non-syndromic' means that the missing limb occurs on its own, without other major birth defects or a recognized genetic syndrome. This sets it apart from syndromic forms of amelia, where missing limbs happen alongside other health problems such as heart defects, facial differences, or organ abnormalities. Amelia is detected at birth or sometimes earlier through prenatal ultrasound imaging. The condition can affect one limb (such as one arm or one leg) or multiple limbs. Because the limb is entirely absent, the condition affects mobility, daily activities, and independence depending on which and how many limbs are involved. There is no cure that can restore a missing limb. Treatment focuses on helping the individual function as well as possible. This includes prosthetic limbs (artificial limbs), physical therapy, occupational therapy, and adaptive devices. Many people with non-syndromic amelia live full, active lives with appropriate support. Advances in prosthetic technology, including myoelectric and 3D-printed prostheses, have greatly improved quality of life. Psychological support is also important, especially during childhood and adolescence, to help with self-image and social adjustment.
Key symptoms:
Complete absence of one or more arms or legs at birthDifficulty with mobility if a leg is missingDifficulty with grasping and hand tasks if an arm is missingChallenges with balance and coordinationNeed for assistive devices or prostheticsPossible phantom limb sensations in some individualsMuscle and joint differences in the remaining limbs due to compensatory use
Variable

Begins at or shortly after birth (first 4 weeks)
