Living with Tetraamelia-multiple malformations syndrome

An extremely rare condition with missing limbs and differences in many body systems from birth.

Understanding Tetraamelia-multiple malformations syndrome

Tetraamelia-multiple malformations syndrome is an extremely rare condition present from birth with absence of all four limbs and other major differences in the body.

Other body parts often affected include the head, face, eyes, skeleton, heart, lungs, anus, urinary and genital organs, and brain. GARD says it has been described in fewer than 20 people, mainly of Middle Eastern descent.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Absence of the arms
  • Absent or small lungs
  • Small eyes (microphthalmia)
  • No anal opening (anal atresia)
  • Cleft of the mouth (orofacial cleft)
  • Heart wall differences

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include bone and joint specialists, eye disease specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
