Living with Grange syndrome
A rare condition affecting the blood vessels, with narrowed or blocked arteries, plus bone, finger, and heart differences.
Understanding Grange syndrome
Arteries that supply the kidneys, brain, and heart may be narrowed (stenosis) or blocked (occlusion). Narrowed kidney arteries can cause chronic high blood pressure, and blocked brain arteries can cause a stroke. Other features can include short or fused fingers and toes, fragile bones, and learning disabilities. Most people also have heart defects present from birth. It is usually noticed in childhood.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Narrowed arteries (arterial stenosis)
- High blood pressure
- Fused fingers or toes (syndactyly)
- Bones that break easily
- Learning disabilities
- Heart valve leakage (aortic regurgitation)
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
Diagnosis
- 1Talk with your doctor
Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
- 2See a specialist
Specialists who may be involved include autoimmune and inflammatory disease specialists, bone and joint specialists, brain and nervous system specialists and genetic specialists.
- 3Consider genetic testing
Changes in YY1AP1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
Care & treatment
- Care team
- autoimmune and inflammatory disease specialists (rheumatologists); Bone and joint specialists (orthopedists or orthopedic surgeons); Brain and nervous system specialists (neurologists); Genetic specialists (geneticists)
- Expert care
- Ask about multidisciplinary care centers for rare conditions
- Treatment
- GARD doesn't list specific treatments for this condition. Your care team will tailor care to your symptoms.
- Research

General information, not medical advice. Your care team makes the decisions.
Everyday life
