Living with Familial retinal arterial macroaneurysm

An inherited condition affecting blood vessels in the eyes and a narrowing near the heart's lung valve, starting in infancy or childhood.

Understanding Familial retinal arterial macroaneurysm

Familial retinal arterial macroaneurysm with supravalvular pulmonic stenosis (RAMSVPS) is a condition that affects blood vessels in the eyes and heart.

It usually shows up in infancy or childhood. Arteries in the retina develop small bulges (beading) and later larger bulges (macroaneurysms) that can burst and bleed, causing vision loss. People also have a narrowing just above the heart valve that sends blood to the lungs, which can cause shortness of breath, a fast heartbeat, tiredness, and swelling.

Signs & symptoms

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

  • Bulges in retinal arteries (macroaneurysms)
  • Narrowing of the pulmonic valve area
  • Fluid causing retinal detachment
  • Shortness of breath
  • Fast heartbeat and tiredness
  • Swelling in the face, feet, or belly

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 brain and nervous system specialists, eye disease specialists, genetic specialists and heart and blood vessel specialists.

  3. Consider genetic testing

    Changes in IGFBP7 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

InheritanceAutosomal Recessive
GenesIGFBP7

Changes in the IGFBP7 gene cause it. It is autosomal recessive, which means a child inherits a changed copy of the gene from each parent.
