Living with Fetal akinesia-cerebral and retinal hemorrhage syndrome

A rare condition affecting muscles before and at birth, with little movement in the womb, weak muscles, stiff joints and bleeding in the brain and eyes.

Understanding Fetal akinesia-cerebral and retinal hemorrhage syndrome

Fetal akinesia-cerebral and retinal hemorrhage syndrome is a rare congenital muscle condition that begins before birth.

Babies move less than usual in the womb, and there may be extra amniotic fluid. After birth they have very low muscle tone with breathing problems, absent reflexes, and stiff joints (contractures). Thin ribs and bones, bleeding in the brain or the eyes, and low birth weight can also occur.

Signs & symptoms

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

  • Little movement in the womb
  • Extra amniotic fluid (polyhydramnios)
  • Very low muscle tone (hypotonia)
  • Breathing problems
  • Stiff joints (contractures)
  • Bleeding in the eyes or brain

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 and genetic specialists.

  3. Consider genetic testing

    Changes in DNM2 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

Everyday life

Living with a rare condition is easier with support.

  • Connect with rare disease patient organizations for support
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Should we have genetic testing for the DNM2 gene?
What breathing and feeding support is available?
What is the chance of this happening in another pregnancy?

Quick facts

Symptoms usually startNewborn and as an Infant
InheritanceAutosomal Recessive
GenesDNM2

Changes in the DNM2 gene cause it. It is autosomal recessive, which means a child inherits a changed copy of the gene from each parent.
