Living with Bonnemann-Meinecke-Reich syndrome

An extremely rare genetic syndrome with brain, growth, and development differences, described in only two families.

Understanding Bonnemann-Meinecke-Reich syndrome

Bonnemann-Meinecke-Reich syndrome is an extremely rare genetic syndrome with brain disease in the first year of life and delayed development.

It has been described in two families, each with two affected siblings. Features include mild facial differences, early fusion of skull bones (craniosynostosis), short stature from low growth hormone, intellectual disability, stiffness, unsteadiness, and retinal changes. There have been no new reports since 1991.

Signs & symptoms

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

  • Short stature
  • Mild intellectual disability
  • Muscle stiffness (spasticity)
  • Small head (microcephaly)
  • Calcium deposits in the brain
  • Enlarged fluid spaces in the brain (ventriculomegaly)

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. Ask which tests can help

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

Quick facts

Symptoms usually startNewborn and as an Infant
InheritanceAutosomal Recessive

Changes in genes cause this condition. An autosomal recessive pattern has been suggested, which means a child would inherit a changed copy of the gene from each parent.
