Living with Neutropenia-monocytopenia-deafness syndrome

A genetic condition with low levels of certain white blood cells and hearing loss present from birth.

Understanding Neutropenia-monocytopenia-deafness syndrome

Neutropenia-monocytopenia-deafness syndrome is a genetic condition with low neutrophils and monocytes (white blood cells) and hearing loss present from birth.

People with this condition have low numbers of two kinds of white blood cells, neutrophils and monocytes, along with bone marrow that makes fewer of certain blood cells (myeloid marrow hypoplasia). They also have hearing loss from birth. GARD lists onset as newborn and infant years.

Signs & symptoms

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

  • Hearing loss from the inner ear (sensorineural hearing impairment)
  • Differences in neutrophils, a type of white blood cell
  • Differences in how the immune system works
  • Differences in the shape of macrophages (immune cells)

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 allergy and immune system specialists, ear, nose, and throat specialists and genetic specialists.

  3. Ask which tests can help

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

  4. Connect with expert centers

    Immune Deficiency Foundation may keep lists of experts for this condition.
