Living with Achalasia microcephaly syndrome

An extremely rare genetic condition with a small head, learning challenges, and swallowing trouble from achalasia.

Understanding Achalasia microcephaly syndrome

Achalasia microcephaly syndrome is an extremely rare genetic condition that combines a small head, intellectual disability, and achalasia.

Achalasia is a swallowing problem in the food pipe. It brings coughing, trouble swallowing, vomiting, slow weight gain, and aspiration (food or liquid going into the airway), starting in infancy or early childhood. One case reported antenatal exposure to Mefloquine. GARD lists onset as newborn.

Signs & symptoms

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

  • Small head size (microcephaly)
  • Intellectual disability
  • Achalasia (trouble swallowing)
  • Slow growth
  • Prominent nose
  • Large lower jaw

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 digestive 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
InheritanceAutosomal Recessive

GARD says changes in genes (also called variants) cause this condition. It is autosomal recessive, so a child inherits a changed copy of the gene from each parent.
