Living with Aprosencephaly cerebellar dysgenesis
A rare genetic condition in which major parts of the brain do not form before birth.
Understanding Aprosencephaly cerebellar dysgenesis
The telencephalon (the largest part of the brain) is absent and other parts, including the midbrain and cerebellum, are severely affected. Some people also have differences in the hands and feet. It is seen during pregnancy.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Absent or poorly formed parts of the brain
- Abnormal cerebellum (cerebellar dysplasia)
- Small lower jaw (micrognathia)
- Clubfeet
- Early closing of skull bones (craniosynostosis)
- Split uvula (bifid uvula)
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
Diagnosis
- 1Talk with your doctor
Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
- 2See a specialist
Specialists who may be involved include brain and nervous system specialists and genetic specialists.
- 3Ask which tests can help
Your care team will decide which exams and tests can confirm the diagnosis.
Care & treatment
- Care team
- Brain and nervous system specialists (neurologists); Genetic specialists (geneticists)
- Expert care
- Ask about multidisciplinary care centers for rare conditions
- Treatment
- GARD doesn't list specific treatments for this condition. Your care team will tailor care to your symptoms.
- Research
- Clinical trials and observational studies may be options. See the research section below.
General information, not medical advice. Your care team makes the decisions.
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
Quick facts
GARD says changes in genes (also called variants) cause this condition. It is autosomal recessive, meaning a child inherits a changed copy of the gene from each parent.
Also known as: aprosencephaly and cerebellar dysgenesis
