Living with Cognitive impairment - coarse facies - heart defects - obesity - pulmonary involvement - short stature - skeletal dysplasia syndrome

A genetic condition present from birth that affects learning, the heart, lungs, bones, growth and facial features.

Understanding Cognitive impairment - coarse facies - heart defects - obesity - pulmonary involvement - short stature - skeletal dysplasia syndrome

CHOPS syndrome is a condition present from birth that involves many body systems, including learning, the heart, lungs, bones and growth.

The name CHOPS stands for cognitive impairment, coarse facial features, heart defects, obesity, lung involvement, short stature and skeletal differences. Children often have intellectual disability and are slower to sit and walk. Many are born with a heart defect called patent ductus arteriosus, and some have other heart differences.

Signs & symptoms

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

  • Intellectual disability and delayed development
  • Heart differences, such as a hole between the lower heart chambers
  • Lung and breathing problems, including chronic lung disease
  • Small head size (microcephaly)
  • Acid reflux and feeding problems in infancy
  • Hearing loss

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 bone and joint specialists, brain and nervous system specialists, genetic specialists and heart and blood vessel specialists.

  3. Consider genetic testing

    Changes in AFF4 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
