Living with Congenital insensitivity to pain with severe intellectual disability

A rare inherited condition from birth with no sense of pain, little response to soft touch and severe, non-worsening developmental delay.

Understanding Congenital insensitivity to pain with severe intellectual disability

Congenital insensitivity to pain with severe intellectual disability is a rare inherited nerve condition with no feeling of pain from birth.

People also do not respond to soft touch and have severe cognitive delay that does not get worse over time. Movement, behavior and strength are normal. Hot and cold sensing is kept.

Signs & symptoms

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

  • Not feeling pain
  • Not responding to soft touch
  • Severe global developmental delay
  • Repeated fractures
  • Self-injury
  • Eye problems such as corneal inflammation

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. Consider genetic testing

    Changes in CLTCL1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    The Foundation for Peripheral Neuropathy may keep lists of experts for this condition.
