Living with Cervical hypertrichosis-peripheral neuropathy syndrome

A rare genetic condition with extra hair on the front of the neck from birth and nerve damage affecting feeling and movement.

Understanding Cervical hypertrichosis-peripheral neuropathy syndrome

Cervical hypertrichosis-peripheral neuropathy syndrome is a rare genetic condition with extra hair on the front of the neck from birth and nerve damage that affects sensation and movement.

Other features may include retina differences, spina bifida, a curved spine, and a bent big toe. One person had developmental delay. GARD notes there have been no further descriptions in the medical literature since 1993. It starts in childhood.

Signs & symptoms

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

  • Extra hair over the body
  • Open skin sores (skin ulcers)
  • Bone infection (osteomyelitis)
  • Inflamed tissue around bones (periostitis)
  • Dandy-Walker malformation (a brain difference)

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, genetic specialists and skin, hair, and nail specialists.

  3. Ask which tests can help

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