Living with Curly hair, ankyloblepharon, nail dysplasia syndrome

A rare condition with sparse, woolly, curly hair, eyelids stuck together at birth, and nail differences.

Understanding Curly hair, ankyloblepharon, nail dysplasia syndrome

Curly hair, ankyloblepharon, nail dysplasia syndrome is a rare condition of the hair, eyelids, nails, and skin (an ectodermal dysplasia).

It combines sparse, woolly, curly hair, eyelids that are stuck together (ankyloblepharon), and nail differences. Other features reported include a split tongue, lip pits, bands joining the lips, wide-set eyes, a flat nasal bridge, and a closed hymen. It is present from birth.

Signs & symptoms

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

  • Curly hair
  • Eyelids stuck together (ankyloblepharon)
  • Nail differences (nail dysplasia)
  • Cleft palate or split tongue
  • Missing adult teeth
  • Less sweating (hypohidrosis)

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 ear, nose, and throat specialists, genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in RIPK4 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

    National Foundation for Ectodermal Dysplasias and World Craniofacial Foundation may keep lists of experts for this condition.
