Living with Developmental delay with short stature, dysmorphic facial features, and sparse hair 1

A rare genetic syndrome with developmental delay, short stature, distinct facial features, and sparse hair.

Understanding Developmental delay with short stature, dysmorphic facial features, and sparse hair 1

Developmental delay with short stature, dysmorphic facial features, and sparse hair 1 is a rare genetic syndrome present from birth.

Features include distinct facial features, short stature, sparse eyebrows, eyelashes, and scalp hair, small toenails, developmental delay, and intellectual disability. Some people have brain malformations and mild kidney problems. GARD lists onset during pregnancy or in the newborn period.

Signs & symptoms

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

  • Global developmental delay
  • Distinct facial features
  • Small cerebellar vermis or Dandy-Walker malformation
  • Kidney differences
  • Flat feet
  • Fingers or toes that stay bent (camptodactyly)

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 and genetic specialists.

  3. Consider genetic testing

    Changes in DPH1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
