Living with Isolated congenital growth hormone deficiency

A hormone condition in which the body makes very little growth hormone, leading to slow growth and short stature.

Understanding Isolated congenital growth hormone deficiency

Isolated congenital growth hormone deficiency is a condition caused by a severe shortage or absence of growth hormone.

Growth hormone is a protein needed for normal growth of bones and tissues. Without enough, children grow slowly and are unusually short. It is usually clear by early childhood. There are four types, which differ in how severe they are, which gene is involved, and how they are inherited. In type II, nearly half of people have an underdeveloped pituitary gland, the gland that makes growth hormone.

Signs & symptoms

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

  • Short stature
  • Slow growth (growth delay)
  • Delayed bone growth (skeletal maturation)
  • Delayed puberty
  • Doll-like face with a prominent forehead
  • High-pitched voice

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 genetic specialists and hormone specialists.

  3. Ask which tests can help

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

  4. Connect with expert centers

    Raymond A. Wood Foundation and Pituitary Network Association may keep lists of experts for this condition.
