Understanding Hypothyroidism due to deficient transcription factors involved in pituitary development or function

Hypothyroidism due to deficient transcription factors involved in pituitary development or function is a type of central congenital hypothyroidism.

It is a permanent thyroid hormone shortage present from birth. It is caused by disorders in how the pituitary gland develops or works. It usually shows in infancy.

Signs & symptoms

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

  • Fatigue and lethargy
  • Constipation
  • Feeding difficulties in infancy
  • Slow growth
  • Delayed development
  • Facial puffiness and large tongue

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.

    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.
