Living with Hypothyroidism due to TSH receptor mutations

A lasting underactive thyroid present from birth, because the thyroid does not respond to TSH.

Understanding Hypothyroidism due to TSH receptor mutations

Hypothyroidism due to TSH receptor mutations is a type of primary congenital hypothyroidism caused by thyroid resistance to TSH.

It is a permanent thyroid hormone shortage present from birth. The thyroid does not respond well to thyroid-stimulating hormone (TSH). It is seen in newborns and infants.

Signs & symptoms

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

  • Underactive thyroid from birth
  • Low thyroid hormone (T4)
  • High TSH
  • Prolonged jaundice in newborns
  • Reduced iodine uptake

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. Consider genetic testing

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

Care & treatment
