Living with Pseudohypoparathyroidism type II

A form of pseudohypoparathyroidism in which the body resists parathyroid hormone, causing low calcium.

Understanding Pseudohypoparathyroidism type II

Pseudohypoparathyroidism type II (PHP2) is a form of pseudohypoparathyroidism in which the body resists parathyroid hormone (PTH).

It causes low calcium, high phosphate, and high PTH levels. Unlike other types, there are no Albright's hereditary osteodystrophy features, and Gs protein and urine cAMP response are normal. It can start at any time in life.

Signs & symptoms

Symptoms vary from person to person. GARD lists pseudohypoparathyroidism itself among the most common features, and these less common ones:

  • Low calcium with high phosphate
  • Muscle spasms
  • Pins and needles feeling
  • Spasms of the voice box (laryngeal dystonia)

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, hormone specialists and kidney 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

    HypoPARAthyroidism Association, Inc. may keep lists of experts for this condition.
