Living with Temple syndrome

A rare genetic condition with feeding trouble, slow growth, low muscle tone, and early puberty.

Understanding Temple syndrome

Temple syndrome is a rare genetic condition that affects growth and development.

Babies and children may have feeding trouble, growth delays, and low muscle tone. People can have mild intellectual disability and reach milestones like crawling or walking later. Facial features may include a broad forehead, a short nose, downturned mouth corners, and a small jaw. Children may gain weight easily, start puberty early, and have small hands and feet.

Signs & symptoms

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

  • Feeding difficulties in infancy
  • Low muscle tone
  • Slow growth and short stature
  • Delayed speech and motor skills
  • Early puberty
  • Small hands and feet

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 brain and nervous system specialists, genetic specialists and hormone specialists.

  3. Ask which tests can help

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