Living with Fontaine progeroid syndrome

A rare genetic syndrome present from birth with early closing of skull bones, an older-looking appearance, and distinctive facial features.

Understanding Fontaine progeroid syndrome

Fontaine progeroid syndrome, also called Gorlin-Chaudhry-Moss syndrome, is a genetic condition that affects many parts of the body from birth or infancy.

It causes early closing of skull bones (craniosynostosis), which affects head and face shape. Facial features can include a sunken midface and small eyes. A lack of fat under the skin, with thin, wrinkled skin and visible veins, gives a look of premature aging. Extra hair growth, short end bones of the fingers and toes, and dental problems also occur.

Signs & symptoms

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

  • Early skull bone closing (craniosynostosis)
  • Small head size
  • Sunken midface and small lower jaw
  • Thin, loose skin that looks older than age
  • Extra hair growth (hypertrichosis)
  • Heart differences

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 autoimmune and inflammatory disease specialists, bone and joint specialists, genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in SLC25A24 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    National Foundation for Ectodermal Dysplasias may keep lists of experts for this condition.

Does the heart need regular checks?

Quick facts

InheritanceAutosomal Dominant
GenesSLC25A24

Changes in the SLC25A24 gene cause it. It is autosomal dominant, which means one changed copy of the gene is enough.
