Living with GMS syndrome

An extremely rare syndrome with eye drainage differences, intellectual disability, short stature, and a small head, seen in one family.

Understanding GMS syndrome

GMS syndrome is an extremely rare syndrome with eye, learning, and growth differences, seen in one family to date.

It involves goniodysgenesis (a difference in the eye's drainage area), intellectual disability, and short stature. People also have a small head (microcephaly), short nose, and small hands and ears. GARD says there have been no further descriptions in the literature since 1992. It is noticed in the newborn period.

Signs & symptoms

Symptoms vary. GARD lists these among the most common:

  • Small head size (microcephaly)
  • Intellectual disability
  • Feeding difficulties in infancy
  • Low-set ears
  • Flat nasal bridge
  • Born early (premature birth)

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, eye disease specialists and genetic specialists.

  3. Ask which tests can help

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