Living with GNPTG-mucolipidosis
A very rare inherited condition with slow growth in early childhood, stiff and painful joints, and changes in facial features over time.
Understanding GNPTG-mucolipidosis
It is most commonly seen in the Middle East. It involves slow growth in early childhood, stiffness and pain in the shoulders, hips, and finger joints, and thickening or rounding of the face over time. Thinking skills are usually normal or slightly affected. Some people gradually lose vision from retinitis pigmentosa. Symptoms progress more slowly than in other types of mucolipidosis. Late symptoms may include heart and lung problems.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Stiff, painful joints
- Finger joint contractures and claw hand
- Nearsightedness (myopia)
- Flat feet and knock knees
- Short neck
- Swayback
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
