Mucolipidosis III alpha/beta is a systemic disorder impacting various bodily functions. The characteristic features of this condition usually become noticeable around the age of 3 and gradually intensify.

Affected individuals with mucolipidosis III alpha/beta exhibit impaired growth leading to short stature. Joint stiffness and dysostosis multiplex, identifiable as numerous skeletal irregularities on x-rays, are also common. A significant number of these individuals develop osteoporosis, a condition characterized by reduced bone density, increasing the risk of fractures. The combination of osteoporosis and progressive joint issues results in increasing bone pain for those with mucolipidosis III alpha/beta.

Heart valve problems and slight corneal clouding are frequently observed in people with mucolipidosis III alpha/beta. Their facial features may gradually become somewhat thickened or "coarse." Recurring ear and respiratory infections are also common. Approximately 50% of individuals with this disorder experience mild intellectual disability or learning difficulties. While those affected by mucolipidosis III alpha/beta generally live into adulthood, their lifespan may be reduced.

Inheritance:

The inheritance pattern of this condition is autosomal recessive. This means that both copies of the responsible gene within each cell must contain mutations for the condition to manifest. The parents of an individual with an autosomal recessive disorder each carry one copy of the mutated gene but usually do not exhibit any signs or symptoms of the condition themselves.
