SNP Shot: Genomic Insights

Mucolipidosis III gamma is a slowly progressing condition impacting various bodily systems. The characteristic signs and symptoms generally manifest around the age of 3.

Individuals affected by mucolipidosis III gamma experience slow growth leading to short stature. Joint stiffness and dysostosis multiplex, identifiable as multiple skeletal abnormalities on X-rays, are also common. Many develop osteoporosis, a condition characterized by reduced bone mineral density, increasing fracture risk. Osteoporosis and worsening joint issues contribute to pain in mucolipidosis III gamma patients, intensifying with age.

Heart valve defects and slight corneal clouding are frequently observed in individuals with mucolipidosis III gamma. Facial features may become subtly thickened or "coarse" as they age. A small fraction may have mild intellectual disability or learning difficulties. While survival into adulthood is typical, life expectancy may be reduced in individuals with mucolipidosis III gamma.

Inheritance:

Mucolipidosis III gamma follows an autosomal recessive inheritance pattern. This means that both copies of the responsible gene in each cell must carry a mutation for the condition to develop. Parents of an affected individual each carry one mutated gene copy but usually don't exhibit any symptoms of the condition themselves.
