Neuronal ceroid lipofuscinosis (NCL) is a group of rare inherited neurological disorders causing the accumulation of lipofuscin in nerve cells, leading to progressive neurodegeneration, vision loss, and motor and cognitive impairments.

Pycnodysostosis is a rare genetic bone disorder characterized by increased bone density and hardening, leading to short stature, skeletal deformities, brittle teeth, and potential growth and mobility issues.

Sphingolipidosis is a group of inherited disorders affecting the breakdown of sphingolipids, leading to their accumulation in nerve cells and organs, causing neurological issues, developmental delays, and degenerative diseases.

Aplasia of lacrimal and salivary glands with chorea and liver dysfunction syndrome is a rare genetic disorder characterized by dry eyes due to reduced tear secretion, involuntary choreiform movements, and liver function abnormalities.

Alpha-1 antitrypsin deficiency is a genetic disorder causing low levels of this protein, leading to lung damage and liver diseases, such as emphysema and cirrhosis, especially in smokers or those with chronic infections.

Dominant hereditary myolysis is a genetic muscle disorder caused by structural or functional muscle weakness, leading to recurrent episodes of muscle breakdown or weakness, especially after exertion or infection.
