Flashcards

Tay-Sachs disease

A genetic disorder caused by the accumulation of a fatty substance called ganglioside GM2 in the brain due to a deficiency of the enzyme hexosaminidase A, which is involved in lysosome function.

McArdle disease

A rare genetic disorder characterized by the accumulation of glycogen in muscles due to a deficiency of the enzyme glycogen phosphorylase, which is involved in breaking down glycogen in mitochondria.

Kearns-Sayre Disease

A rare genetic disorder that affects the mitochondria, leading to a variety of symptoms including heart problems, vision loss, and muscle weakness.

Amyotrophic lateral sclerosis (ALS)

A neurodegenerative disease that affects motor neurons, leading to progressive muscle weakness, paralysis, and eventually death.

Study Notes

Diseases Associated with Organelle Dysfunction

Tay-Sachs Disease: Linked to lysosomes, which are membrane-bound sacs containing enzymes.
McArdle Disease: Stems from mitochondrial malfunction.
Kearns-Sayre Disease: Affects mitochondria.
Amyotrophic Lateral Sclerosis (ALS): Involves a problem with intermediate filaments, specifically neurofilaments.
