Lysosomal Storage Diseases

- vacuum cleaners of the cell
![](https://i.imgur.com/camgLzX.jpg)
- child born without enzymes
Sphingosines
![](https://i.imgur.com/KnDj0CN.jpg)
- most diseases are ceramide derivative, all contain sphingosine, and are all sphingolipids

Fabry's
![](https://i.imgur.com/eXQaOFB.jpg)
![](https://i.imgur.com/xA9f5Xs.jpg)
- most are autosomal recessive
- lives well into 30s-50s

- later
- restrictive cardiomyopathy

- accumulate in vascular endothelial cells

Gaucher

![](https://i.imgur.com/WyqLnO8.jpg)
![](https://i.imgur.com/W4tDJRW.jpg)
- liver/spleen affected: macrophages live here
- avascular necrosis: ischemia of joints (large macrophages filled with sphingolipids obstruct vessels supplying joints)

- similar path with sickle cell: abnormal large cells clog up vasculatures
![](https://i.imgur.com/qYxp4hl.jpg)
- minimal CNS
- normal lifespan from enzyme replacement

Niemann-Pick
![](https://i.imgur.com/tzpr3kJ.jpg)
![](https://i.imgur.com/UeoTmB6.jpg)
- CNS symptoms more often than Gaucher

![](https://i.imgur.com/p3g9xmj.jpg)
- central artery occlusion: never in children
![](https://i.imgur.com/3Vw6Mrl.jpg)
- liver/spleen not part of Tay Sack disease
Krabbe
![](https://i.imgur.com/GPq12gl.jpg)
![](https://i.imgur.com/F9FtvJu.jpg)
- present very young
- only neuro, no liver, spleen
![](https://i.imgur.com/1yMgbzG.jpg)
Gangliosides
![](https://i.imgur.com/DIJn9nk.jpg)
- family of sphingolipids, gangliosides related
- neuro deficits
Tay Sach
![](https://i.imgur.com/BtXBx3Z.jpg)
![](https://i.imgur.com/fh3z6vc.jpg)
- eventually vegetative state and death
![](https://i.imgur.com/997LiNK.jpg)
![](https://i.imgur.com/MKNeFgw.jpg)
- similar to Krabbe because both related to myelin
- sofa, falling, sulfatides
![](https://i.imgur.com/1yLDDKe.jpg)
- sulfatides take up different colors
- similar symptoms with Krabbe
![](https://i.imgur.com/goXMIQH.jpg)
- Fabry and Gaucher: no weakness, both have enzyme replacement therapy, long life span
- Krabbe, Tay Sach: present as baby
Glycosaminoglycans
![](https://i.imgur.com/hWuzRuR.jpg)
- repeating sets of 2 sugar molecules

Hurler's
![](https://i.imgur.com/HJIMRad.jpg)
![](https://i.imgur.com/qCosdJF.jpg)
![](https://i.imgur.com/phUcYNJ.jpg)
- abnormal mucopolysaccharides: thick secretions
Hunter's
![](https://i.imgur.com/o3ggf2J.jpg)
- x linked recessive
- no corneal clouding
- behavior problems
I-Cell
![](https://i.imgur.com/D13aiww.jpg)
![](https://i.imgur.com/KGARQgZ.jpg)
- synthesized normally, problem with processing
