Loeys-Dietz Syndrome

Loeys-Dietz Syndrome also known as LSD is a autosomal dominant syndrome which is caused by a mutation in the genes encoding for transforming growth factor. It is inherited from the persons parents and since it is autosomal dominant only one parent needs to have the syndrome to pass it on. To diagnos LSD Doctors will check the patients family history, a physical exam, and do a genetic test to see if they have lsd.

Some of the symptoms of Loeys-dietz are,

1. Split uvula
2. Defects in heart and brain
3. Weak bones
4. skin changes
5. Defects of the spine and chest
6. far apart eyes (picture to right)

Muddiest Point

For me the muddiest point has been the most 0f the notes because I get confused with some of the terms and stuff. I use to know some of this stuff but I forgot. The food web and the energy pyramid are also confusing but I just need to study them.
