1 Progeria Mike Choi

2 How does Progeria occur? 90% of children with Progeria have a mutation on the gene that encodes Lamin A, a protein that holds the nucleus of the cell together.

3 History Progeria was first described in 1886 by Jonathan Hutchinson and also described independently in 1897 by Hastings Gilford.

4 Can Progeria be passed to future generations? It cannot be passed to future generations because it is due to a rare gene change which happens purely by chance.

5 Type of Mutation Mutation in the LMNA gene on chromosome 1 The mutated form of lamin A is commonly known as progerin.

6 Where does it occur? Lamin A The LMNA gene codes for two proteins – lamin A and lamin C In HGPS, the LMNA gene produces abnormal form of the lamin A protein

7

8 phenotypic effects to the human body Growth failure Loss of body fat Loss of hair Aged-looking skin Stiffness in the joints Hip dislocation Heart disease

9 Diagnosis aging skin, loss of hair, stiffness of joints…etc can be examined through a genetic test

10 Treatment hope No treatment known so far Mostly focuses on reducing complications like heart bypass surgery or low-dose aspirin
