1. PROGERIA
By: Monica Cruz

2. How it occurs
Mutation in the gene that encodes LMNA (produces lamin A protein /imp. in the membrane)
Lamin A- known as a filament protein and a fibrous protein . It provides stability and strength to cells in the nucleus.
Out of 664 amino acids coding for this protein only 50 do during mutation.
When there's something wrong with this protein it makes nucleus unstable.
Lamin A mutation

3. Background Info. Known as Hutchinson-Gilford Progeria Syndrome (HGPS)
Progeria is a genetic disorder that causes children to age rapidly, beginning in their first two years of life.
The name is Greek and means “ prematurely old.“
single dominant allele
It effects 1 in 8 million newborns worldwide
The condition is rare/ Genetic disorder

4. more info. since 1886, only about 130 cases have been found.
A Progeria body ages about 10 times faster than normal
first described in England in 1886 by Dr. Jonathan Hutchinson.
Dr. Hastings Gilford studied the disorder in 1904
Usually die b/c of a heart attack or stroke
live only up to 13 years

5. Diagnosis
The diagnosis is made during the first or second year with symptoms that include skin changes and failure to gain weight.
It is also found that Progeria patients may have the chemical hyaluronic acid found in their urine.
Hyaluronic acid – helps regulate the cell growth and it’s a type of polysaccharide
Prenatal testing for progeria is possible using amniocentesis. Then the fetal DNA is examined for genetic abnormalities.

6. Treatments There's no cure
Cardiac care ,nutritional, and physical therapy.
low dosage of aspirin is used as an attempt to delay atherosclerosis
Atherosclerosis- blood vessel walls thicken
