Transcript of Progeria

Progeria A project by: Jaynelyn Lemoncito
Block 3
Who dicovered Progeria and what is it? Is there any type of treatment available for Progeria? How common is this disorder? Do some groups have Progeria more than others? Hutchison- Gilford Progeria Syndrome (Progeria or HGPS) was discovered and found it's name by two English doctors. The doctors are Dr. Jonathan Hutchison and Dr. Hastings Gilford in the late 1800's; however, the gene for Progeria was not found until 2003. Progeria is a rare and fatal genetic condition that ages children faster and changes their physical appearance. <runkle-science.wikispaces.com/Hutchison-Gilford+Progeria+Syndrome> 90% of children that have Progeria has a mutation on their gene. There is one that has a gene that encodes Lamin A which is a protein that holds the nucleus together. Then, there is the defective Lamin A which makes the nucleus weak. <http://www.progeriaresearch.org/about_progeria.html> <http://www.medicalnewstoday.com/articles/146746.php> There is no type of heredity in Progeria. Researchers say that it is due to a rare gene change. <http://www.medicalnewstoday.com/articles/146746.php> What are the symptoms and signs or Progeria? What is the life expectancy for someone with Progeria? Symptoms of Progeria:
~Slowed growth
~Below average weight
~Alopecia on the
eyebrows, eyelashes,
and head (hairloss)
~Scleroderma (hardening
and tightening on skin)
~Stiff joints
~Hip dislocation
~Irregular heartbeat
~Micrognathia (small
lower jaw)
Etc. The average life expectancy for somebody who has Progeria is about thirteen years. Some could die at a younger age and some could live up to twenty years old or longer. Haley Okines: 14 years old <http://www.mayoclinic.com/health/progeria/DS00936/DSECTION=symptoms> <http://www.cnn.com/HEALTH/library/progeria/DS00936.html> Sadly, there is no type of cure for Progeria. Some people would try coronary artery bypass surgery or angioplasty (dilation of cardiac arteries) to slow the progression of cardiovascular disease. Other therapies may ease the signs and symptoms also <http://www.mayoclinic.com/health/progeria/DS00936/DSECTION=treatments-and-drugs> Progeria occurs in 1 of 4 of every eight million newborns. There is about 200 to 250 children living with Progeria worldwide. <http://www.progeriaresearch.org/progeria_101.html> Progeria affects both sexes equally and all races, but mostly children. <http://www.progeriaresearch.org/progeria_101.html> Some other facts about Progeria:
~For the child's first year
they seem normal but
then their growth rate
starts to slow down.
~Progeria is an extermely
rare disorder. Seth Cook: Passed away at 13 years old.
