Transcript of Progeria
• Caused by a mutation in the
gene LMNA (necessary for
producing proteins that
provide stability &
strength to the cells)
• When LMNA is mutated, an irregular
version is produced, called progerin, which attaches to a molecule called farnesyl group to cause progeria
• This disrupts the shape of the cell membrane & its fuction, leading to premature aging. • Loss of eyebrows and eyelashes, and hair
• Head large for the size of the face
• Loss of muscles and body fat
• Wrinkled, scaly, dry skin
• Delayed tooth formation
• High pitched voice
• Stiffness in joints
• Short stature
• Pinched nose
• Bulging eyes Treatments • No cure
• Several effective treatments
• Progeria Research Foundation found an effective drug that greatly improved the conditions.
• FTI called Lonafarnib:
- helps gain necessary weight
- acquires better hearing, improve bone structure
- increases flexibility of blood
vessels Causes Did You Know... The Effects of Lonafarnib Treatment • Jonathan Hutchinson and Hastings Gilford discovered progeria in 1886.
• There is another type of progeria called, "Werner's Syndrome."
• There is a 1 in 8 million chance of contracting progeria.
• Children with progeria age 6 to 8 times faster than normal people.
• The oldest victim of progeria lived to the age of 29. • Will have normal appearance at birth.
• Growth dramatically stops & symptoms start to appear within a year.
• Most die around the age of 8 to 20, averagely at 13. What Happens Leon Botha Works Cited Kalumuck, Karen E., and Nancy A. Piotrowski. "Progeria." Magill's Medical Guide. Ed.
