How does a person inherit progeria?
How does a person inherit Progeria? Progeria is an extremely rare chromosomal disease. Progeria affects only 1 in 4-8 million births so it is incredibly rare. Progeria is a sporadic autosomal dominant disease, meaning it is random and if there is a mutation in favor of Progeria, the child that's DNA has undergone this mutation will definitely ...
What is the inheritance pattern of progeria?
Pattern of inheritance of non-classical progeria is most probably autosomal recessive. The cause of HGPS is an abnormally formed Lamin A, either directly by a mutated LMNA gene, or through abnormal posttranslational processing (ZMPSTE24 gene mutations).
Is there a cure for progeria?
There's no cure for progeria, but ongoing research shows some promise for treatment. Usually within the first year of life, growth of a child with progeria slows markedly, but motor development and intelligence remain normal. Signs and symptoms of this progressive disorder include a distinctive appearance:
What is the genetic cause of progeria?
Progeria is caused by a mutation (change) in the lamin A (LMNA) gene. This gene makes a protein that holds the nucleus of a cell together. Because of the change in the gene, the protein becomes defective. This makes the nucleus unstable, which is believed to cause the premature aging process.
Is progeria passed down from parent to child?
Is Progeria passed down from parent to child? HGPS is not usually passed down in families. The gene change is almost always a chance occurrence that is extremely rare. Children with other types of “progeroid” syndromes which are not HGPS may have diseases that are passed down in families.
How is progeria passed on?
Inheritance. Hutchinson-Gilford progeria syndrome is considered an autosomal dominant condition, which means one copy of the altered gene in each cell is sufficient to cause the disorder.

Progeria is diagnosed based on the symptoms, a clinical exam, and may be confirmed by the results of genetic testing. [1]
How do people with progeria die?
Most people with progeria die in their teens from a heart attack or stroke. Progeria is caused by a genetic variant in the LMNA gene. This variant usually arises as a new change in the genetic material and is not inherited from a parent. Diagnosis is based on the symptoms, clinical exam, and may be confirmed by the results of genetic testing.
What is the cause of Hutchinson-Gilford progeria?
DNA changes known as pathogenic variants are responsible for making genes work incorrectly or sometimes, not at all. One specific variant in the LMNA gene is responsible for most of the cases of Hutchinson-Gilford progeria. [1]
