Question 1

what is karyotyping?

Accepted Answer

Chromosome study: A karyotype is a visual presentation of the chromosomes present in each cell, usually derived from blood lymphocytes.  The cells are grown in tissue culture, then arrested in the stage of separation  (mitosis), then  dropped on a glass slide from about 2 feet, which breaks them open;  a dye is added to make stain them, a photo taken, then arranged into their 23 pairs, then studied for anomalies.

Question 2

what is the definition or description of: karyotyping?

Accepted Answer

See below: Karyotyping is a test to examine chromosomes in a sample of cells, which can help identify genetic problems as the cause of a disorder or disease. This test can:
•count the number of chromosomes
•look for structural changes in chromosomes

the test can be performed on almost any tissue, including:
•amniotic fluid
•blood
•bone marrow
•placenta.

Question 3

what happens if we assume that the vitiligo is generic disorder then can we check if it's a dominant, recesive and carrier etc. using karyotyping.?

Accepted Answer

Autoimmune: Vitiligo is usually considered an autoimmune problem. If you want to find out whether it is genetic, you will need to get a detailed history on family members with this problem.   I am not aware of any genetic markers uncovered thus far. Nonetheless if there has been no history of such a disorder among your immediate family members within 3 generations, genetic study would be meaningless.

Question 4

what is progeria?

Accepted Answer

Supportive care: This rare pattern of premature aging is seldom seen by primary care providers. Assessment and confirmantion of any such DX by a geneticist is imperitive. Most work with a team of specialists who can monitor the DX specific healthrisks & provide guidence for your local source of care.They can also help you find support groups & other parents in the same situation.

Question 5

what is the cause of progeria?

Accepted Answer

Most new mutations: Progeria is a self limited process with most recorded cases appearing as new mutations in families that have other normal children. There are rare sibships reported indicating an autosomal recessive form exists.Most don't survive their teens.

Question 6

what are the tests for progeria?

Accepted Answer

See below: The gene responsible for progeria has been identified (lamin a) in april 2003. A blood test can now be performed  progeria is due to a point mutation in this gene.  It is not usually passed down in families.  The gene change is a chance, rare occurrence.

Question 7

how can progeria be transmitted?

Accepted Answer

Most new mutations: Progeria is a self limited process with most recorded cases appearing as new mutations in families that have other normal children. There are rare sibships reported indicating an autosomal recessive form exists.Most don't survive their teens.

Question 8

what is progeria? can it be cured?

Accepted Answer

Most new mutations: Progeria is a self limited geneticnprocess with most recorded cases appearing as new mutations in families that have other normal children. There are rare sibships reported indicating an autosomal recessive form exists.Most don't survive their teens.There is no known cure.

Question 9

what are the symptoms of progeria?

Accepted Answer

Resources: Please check with the geneticist involved in your child's care. Also, the following website may be useful http://www.Progeriaresearch.Org/progeria_101.Html.

Question 10

what is progeria and what causes it?

Accepted Answer

Supportive care: This rare pattern of premature aging is caused by a random new genetic mutation. Assessment and confirmantion of any such DX by a geneticist is imperitive. Most work with a team of specialists who can monitor the DX specific healthrisks & provide guidence for your local source of care.They can also help you find support groups & other parents in the same situation.
