DNA chart may give clue to the origins of diseasesn - Look at Psorasis

In my previous article I have briefly mentioned that certain kind of skin disease will passed on by generation i.e. psoriasis & eczema.

One thing I don't understand is that the psoriasis normally happen in an interval of generation gap. my research have found that sometime the Grand pa generation have psoraisis then the father & uncle generation would not be having it. Then the son or daugther generation , one of the member would have the disease.

But these is for sure is of the DNA & the gene that come to effect.

Those who have the Psorasis must avoid to have stress,

Not to Drink Beer or Alcohol,

Not to eat too much Prawn

Not to eat Crab, So as to prevent the disease to turn bad.

DNA chart may give clue to the origins of diseases
By Mark Henderson
A GENETIC map that charts the way DNA varies across three racial groups will illuminate the origins of health problems as diverse as heart disease and mental illness, scientists said yesterday.

The completion of the mapping project by Perlegen Sciences, a company based in California, will help researchers to pinpoint genetic variants that contribute to disease and promises to lead to more effective, tailor-made medical treatments.

The study, published yesterday in Science and also presented to the meeting, is the first of its kind to be made public.

It has identified 1.58 million changes in single “letters” of DNA among 71 individuals of Caucasian, African-American and Chinese-American backgrounds.

Analysis of these variants, known as single nucleotide polymorphisms, or SNPs (pronounced “snips”), will enable scientists to identify patterns that work together to trigger illness, or which affect how individual patients are likely to respond to particular drugs.

While 99.99 per cent of the human genome is shared by all people, millions of mutations in single DNA letters have accumulated during our evolution. Some of these SNPs occur in patterns particular to certain populations that share common recent ancestry; others are peculiar to individuals. They account for some of the differences between both people and ethnic groups, affecting traits as diverse as blood pressure and eye colour.

Geneticists believe that mapping and understanding SNPs will be critical to harnessing the medical benefits of the Human Genome Project.

Donald Kennedy, the editor-in-chief of Science, said: “This will provide an invaluable resource for genetic research to improve human health.”
