Psoriasis and
Genetics
Researchers have recently decided that psoriasis is caused,
in part, by a genetic component. Those who suffer from this
irritating disease have the right combination of genes to send
their body into a zealous production of T-Cells. These cells,
which are necessary for repairing the skin after it has been
damaged, run rampant in those with this skin disease. The
layering of skin cell upon skin cell finally results in the
raised patches of reddened skin with the scaling white
tops.
Researchers are currently studying why some people develop
psoriasis while others do not. They feel that there must be
mistakes in the genetic code, chemical errors within the DNA
that result in an inaccurate amount or positioning of the
protein. It is thought that this skin disease occurs
in individuals who receive a unique combination of genes. This
combination may not be the same for all people who develop the
disease though.
The missing component in the way psoriasis works is the
precipitating factor that activates the genes. Although
researchers have identified some of these factors, they still
don’t understand how these work to turn on the damaged genes.
For example, everyone who experiences stress, has an infection,
or suffers damage to the skin does not develop this skin
disease. Only those with an unusual combination of genetic
material do.
Researchers have closed in on the genetic component of
psoriasis in the last decade. They have gone so far as to
identify genetic markers, sections of the DNA that can be
closely linked with this disease. More than ten markers have
been identified, and researchers now know that at least three
genes located on chromosome 17 are in some way associated with
the onset of psoriasis.
Once all of the genes are pinpointed, researchers hope to
find ways to deactivate the immune system’s production of cells
that plagues those with this disorder. This knowledge will lead
to new drugs and treatments to change this rogue activity that
leads to psoriasis.
An important part of this genetic mapping has come as a
result of the Human Genome Project. Another important source of
genetic material used in the research of psoriasis is the
National Psoriasis Victor Henschel Bio Bank. This is a huge
central collection bank for samples of genetic material and
cells of those who have had the various forms of psoriasis.
Scientists hope that this material will aid in finally finding
the key to helping those with this skin disease.

Psoriasis skin disorder can be
very difficult to live with. There may be home remedies
psoriasis may respond to. Psoriasis skin disorders are
unpleasant and persistent. New psoriasis medication may be
discovered as time goes by. How do you get psoriasis is a
question that is not easily answered.
