What is it?
Retinitis pigmentosa is a disease of the eye where the cells of the retina make defective proteins. It is caused by mutations in the Retinitis Pigmentosa gene and this causes it to make flawed proteins that are needed for normal vision.
Why is it considered Y-Linked?
This is a gene on the Y chromosome, meaning that it can only be passed from an affected father to son because women do not have a Y chromosome. Traits inherited along this mode of inheritance are rare as the Y chromosome is small and does not contain much genetic information.
What are the symptoms?
Some symptoms that come as a result of Retinitis Pigmentosa include progessively losing eye sight. It first starts out with decreased night vision and then loss of peripheral and then blindess.
What treatments are available?
There are four ways to treat Retinitis Pigmentosa. The first including surgery on the eye where the fat tissues of the eye are put in the back of the eye as to revive the most important part of the eye. A second way to treat it is to "stimulate the balance of blood circulation in the eye" . Third, "create flexibilty and effectivness in the red blood cells of the eye." Last but not least, give medicine to stimulate the other treatments and help balance out the bad side effects that they may cause (retinitis-pigmentosa.com).
