** The picture on the left is an ear drum ** ** of someone who has Usher Syndrome. ** This specific condition is categorized as deafness, the progression of vision lost, and\or complete blindness. The loss of vision is caused by a disease known as Retinitis Pigmentosa. Retinitis Pigmentosa cause the light-sensitive tissue in the back of the eye to slowly continue to deteriorate, evidently this disease does not cause a person to go completely blind.
 * What is Usher Syndrome? **

**How many different types are there, and what are the symptoms of these types?**


 * __ Type 1 __** : Individuals who have type one Usher Syndrome tend to either be born deaf or lose most hearing by age one, lose of eye sight during child hood is caused by Retinitis Pigmentosa, and problems with the inner ear affect balance; results in child sitting independently and walking late than usual.
 * __ Type 2: __** Individuals who have type two are more commonly to have loss of hearing from birth and during adult hood start to gradually lose eye sight. The hearing lose could affect high tones on a mild to severe scale. Children who are affected by Usher Syndrome have difficulty hearing low and high tones. This type varies on how severe the condition is in the family. Children with this type do not sit independently or walk later that than usual.
 * __ Type 3: __** Individuals who have type three show signs of gradual loss of hearing with in the first few decades of living. Children who are born with type three Usher Syndrom are not born deaf, they have normal hearing. When the child is around their adolescent age they will begin to experience loss of hearing and loss of vision, after the child knows how to speak in full sentences. Many people with type three Usher Syndrome will experience uneven balance due to inner ear problems, but results may vary.


 * Common Treatments/ Help to control Usher Syndrome: **

-No treatment is yet to be found, but identifing the disease early enough in age is very vital. In this case the proper education, mobility training, learning sign language, learning to read braille, auditory training- the process in introducing different frequencies to people who are sensitive to different sound frequencies, or low- vision services- help utilize the persons remaining vision to its fullest potential. These are a variety of ways to make Usher Syndrome slightly easier to cope with.


 * What chromosome is effected by this disease? **
 * *Chromosome 11 **

= How is Usher Syndrome Inherited? = =This disease is inherited by having a copy of the gene in each cell mutations and this is known as Autosomal Recessive Pattern. Parents with the A.R.P carry one copy of the mutated gene but do not show symptoms. Therefore passed can be passed on to their offsprings.= = Populations with the disease or possibilty of having the disease: = = = =Works Cited= //Usher Syndrome & Retinitis Pigmentosa: Information & Referrals//.
