Genetic Inheritance Patterns Retinitis pigmentosa (RP) can be autosomal recessive, autosomal dominant, or x-linked. Apparently the dominant forms are often less severe. Eric's form of RP is Usher's Syndrome, which is an autosomal recessive inheritance (i.e., you must get a copy of the defective gene from your Mom and one from your Dad). Autosomal means it is not carried on one of the chromosomes that determines sex. Usher's Type II is recessive, so for Eric this means that both his Mom and Dad are carriers of this condition. His brother, Dirk, does not have any symptoms of RP. Question below Imagine that there is a genetic therapy for RP. They stick a needle into your eye and inject the working gene, which then hopefully binds to the cells in the retina that should be making the correct pigments. Would you do it? What if it would protect your remaining eyesight, but wouldn't restore what's left?

Genetic Inheritance Patterns
Retinitis pigmentosa (RP) can be autosomal recessive, autosomal dominant, or x-linked.
Apparently the dominant forms are often less severe. Eric's form of RP is Usher's
Syndrome, which is an autosomal recessive inheritance (i.e., you must get a copy of the
defective gene from your Mom and one from your Dad). Autosomal means it is not
carried on one of the chromosomes that determines sex. Usher's Type Il is recessive, so
for Eric this means that both his Mom and Dad are carriers of this condition. His
brother, Dirk, does not have any symptoms of RP.
Question below
Imagine that there is a genetic therapy for RP. They stick a needle into your
eye and inject the working gene, which then hopefully binds to the cells in
the retina that should be making the correct pigments. Would you do it?
What if it would protect your remaining eyesight, but wouldn't restore
what's left?
