Hi. My name is Dongsheng
Duan, I am from the
Department of Molecular
Microbiology and Immunology
at the University of Missouri
in Columbia, Missouri.
The topic I'm going to
share with you today is
"CRISPR Editing Therapy for
Duchenne Muscular Dystrophy."
This is Part 1 of my talk.
I look forward to see you in
the second part of my talk.

Duchenne muscular dystrophy
got his name from Duchenne,
who is a French physician.
In 1868, he published
a paper describing
the key boys that have
difficulties in their
walking ability
and their movement ability.
Those kids lost their
walking ability
and became wheelchair-bound
when they became teenagers.
And because of Dr. Duchene's
seminal contribution,
so this disease got the name
of Duchenne muscular dystrophy.
On this slide, you can see
a boy who is 12 years old,
who has Duchenne
muscular dystrophy
and he cannot walk anymore.

The gene which its
mutation cause Duchenne
muscular dystrophy,
was discovered in 1987
by L. Kunkel's Group,
it turns out to be one of
the largest gene in the genome.
It has a size of 2.4 Mb with
79 exons and many isoforms.
The dystrophin protein is
about 427 Kilodaltons.
