Eligibility
Key inclusion criteria
DMD Subject Inclusion Criteria

- Affected subjects must be male and between the ages of 2 and 30

- Affected subjects between the ages of 2 and 4 must have a diagnosis of DMD confirmed
by at least one the following OR have an older male sibling that meet at least one of
the following criteria:

- Dystrophin immunofluorescence and/or immunoblot showing complete dystrophin
deficiency, and clinical picture consistent with typical Duchenne dystrophy OR

- Gene deletion test positive (missing one or more exons) in the central rod domain
exons 25-60) of dystrophin, where reading frame can be predicted as
'out-of-frame',and clinical picture consistent with typical Duchenne dystrophy.

- Complete dystrophin gene sequencing showing an alteration (point mutation,
duplication, other) that is expected to preclude production of the dystrophin
protein(i.e. nonsense mutation, deletion/duplication leading to a downstream stop
codon),with a typical clinical picture of DMD.

- Affected subjects between the ages of 5 and 30 must either fulfill the above criteria
OR show evidence of a dystrophinopathy and clinical picture consistent with Duchenne
Muscular Dystrophy

- Participants who have documented clinical symptoms referable to a
dystrophinopathy and direct support of the diagnosis by either (1) a positive DNA
analysis for dystrophin mutation, (2) a muscle biopsy demonstrating abnormal
dystrophin, or (3) an elevated CK (>5X normal), and X-linked pedigree and an
affected family member who meets either criterion (1) or (2) as described above.

NOTE: Determination of the appropriate clinical symptoms consistent with DMD will generally
be the responsibility of the clinician. At a minimum this will include progressive loss of
function, with additional consideration for other clinical features such as a
characteristic gait, a positive Gower sign and calf pseudohypertrophy. When immunostaining
of muscle biopsy is used to determining case definition, the clinical reviewer (site PI)
should confirm that appropriate testing has ruled out a secondary deficiency of dystrophin.
Affected subjects that do not exhibit the above symptoms consistent with DMD should be
excluded.

o Muscle weakness prevalent by 5 years of age

- Non-affected adult subjects must be Parent(s) or legal guardian(s) of an eligible
affected subject.

DMD Serum Biomarker Inclusion Criteria

- Participants must meet eligibility criteria for the DMD phenotyping portion of this
study

- For the GC-treatment response cohort, participants must initiate GC treatment within
the first year of study participation (i.e. between their first study visit and their
one year follow-up visit)

Summary
Brief summary
The purpose of this study is to establish the largest long-term assessment of people with
Duchenne muscular dystrophy (DMD). In this study, the investigators associated with the
Cooperative International Neuromuscular Research Group CINRG) will take a detailed look (for
a minimum of eight years) at DMD participant's physical abilities, the medical problems they
experience, and how they use health care services. Physical abilities will be compared to a
group of healthy controls.

The second purpose of this study is to find out whether small, normal differences in the
genetic makeup of people with DMD (called "single nucleotide polymorphisms" or "SNPs") affect
how their disease progresses and relates to muscle strength/size and steroid response.

The third purpose of this study is to study genetic variations associated with DMD.

The final purpose of this study is to determine whether certain biomarkers are present in
people with DMD and not in healthy controls.
