Background:

- Some nerve and muscle disorders that start early in life (before age 25), like some forms of muscular dystrophy, can run in families. However, the genetic causes of these disorders are not known. Also, doctors do not fully understand how symptoms of these disorders change over time. Researchers want to learn more about genetic nerve and muscle disorders that start in childhood by studying affected people and their family members, as well as healthy volunteers.

Objectives:

- To better understand nerve and muscle disorders that start early in life and run in families.

Eligibility:

- Individuals at least 4 weeks old with childhood-onset muscular and nerve disorders, including those who have a later onset of a disorder that typically has childhood onset.

- Affected and unaffected family members of the individuals with muscular and nerve disorders.

- Healthy volunteers at least 4 weeks old with no nerve or muscle disorders.

Design:

- Participants will be screened with a physical exam and medical history. Genetic information will be collected from blood, saliva, cheek swab, or skin samples. Urine samples may also be collected.

- Healthy volunteers and unaffected family members will have imaging studies of the muscles. These studies will include magnetic resonance imaging (MRI) and ultrasound scans. Results will be compared with those from the affected participants.

- All participants with nerve and muscle disorders will have multiple tests, including the following:

- Imaging studies of the muscles, including ultrasound and MRI scans.

- Imaging studies of the bones, such as x-rays and DEXA scans.

- Heart and lung function tests.

- Eye exams.

- Nerve and muscle electrical activity tests and biopsies.

- Video and photo image collection of affected muscles.

- Speech, language, and swallowing evaluation.

- Lumbar puncture to collect spinal fluid for study.

- Tests of movement, attention, thinking, and coordination.

- Participants with nerve and muscle disorders will return to the Clinical Center every year. They will repeat the tests and studies at these visits.

Eligibility

INCLUSION AND EXCLUSION CRITERIA:

Probands inclusion criteria Phase 1:

1. Aged 4 weeks and older

2. Documentation of a personal history of a childhood-onset, hereditary/familial, neurological disorder or later onset of a disease that more commonly has childhood onset. Acceptable documentation includes evaluation through any or all of the following evaluations done prior to enrollment.

a. Medical history, including family history information

b. Physical examination

c. Muscle, nerve, or skin biopsy

d. Magnetic resonance imaging (MRI)

e. Electromyography (EMG)

f. Nerve conduction study (NCS)

g.Electroencephalogram (EEG)

h. Muscle ultrasound

i. Genetic, metabolic, or other laboratory testing such as increased serum Creatine Kinase (CK) and abnormal serum lactate/pyruvate ratio.

Probands inclusion criteria Phase 2:

1. Aged 4 weeks and older

2. Documentation of a defined childhood onset neuromuscular and neurogenetic disorders through phase 1 testing.

Exclusion criteria for probands Phase 1:

1.Individuals who are unable or unwilling to be examined.

2. Minors who do not have a parent or guardian able to provide informed consent.

3. Adults seen offsite who are unable to provide their own consent.

Exclusion criteria for probands Phase 2:

1. Individuals who are unable or unwilling to be examined.

2. Adults who are unable to provide their own consent and who have not previously appointed an individual with Durable Power of Attorney (DPA) or who are unable to appoint a DPA or guardian.

3. Minors who do not have a parent or guardian able to provide informed consent.

4. Adults seen offsite who are unable to provide their own consent.

Unaffected Family members - Inclusion Criteria:

1. Unaffected family members must be related by blood to a proband enrolled in the study. Biological relations may include first (parent or sibling), second (grandparents, aunts, uncles, half siblings) and third degree relatives (cousins).

2. Age 4 weeks and older.

Unaffected Family members - Exclusion Criteria:

1. Individuals whom are unable or unwilling to be examined.

2. Family members who are showing symptoms of the familial neurogenetic or neuromuscular condition (these may be enrolled as probands).

3. Neonates.

4. Adults who are unable to provide their own consent.

Healthy Volunteers - Inclusion Criteria:

1. Must be unaffected by a neurological condition.

2. Willing and able to comply with all protocol requirements and procedures, including MRI without sedation and without contrast.

3. Able to give informed assent and parent(s)/legal guardian to give informed consent in writing signed by the subject and/or parent(s)/legal guardian.

Healthy Volunteers - Exclusion Criteria:

1. Healthy volunteers who have metal objects in their body that are not MRI-safe. These include the following objects: 1) pacemakers or other implanted electrical devices; 2) brain stimulators; 3) some types of dental implants; 4) aneurysm clips (metal clips on the wall of a large artery); 5) metallic prostheses (including metal pins and rods, heart valves, and cochlear implants; 6) implanted delivery pump; 7) permanent eye liner; or 8) shrapnel fragments.

2. Healthy volunteers who have a fear of closed spaces.

3. Neonates.
