Eligibility
Key inclusion criteria
Inclusion criteria:

* Age 18 to 70 (inclusive)
* Competent to provide informed consent
* Clinical diagnosis of DM1 based on research criteria1 or positive genetic test
* Comment: The clinical research criteria require myotonia, muscle weakness in a characteristic distribution, and history of similar findings in a first degree relative. Genetic testing confirmed the diagnosis of DM1 in > 99% of individuals who satisfied these criteria.2
Minimum age
18 Years
Maximum age
70 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Exclusion criteria:

* Symptomatic renal or liver disease, uncontrolled diabetes or thyroid disorder, or active malignancy other than skin cancer.
* Current alcohol or substance abuse
* Concurrent enrollment in clinical trial for DM1, or participation in trial within 6 months of entry.
* Concurrent pregnancy or planned pregnancy during the course of the study.
* Concurrent medical condition that would, in the opinion of the investigator or clinical evaluator, compromise performance on study measures.
* Note: non-ambulatory participants are not excluded, but are limited to <15% of enrollment.

Inclusion criteria for participants in the muscle biopsy sub-study:

• Of the 95 patients undergoing the tibialis anterior muscle biopsy, at least half will have at least moderate weakness of ankle dorsiflexion, defined as MRC score = 4+. This is in order to obtain a muscle tissue sample in a person more severely affected with myotonic dystrophy. Approximately 10 patients at each site will undergo the muscle biopsy.

Exclusion criteria for 95 participants in the muscle biopsy sub-study:

* Known CTG repeat expansion size less than 100 repeats, unless there are clear cut signs of limb weakness and muscle wasting. This is in order to obtain a muscle tissue sample in a person more severely affected with myotonic dystrophy.
* Use of anticoagulant such as warfarin or a direct oral anticoagulant (e.g. dabigatran) due to the increased risk of bleeding.
* Use of aspirin or non-steroidal anti-inflammatory agents should be discontinued 3 days prior to the biopsy procedure, if possible.
* Platelet count <50,000 (if known) due to the increased risk of bleeding.
* History of a bleeding disorder due to the increased risk of bleeding.
* Advanced wasting of tibialis anterior (TA) muscle that precludes needle muscle biopsy in order to ensure that a sample taken would be of muscle and not just fat and fascia.
* Previous muscle biopsy of either TA in order to provide muscle tissue samples of non-biopsied muscles.
