About this trial
The goal of this observational study is to understand how young children with LAMA2-related dystrophy move and change over time. We will also learn about how this condition impacts other body systems.
Participants will undergo:
* Neuromuscular assessments * Blood collections * Swallowing and breathing assessments * Questionnaires
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Signed informed consent by the subject, parent(s) or legally authorized representative (LAR) and/or assent by the subject (when applicable).
Subject must be aged birth to less than 5.0 years of age at time of consent.
Absence of another confirmed genetic disease.
Willingness to maintain current exercise and/or physical therapy regimen for the duration of the clinical study.
Disqualifiers
Acute medical illness or hospitalization within 30 days prior to informed consent.
Participation in a previous trial of any investigational agent for LAMA2-RD within 1 month prior to informed consent, or use of any other investigational therapy (including off-label use of Losartan) within 30 days prior to informed consent, or participation in other clinical studies, within 30 days (or 3 half-lives, whichever is longer) prior to informed consent, which in the opinion of the PI, may potentially confound results from this study.
Other significant medical condition, which in the opinion of the site Principal Investigator may confound interpretation of the clinical course of LAMA2- RD.
Trial population
Study population will be neuromuscular clinic patients of site principal investigators, as well as individuals identified by our genetic counselor.

Trial outcomes
Primary outcomes
Validate the change over 24 months using the Neuromuscular Gross Motor Outcome
The Neuromuscular GRO is a 50-item assessment that measures a child's gross motor function when lying down, sitting, crawling, walking, jumping, and climbing stairs.
Validate the change over 24 months using the Bayley Scales of Infant and Toddler Development™ 4th Ed (BayleyTM-4)
The Bayley assess four areas of development: Gross Motor, Fine Motor, Speech and Language, and Social. These results are compared to typically developing children ages 15 days to 42 months. The entire assessment takes between 1 and 3 hours, with breaks.
Validate the change over 24 months using the Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders
The CHOP-Intend includes 16-items to measure a child's ability to move their body in a lying down position, supported sitting, and assisted rolling.
Validate the change over 24 months using the Motor Function Measure Scale-Short Form
The MFM-20 contains 20 items to assess a child's motor function in sitting, lying down, standing, and completing tabletop activities.
Other outcomes
Validate CK Biomarkers
Blood will be drawn at each in-person visit to test Creatine Kinase, a muscle enzyme, and to store biomarkers for future research.
Muscle Ultrasound
Biceps or Quadriceps thickness will be measured in the middle of the muscle using standard ultrasound guidance.
