LAMA2 Retrospective Review of Medical Charts in Infants & Toddlers With LAMA2-Congenital Muscular Dystrophy
This retrospective chart review study of 75-120 LAMA2-CMD patients will expand the investigators understanding of the natural history of this disease. Current and pending publications cover research performed only in ages 5-16 years; there is currently no documented natural history for patients ages 0-5 years. Data collected in this study has the potential to inform the design of future interventional studies that draw nearer to clinical trial readiness every day.
A LAMA2-related Muscular Dystrophy Study: Brain Magnetic Resonance Imaging (MRI)and Brain Electrophysiology Evaluation
Laminin alpha-2 (LAMA2)-related muscular dystrophy (LAMA2-MD, Merosin Deficient CMD) is a form of congenital muscular dystrophy (CMD). A person with LAMA2-MD will have changes on brain imaging (MRI), a decrease or absence of the protein merosin (laminin 211) on muscle or skin biopsy and changes in the LAMA2 gene that are inherited from both parents. Several studies have described the changes on brain MRI. Brain changes on MRI do not correlate with the partial reduction or absence of merosin on muscle or skin biopsy. 8-30% of people with LAMA2-MD develop seizures. The types of seizures, electroencephalogram changes and common treatment regimens have not been characterized. This study will review the magnetic resonance imaging (MRI) changes, determine whether certain brain MRI changes are linked to seizures and define the common seizure treatment regimens.
Prospective Study of Adverse Event Rates in Males With X-Linked Myotubular Myopathy
X-Linked myotubular myopathy (XLMTM), a form of centronuclear myopathy (CNM) is the result of a mutation in the MTM1 (myotubularin) gene which leads to altered myotubularin. Myotubularin is essential for optimum muscle function. To date, over 100 mutations have been described resulting in a range of disease onset and symptom severity. The early onset form presents with neonatal hypotonia, muscle weakness, respiratory distress and an ongoing requirement for continuous ventilatory support with the inability to maintain a sitting position once placed. Males with both later onset and milder symptoms usually do not require ongoing ventilatory support, achieve a higher maximal motor function with ability to sit when placed and even walk, and have improved survival rates. Males with XLMTM may experience complications (events) at birth and throughout their lifetime. The goal of the study is to identify the number of events over twelve months in males with genetically confirmed XLMTM. Parents or affected individuals over the age of 18 years who are able to access telephone will provide answers to an established event survey to evaluate the frequency and types of events. Emergency department, hospital admissions and mortality will be confirmed by obtaining medical reports.
The investigators hypothesize that there will be no association between the frequency of events and markers of clinical severity including the need for ventilatory support at birth, current level of ventilatory support (no support, support less than 12 hours, support more than 12 hours) and current motor function (walking, sitting without support, inability to sit without support).
