Laing distal myopathy is a slowly progressive muscle disorder that tends to begin in childhood. Early symptoms include weakness in the feet and ankles, followed by weakness in the hands and wrists. Weakness in the feet leads to tightening of the Achilles tendon, an inability to lift the big toe, and a high-stepping walk. Weakness in the hands makes it more difficult to lift the fingers, especially the third and fourth fingers. As the muscle weakness slowly progresses over the course of many years, other muscles of the body (e.g., neck, face, legs, hips, and shoulders) weaken. Other findings include scoliosis and cardiomyopathy in up to one third of individuals. Most affected people remain mobile throughout life. Life expectancy is normal.
Laing distal myopathy is caused by mutations in the _MYH7 _gene and is inherited in an autosomal dominant fashion. Treatment may include physiotherapy to prevent tightening of the Achilles tendon and splinting of the ankle. Annual neurologic examinations, evaluations for scoliosis, and regular assessments of cardiac and respiratory functions may be necessary.

The National Institutes of Health, through the National Library of Medicine, developed ClinicalTrials.gov to provide patients, family members, and members of the public with current information on clinical research studies. While no studies involving Laing distal myopathy specifically are listed at this time, there is a trial entitled Molecular and Genetic Studies of Congenital Myopathies which may be of interest to you. Click on the title to learn more. Review its "eligibility" criteria to determine its appropriateness. You can contact Elizabeth Taylor DeChene, MS CGC by phone 617-919-2169 or e-mail firstname.lastname@example.org for further details.
You can also contact the Patient Recruitment and Public Liaison (PRPL) Office at the National Institutes of Health (NIH). We recommend calling the toll-free number listed below to speak with a specialist, who can help you search for clinical trials.

The Research Portfolio Online Reporting Tool (RePORT) provides access to reports, data, and analyses of research activities at the National Institutes of Health (NIH), including information on NIH expenditures and the results of NIH-supported research. Although these projects may not conduct studies on humans, you may want to contact the investigators to learn more. Our search of this database identified the following research study which may be of interest to you. It is looking at how myosin affects skeletal muscle.
In addition, we suggest contacting the following organizations and periodically exploring their Web sites for further information on research relevant to congential myopathies and Laing distal myopathy:
