Congenital muscular dystrophy-infantile cataract-hypogonadism syndrome is a very rare genetic disorder which is characterized by congenital muscular dystrophy, infantile-onset cataract, and hypogonadism. Males usually develop Klinefelter syndrome while females develop agenesis of the ovaries. [2] It has been described in eight individuals of ...
Bethlem myopathy is a slowly progressive muscle disease characterized predominantly by contractures, rigidity of the spine, skin abnormalities and proximal muscle weakness. [5] [11] Symptoms may present as early as infancy, with typical contractures and hyperlaxity of joints; however, in some patients, symptoms may go unnoticed until ...
Myotonic dystrophy (DM) is a type of muscular dystrophy, a group of genetic disorders that cause progressive muscle loss and weakness. [1] In DM, muscles are often unable to relax after contraction. [1] Other manifestations may include cataracts, intellectual disability and heart conduction problems.
Diagnostic method. Physical exam, Medical history [ 3] Medication. Physical therapy, Surgery (scoliosis) [ 3] Ullrich congenital muscular dystrophy (UCMD) is a form of congenital muscular dystrophy. There are two forms: UCMD1 and UCMD2. [ 4] UCMD1 is associated with variants of type VI collagen, while UCMD2 is associated with variants of type ...
Muscular dystrophies ( MD) are a genetically and clinically heterogeneous group of rare neuromuscular diseases that cause progressive weakness and breakdown of skeletal muscles over time. [ 1] The disorders differ as to which muscles are primarily affected, the degree of weakness, how fast they worsen, and when symptoms begin. [ 1]
1 in 10,000 (Finland) - 1 in 100,000 (worldwide) Myotonia congenita is a congenital neuromuscular channelopathy that affects skeletal muscles (muscles used for movement). It is a genetic disorder. The hallmark of the disease is the failure of initiated contraction to terminate, often referred to as delayed relaxation of the muscles ( myotonia ...
Congenital muscular dystrophies (CMDs) are autosomal recessively inherited, except in some cases of de novo gene mutation and Ullrich congenital muscular dystrophy. [ 8][ 9] This means that in most cases, both parents must be carriers of a CMD gene in order for it to be inherited. CMDs are heterogenous and thus far there have been 35 genes ...
Duchenne muscular dystrophy ( DMD) is a severe type of muscular dystrophy predominantly affecting boys. [ 3][ 6][ 7] The onset of muscle weakness typically begins around age four, with rapid progression. [ 2] Initially, muscle loss occurs in the thighs and pelvis, extending to the arms, [ 3] which can lead to difficulties in standing up. [ 3]
