This disorder has not yet been found to be associated with any other neurologic disease or cognitive disability, and currently, no cures nor means to improve signs or symptoms have been found. [2] [5] The congenital mirror movements begin in infancy and persist throughout the patient's life, often with very little improvement, or deterioration. [3]
Congenital myopathy is a very broad term for any muscle disorder present at birth. This defect primarily affects skeletal muscle fibres and causes muscular weakness and/or hypotonia. Congenital myopathies account for one of the top neuromuscular disorders in the world today, comprising approximately 6 in 100,000 live births every year. [1]
Congenital muscular dystrophies are autosomal recessively-inherited muscle diseases. They are a group of heterogeneous disorders characterized by muscle weakness which is present at birth and the different changes on muscle biopsy that ranges from myopathic to overtly dystrophic due to the age at which the biopsy takes place. [1] [4]
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 and rigidity. [1]
Movement disorders are clinical syndromes with either an excess of movement or a paucity of voluntary and involuntary movements, unrelated to weakness or spasticity. [1] Movement disorders present with extrapyramidal symptoms and are caused by basal ganglia disease . [ 2 ]
Mutations on this gene are responsible for congenital muscular dystrophy (CMD), overlapping syndromes related to mutation have also been reported. It is located on the long arm of the chromosome 1 (1q21-q22) and encodes the proteins lamin A and lamin C. [ 1 ] These are structural proteins of intermediate filaments that provide stability and ...
Facial and extraocular muscles are affected most often; in rare cases, a person's hands might perform mirror movements. Synkinesis is usually caused by dysfunction of a particular nerve. Potential causes include improper healing after nerve trauma or neurodegeneration, as occurs in Parkinson's disease. In congenital cases, mutations of genes ...
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]
