Summaries for Masa Syndrome

OMIM : 57 The hereditary spastic paraplegias (SPG) are a group of clinically and genetically diverse disorders characterized by progressive, usually severe, lower extremity spasticity; see reviews of Fink et al. (1996) and Fink (1997). Some forms of SPG are considered 'uncomplicated,' i.e., progressive spasticity occurs in isolation; others are considered 'complicated,' i.e., progressive spasticity occurs with other neurologic features. X-linked, autosomal dominant (see 182600), and autosomal recessive (see 270800) forms of SPG have been described. Spastic paraplegia-1 is usually called MASA syndrome, the designation originally suggested by Bianchine and Lewis (1974), because the main clinical features are summarized by the acronym MASA (mental retardation, aphasia, shuffling gait, and adducted thumbs). The shuffling gait is probably caused by spasticity of the lower limbs, and all affected males have been reported to have increased reflexes. The adducted thumbs are thought to be caused by hypoplastic or absent extensor pollicis longus or brevis muscles. In affected males, the onset of speech is delayed (Winter et al., 1989). See 314100 for isolated X-linked congenital clasped thumb and 201550 for an autosomal adducted thumbs syndrome. (303350)

MalaCards based summary : Masa Syndrome, also known as l1 syndrome, is related to paraplegia and spastic paraplegia 1, and has symptoms including muscle spasticity An important gene associated with Masa Syndrome is L1CAM (L1 Cell Adhesion Molecule), and among its related pathways/superpathways are Axon guidance and Cell adhesion molecules (CAMs). Affiliated tissues include testes, skeletal muscle and brain, and related phenotypes are delayed speech and language development and intellectual disability

UniProtKB/Swiss-Prot : 75 Mental retardation, aphasia, shuffling gait, and adducted thumbs syndrome: An X-linked recessive syndrome with a highly variable clinical spectrum. Main clinical features include spasticity and hyperreflexia of lower limbs, shuffling gait, mental retardation, aphasia and adducted thumbs. The features of spasticity have been referred to as complicated spastic paraplegia type 1 (SPG1). Some patients manifest corpus callosum hypoplasia and hydrocephalus. Inter- and intrafamilial variability is very wide, such that patients with hydrocephalus, MASA, SPG1, and agenesis of corpus callosum can be present within the same family. Spastic paraplegia 1, X-linked: A form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body.

NIH Rare Diseases : 53 L1 syndrome is a mild to severe congenital disorder with hydrocephalus of varying degrees of severity, intellectual disability, spasticity of the legs, and adducted thumbs. It includes several conditions, some more severe than others: X-linked hydrocephalus with stenosis of the aqueduct of Sylvius (HSAS) - the most severe of all; MASA syndrome (intellectual disability, aphasia (delayed speech), spastic paraplegia (shuffling gait), adducted thumbs); SPG1 (X-linked complicated hereditary spastic paraplegia type 1) X-linked complicated corpus callosum agenesis. It is inherited in an X-linked manner; therefore, it only affects males. It is caused by alterations (mutations) in L1CAM gene. The diagnosis is made in males who have the clinical and neurologic findings and a family history consistent with X-linked inheritance and is confirmed by a genetic test showing the L1CAM gene mutation. The treatment involves doing a surgery for the hydrocephalus.

Genetics Home Reference : 25 L1 syndrome describes a group of conditions that primarily affect the nervous system and occur almost exclusively in males. These conditions vary in severity and include, from most severe to least, X-linked hydrocephalus with stenosis of the aqueduct of Sylvius (HSAS), MASA syndrome, spastic paraplegia type 1, and X-linked complicated corpus callosum agenesis.

Disease Ontology : 12 A hereditary spastic paraplegia that is characterized by hydrocephalus, spasticity of the lower limbs, adducted thumbs, aphasia, seizures, agenesis of the corpus callosum and intellectual disability in the mild to moderate range.
