At least three clinical types have been suggested in untreated individuals: mild (clinically recognized after age ten years, with myopathy, slow progression, and absence of skeletal abnormalities); moderate (clinically recognized before age ten years, with myopathy, slow progression, and presence of skeletal abnormalities); and severe (obvious progression leading to early death from primary central nervous system involvement or infection). Core features of untreated individuals generally include early childhood-onset non-progressive hearing loss, frequent infections due to immunodeficiency, rheumatologic symptoms (especially systemic lupus erythematosus), developmental delay / intellectual disability, low tone, ataxia, spastic paraplegia, psychiatric findings, bone disease (ranging from asymptomatic osteopenia to focal lytic or sclerotic lesions and osteonecrosis), gastrointestinal dysfunction (including diarrhea, swallowing issues / aspiration, and enlarged liver and spleen), poor growth, eye issues (including tapetoretinal degeneration and optic nerve atrophy), cardiac complications in adults, and pulmonary issues (including parenchymal lung disease). However, with the advent of enzyme replacement therapy, the natural history of this condition may change. Long-term velmanase alfa (VA) treatment outcomes are still being elucidated, but may include improvement in hearing, immunologic profile, and quality of life (improved clinical outcomes for muscle strength). Similarly, affected individuals who underwent hematopoietic stem cell transplantation (HSCT) experienced improvement in development (with preservation of previously learned skills), ability to participate in activities of daily living, stabilization or improvement in skeletal abnormalities, and improvement in hearing ability, although expressive speech and hearing deficiencies remained the most significant clinical problems after HSCT." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln"><div class="excerpt">Excerpted from the <i>GeneReview: </i><a href="/books/NBK1396" target="_blank">Alpha-Mannosidosis</a></div><div>The clinical phenotype of alpha-mannosidosis varies considerably, with a wide spectrum of clinical findings and broad variability in individual presentation. At least three clinical types have been suggested in untreated individuals: mild (clinically recognized after age ten years, with myopathy, slow progression, and absence of skeletal abnormalities); moderate (clinically recognized before age ten years, with myopathy, slow progression, and presence of skeletal abnormalities); and severe (obvious progression leading to early death from primary central nervous system involvement or infection). Core features of untreated individuals generally include early childhood-onset non-progressive hearing loss, frequent infections due to immunodeficiency, rheumatologic symptoms (especially systemic lupus erythematosus), developmental delay / intellectual disability, low tone, ataxia, spastic paraplegia, psychiatric findings, bone disease (ranging from asymptomatic osteopenia to focal lytic or sclerotic lesions and osteonecrosis), gastrointestinal dysfunction (including diarrhea, swallowing issues / aspiration, and enlarged liver and spleen), poor growth, eye issues (including tapetoretinal degeneration and optic nerve atrophy), cardiac complications in adults, and pulmonary issues (including parenchymal lung disease). However, with the advent of enzyme replacement therapy, the natural history of this condition may change. Long-term velmanase alfa (VA) treatment outcomes are still being elucidated, but may include improvement in hearing, immunologic profile, and quality of life (improved clinical outcomes for muscle strength). Similarly, affected individuals who underwent hematopoietic stem cell transplantation (HSCT) experienced improvement in development (with preservation of previously learned skills), ability to participate in activities of daily living, stabilization or improvement in skeletal abnormalities, and improvement in hearing ability, although expressive speech and hearing deficiencies remained the most significant clinical problems after HSCT. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK1396#a-mannosidosis.Summary" target="NBK1396">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK1396#a-mannosidosis.GeneReview_Scope" target="NBK1396">GeneReview Scope</a>  |  <a class="medgenPMinfo" href="/books/NBK1396#a-mannosidosis.Diagnosis" target="NBK1396">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1396#a-mannosidosis.Clinical_Characteristics" target="NBK1396">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK1396#a-mannosidosis.Genetically_Related_Allel" target="NBK1396">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK1396#a-mannosidosis.Differential_Diagnosis" target="NBK1396">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1396#a-mannosidosis.Management" target="NBK1396">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK1396#a-mannosidosis.Genetic_Counseling" target="NBK1396">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK1396#a-mannosidosis.Resources" target="NBK1396">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK1396#a-mannosidosis.Molecular_Genetics" target="NBK1396">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK1396#a-mannosidosis.Chapter_Notes" target="NBK1396">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK1396#a-mannosidosis.References" target="NBK1396">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />Alpha-mannosidosis (MANSA) is an autosomal recessive lysosomal storage disease characterized by impaired intellectual development, coarse facial features, skeletal abnormalities, hearing impairment, neurologic motor problems, and immune deficiency. Expression of the disease varies considerably, and there is a wide spectrum of clinical findings and severity. Affected children are often normal at birth and during early development. They present in early childhood with delayed psychomotor development, delayed speech, and hearing loss. Additional features include large head with prominent forehead, rounded eyebrows, flattened nasal bridge, macroglossia, widely spaced teeth, dysostosis multiplex, and motor impairment (summary by Malm and Nilssen, 2008).&#13;
Classification Systems&#13;
Two classification systems have been used to describe the clinical presentation of alpha-mannosidosis. The earlier system delineated a more severe 'type I,' which shows infantile onset, rapid mental deterioration, hypotonia, splenomegaly, severe dysostosis multiplex, and severe recurrent infections, often resulting in death by age 8 years. Individuals with the less severe 'type II' show normal early development with later childhood development of impaired intellectual development, hearing loss, coarse facies, neurologic deterioration, and survival well into adulthood (summary by Desnick et al., 1976 and Gotoda et al., 1998). A later classification system delineated 3 clinical types. Type 1 is the mildest form, with onset after age 10 years, without skeletal abnormalities and very slow progression. Type 2 is a moderate form, with onset before age 10 years, presence of skeletal abnormalities, and slow progression with development of ataxia by age 20 to 30 years. Type 3 is the severe form, with onset in early infancy, skeletal abnormalities, and obvious progression leading to early death from primary central nervous system involvement or myopathy. Most patients belong to clinical type 2 (summary by Malm and Nilssen, 2008). Despite the clinical heterogeneity of the disorder, there are no apparent genotype/phenotype correlations (Berg et al., 1999; Riise Stensland et al., 2012).  <a target="_blank" href="http://www.omim.org/entry/248500">http://www.omim.org/entry/248500</a></div><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />Alpha-mannosidosis is a rare inherited disorder that causes problems in many organs and tissues of the body. Affected individuals may have intellectual disability, distinctive facial features, and skeletal abnormalities. Characteristic facial features can include a large head, prominent forehead, low hairline, rounded eyebrows, large ears, flattened bridge of the nose, protruding jaw, widely spaced teeth, overgrown gums, and large tongue. The skeletal abnormalities that can occur in this disorder include reduced bone density (osteopenia), thickening of the bones at the top of the skull (calvaria), deformations of the bones in the spine (vertebrae), knock knees, and deterioration of the bones and joints.<br /><br />Affected individuals may also experience difficulty in coordinating movements (ataxia); muscle weakness (myopathy); delay in developing motor skills such as sitting and walking; speech impairments; increased risk of infections; enlargement of the liver and spleen (hepatosplenomegaly); a buildup of fluid in the brain (hydrocephalus); hearing loss; and a clouding of the lens of the eye (cataract). Some people with alpha-mannosidosis experience psychiatric symptoms such as depression, anxiety, or hallucinations; episodes of psychiatric disturbance may be triggered by stressors such as having undergone surgery, emotional upset, or changes in routine.<br /><br />The signs and symptoms of alpha-mannosidosis can range from mild to severe. The disorder may appear in infancy with rapid progression and severe neurological deterioration. Individuals with this early-onset form of alpha-mannosidosis often do not survive past childhood. In the most severe cases, an affected fetus may die before birth. Other individuals with alpha-mannosidosis experience milder signs and symptoms that appear later and progress more slowly. People with later-onset alpha-mannosidosis may survive into their fifties. The mildest cases may be detected only through laboratory testing and result in few if any symptoms.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/alpha-mannosidosis">https://medlineplus.gov/genetics/condition/alpha-mannosidosis</a></div></div>
