Treatment options depend on the type of mucopolysaccharidosis present. [fulgentgenetics.com]

One change must be present in the copy of the IDUA gene that the individual inherits from their mother, and another change must be present in the copy of the IDUA gene the individual inherits from their father. [chop.edu]

The severity of the condition depends on how much IDUA activity is present. IDUA activity shows how well your baby can break down GAGs. High levels of GAGs can damage many parts of the body. [newbornscreening.hrsa.gov]

CASE REPORT The patient is a 6-year-old male who was referred to a pediatric clinic for an incidentally found CM-I and cervicothoracic syrinx [ Figure 1 ] identified during a preoperative workup prior to the surgical management of a progressive thoracolumbar [surgicalneurologyint.com]

Diagnosis See Workup. Treatment See Treatment. Pathophysiology GAGs are long, linear polysaccharide molecules composed of repeating dimers, each of which contains a hexuronic acid (or galactose in the case of keratan sulfate) and an amino sugar. [emedicine.medscape.com]

Neither treatment will completely prevent symptoms of disease, and other treatments/procedures are still commonly recommended, even for patients who have undergone transplant. [chop.edu]

What Is the Prognosis for a Person with MPS I? The prognosis for individuals with severe MPS I is generally poor. They need special education and assistance to perform ordinary daily functions and are often wheelchair-bound. [myriad.com]

Prognosis The mucopolysaccharidoses syndromes share many clinical features but have varying degrees of severity. [brainfacts.org]

Prognosis Prognosis depends on the severity of the disease and on the quality of care, which can allow patients to survive beyond the age of 50. The documents contained in this web site are presented for information purposes only. [orpha.net]

The prognosis (long-term outlook) depends upon the particular type of MPS. There are a number of different types of MPS that are designated somewhat confusingly by number (and letter), by syndrome name, and by precising what enzyme is lacking. [medicinenet.com]

The decision for surgery should be taking into account, the characterization of the metabolic disorder, its course, prognosis, and life expectancy. [neurologyindia.com]

Etiology A deficiency in one of the two enzymes required for the degradation of keratan sulfate (KS) is responsible for the MPS IV subtypes: N-acetylgalactosamine-6-sulfate sulfatase in MPS IVA, and beta-D-galactosidase in MPS IVB. [orpha.net]

An epidemiologic study of the mucopolysaccharidoses in Western Australia using multiple ascertainment sources was performed and the incidence rate for the period 1969-1996 was estimated. [emedicine.medscape.com]

The overall frequency of either p.R59H or 1622-1627insG was 57.7% of the disease-causing alleles, and this epidemiological study suggested a carrier frequency of 1:58 for this population 31. [centogene.com]
