Treatment There are many treatments your baby’s health care provider may recommend to address the signs of mucopolysaccharidosis type I (MPS I) and help your baby live a healthier life. [babysfirsttest.org]

Management and treatment General anaesthesia may be problematic in patients with MPS type IV, due to intubation difficulties. [orpha.net]

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]

In the presence of early corneal opacities, the ophthalmologist has to consider a metabolic disease, and an early diagnosis improves the ocular and systemic prognosis. [ijponline.biomedcentral.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]

Summary Epidemiology Prevalence is approximately 1/250 000 for type IVA but incidence varies widely between countries. MPS IVB is even rarer. [orpha.net]

A retrospective epidemiological survey covering the period between 1970 and 2010 was implemented. Multiple ascertainment sources were used to identify affected patients. [link.springer.com]

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]
