Musculoskeletal problems often requires surgical (orthopedic or plastic) interventions at a young age or pain and or/ anti-inflammatory medications. [orpha.net]

Pain from osteoporosis becomes more severe during adolescence. [ncbi.nlm.nih.gov]
- Short Stature
Although there is no universally accepted definition of short stature, many refer to "short stature" as height more than 2 standard deviations below the mean for age and gender (or below the 3rd percentile for age and gender dependent norms). [ncbi.nlm.nih.gov]
Stature is short and growth is much slower than normal. There is no mucopoly- sacchariduria and the serum does contain increased amounts of beta hexosaminidases. [passeidireto.com]
Other musculoskeletal problems like dysostosis multiplex, short stature, osteopenia, osteoarthritis, spinal cord compression and carpal tunnel syndrome are common in MLIII. [orpha.net]
Clinical features range from early developmental delay, coarse facial features, short stature, dysostosis multiplex, and hepatosplenomegaly to late onset cherry-red spot myoclonus syndrome. [mayomedicallaboratories.com]

Symptoms of aortic insufficiency may include palpitations, fatigue, shortness of breath, and chest pain. Causes Pseudo-Hurler polydystrophy is inherited as an autosomal recessive trait. [rarediseases.org]

Respiratoric
- Respiratory Insufficiency
Progressive mucosal thickening narrows the airways, and gradual stiffening of the thoracic cage contributes to respiratory insufficiency, the most common cause of death. [ncbi.nlm.nih.gov]
Later onset forms present with proximal muscle weakness and respiratory insufficiency. [mayomedicallaboratories.com]
Gastrointestinal
- Failure to Thrive
Children at risk for failure to thrive (growth failure) may need nutritional supplements, especially iron and vitamin B12 for persons with ML IV. [ninds.nih.gov]
It has a rapidly progressive course of failure to thrive and developmental delay, leading to death by age 5-8 years, usually from cardiorespiratory complications. Birth weight and length are below the reference range. [emedicine.medscape.com]
Musculoskeletal
- Joint Stiffness
The purpose of this article is to report three patients with ML III, presenting quite different clinical courses: Patient 1 is a 13-year-old girl in whom the only symptoms of ML III were joint stiffness of the hands. [ncbi.nlm.nih.gov]
The symptoms of this disorder are similar, but less severe than those of I-cell disease (mucolipidosis type II) and may include progressive joint stiffness, curvature of the spine (scoliosis), and/or skeletal deformities of the hands (e.g., claw-hands [informationtherapy.in]

The joint stiffness makes it difficult for pseudo-Hurler polydystrophy patients to dress themselves without assistance. [themedicalbiochemistrypage.org]
- Hip Dislocation
Skeletal abnormalities include kyphoscoliosis, anterior beaking and wedging of the vertebral bodies, a lumbar gibbus deformity, widening of the ribs, proximal pointing of the metacarpals, congenital hip dislocation, fractures, bilateral talipes equinovarus [emedicine.medscape.com]

Workup
This is the recommended test for the initial workup of a suspected oligosaccharidosis disorder. [mayomedicallaboratories.com]
Hypertrophy
- Ventricular Hypertrophy
Cardiorespiratory complications (restrictive lung disease, thickening and insufficiency of the mitral and aortic valves, left and/or right ventricular hypertrophy) are common causes of death, typically in early to middle adulthood. [ncbi.nlm.nih.gov]
Treatment
(May 2017) Treatment[edit] There is no cure for Pseudo-Hurler Polydystrophy/Mucolipidosis IIIA. Treatment is limited to controlling or reducing symptoms associated with this disorder. [en.wikipedia.org]
Management and treatment There are currently no curative or disease-modifying treatments available for MLIII. [orpha.net]
Prognosis
Prognosis Symptoms of ML can be congenital (present at birth) or begin in early childhood or adolescence. Early symptoms can include skeletal abnormalities, vision problems and developmental delays. [ninds.nih.gov]
Prognosis The MLIII α/ β subtype has a broad phenotypic range, from severely affected patients that die in childhood to milder affected patients displaying primarily skeletal symptoms, who survive into adulthood. [orpha.net]
It is difficult to predict the clinical phenotype from only enzymatic or biochemical characteristics.15 From a clinical standpoint, early prediction of prognosis is necessary. [nature.com]

Etiology
Their etiology is not precisely century with the first clinical recognition of known, so we have included chapters that dis symptoms and patterns for diagnosis of car cuss many aspects of congenital cardiac mal diovascular diseases. [books.google.com]
They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]
Etiology It is caused by mutation in a gene encoding the alpha and beta subunit precursor gene of GLcNAc-phos- photransferase. This gene is located on 12q23.2. [passeidireto.com]
The etiology of the disease remains unknown, but it is likely multifactorial. However, the genetic basis for this condition is defined by multiple genes that have only modest effect on disease susceptibility. [ped-rheum.biomedcentral.com]
Epidemiology
The discussion covers the phenotype spectrum, epidemiology, mode of inheritance, pathogenesis, and clinical profile of each condition, all of which is accompanied by a wealth of illustrations. [books.google.com]
Summary Epidemiology MLII and mucolipidosis type III (MLIII) represent a spectrum of severity. The estimated combined prevalence at birth of MLII and MLIII is estimated between 1/ 37,000-455,000 worldwide. [orpha.net]
Epidemiology In 2005, Marsden et al compiled a report of physician narratives from an epidemiologic study regarding infantile-onset Pompe disease. [emedicine.medscape.com]
Pathophysiology
[citation needed] Pathophysiology[edit] As in Mucolipidosis II, Mucolipidosis III results from genetic defects in GlcNAc phosphotransferase (N-acetylglucosamine-1-phosphotransferase). [en.wikipedia.org]
However, there is a great variability among patients - there are diagnosed individuals with ML III living in their sixties. [ citation needed ] Pathophysiology As in Mucolipidosis II, Mucolipidosis III results from genetic defects in GlcNAc phosphotransferase [wikiwand.com]

Prevention
This mutation was found in combination with severe mutations (i.e., mutations preventing the generation of active enzyme) in MLII and with mild mutations (i.e., mutations allowing the generation of active enzyme) in MLIIIA. [ncbi.nlm.nih.gov]
Succinct, targeted coverage of normal childhood growth and development, as well as the diagnosis, management, and prevention of common pediatric diseases and disorders, make this an ideal medical reference book for students, pediatric residents, nurse [books.google.com]
Prevention of secondary complications : Because of concerns about airway management, surgical intervention should be undertaken only in tertiary care settings with pediatric anesthesiologists. [ismrd.org]
Mutations in the GNPTAB gene that cause mucolipidosis II alpha/beta prevent the production of any functional GlcNAc-1-phosphotransferase. Without this enzyme, digestive enzymes cannot be tagged with M6P and transported to lysosomes. [medlineplus.gov]
This mutation was the most frequent in their study and was found in both the homozygous and compound heterozygous state, in combination with severe mutations (i.e., mutations preventing the generation of active enzyme) in ML II and with mild mutations [catalog.coriell.org]
