• 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]

• 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]

• 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]

• 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]

(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 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]

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]

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]

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]
