We report the progression of polysomnographic abnormalities in a Child with mucolipidosis II, demonstrated by worsening sleep-related hypoventilation, OSA, and sleep state fragmentation despite advancing PAP therapy . Subsequent cardiac catheterization confirmed atresia of the left main coronary artery .
The patient underwent Cardiac Surgery with coronary artery bypass grafting of the left internal mammary artery to the left anterior descending coronary artery . Repeat Cardiac catheterization revealed stenosis of the right Proximal coronary artery, raising concern for progressive coronary involvement . These cargo molecules follow the secretory pathway, which is a vital part of cellular trafficking machinery in all eukaryotic Cells . It has remained unresolved, however, whether acid hydrolase binding is required for exit of the CI-MPR from the TGN . These data show that there is no block in TGN exit of the CI-MPR in the absence of Man-6-P-modified acid hydrolases .
Most cargo is sorted within, and exits from, the trans-Golgi network (TGN) . An 11-month-old Child presented with abnormal Head Shape, developmental delay and bent Bones . We report here pathological findings of an autopsy case of mucolipidosis type ii . The patient was an 8-year-old boy with mucolipidosis type ii and was complicated with hypertrophic cardiomyopathy . He suddenly developed Progressive respiratory failure and finally died .
Niemann-Pick disease-C (NPC) was confirmed by fibroblasts study using filipin stain . The second patient had a much better outcome because of prompt diagnosis and was able to undergo Bone marrow transplant as a result . This method describes the derivatization of oligosaccharides present in urine with phenyl-1-methylpyrazolone, which renders them hydrophobic, thus allowing desalting with Combi cleanup columns prior to injection . A model system, consisting of cultured skin fibroblasts from patients with mucopolysaccharidoses (MPS), showed that their defective glycosaminoglycan catabolism could be corrected by factors derived from Cells of a different genotype . For this reason we developed a mixed mode liquid chromatography tandem Mass spectrometry assay for the screening of the oligosaccharidoses which potentially mitigates many of the problems associated with thin layer chromatography .
MLII is an Autosomal recessive disease with a carrier rate estimated at 1/39 in Saguenay-Lac-Saint-Jean (SLSJ) (Quebec, Canada), which is the highest frequency documented worldwide . The Bone disease in these patients is believed to be due to hyperparathyroidism . We report a case where Bone disease was present at birth but the parathyroid hormone levels were initially normal and did not increase until 37 d of age . Supplemention with Vitamin D was needed to normalize the parathyroid hormone levels despite adequate intake of Vitamin D, calcium and phosphorus . Here, we applied the Qproteometrade mark GlycoArray kit to perform glycan analysis of heparanase, and compared the kit results with the more commonly used biochemical analyses .
Iodinated heparanase has been utilized to calculate binding affinity . Here we report on an adolescent with progressive joint contractions and other signs of mucolipidosis II who survived to the age of 14 years . The activities of serum alkaline phosphatase and parathyroid hormone were markedly elevated . We conclude that early skeletal manifestation of mucolipidosis type ii is not clearly identified and that differentiation from congenital rickets or congenital hyperparathyroidism could be difficult . These six patients exhibited a wide spectrum of clinical abnormalities, in particular shortened extremities: they included three patients with unknown causes of clinical symptoms, one patient with Sanfilippo disease, one of the seven patients with achondroplasia, and one with hypophosphotemic rickets .
The oligosaccharides were referenced against the internal standard, methyl lactose, to produce ratios for comparison with control samples . This case expands the phenotypic spectrum of mucolipidosis type ii . No useful markers were identified for krabbe disease, MPS II, Pompe disease, and Sandhoff disease .
