Numerous control systems are involved in the growth and differentiation of chondro-osseous tissue. Theoretically, the failure of each single step will result in a peculiar skeletal dysplasia. The resulting disorders are caused by errors in the metabolism of collagen, minerals, complex carbohydrates
Deficiency of carbohydrate sulfotransferase 3 (CHST3; also known as chondroitin-6-sulfotransferase) has been reported in a single kindred so far and in association with a phenotype of severe chondrodysplasia with progressive spinal involvement. We report eight CHST3 mutations in six unrelated
We previously reported the cloning and sequencing of a 1.5-kilobase cDNA which encoded a portion of the chondroitin sulfate domain from the chick cartilage proteoglycan core protein and the localization of a species-specific monoclonal antibody epitope. Using polymerase chain reaction amplification
BACKGROUND
Acute promyelocytic leukemia (APL) is a kind of acute myeloid leukemia, which was characterized by the presence of PML/RARα fusion gene. Mutations in CHST3 have been previously reported to be associated with a rare phenotype of skeleton dysplasia, known as Spondyloepiphyseal dysplasia.
Disorders of glycoprotein synthesis have been described only recently, and few have been studied extensively at both the clinical and biochemical level. The identification and characterization of these rare diseases are important, not only for the patients and their families, but because they offer
Mucolipidosis I is characterized by Hurler-like features and skeletal dysplasia with a cherry-red macular spot and signs of neurodegeneration involving neuronal cells and myelin. Excessive amounts of sialic acid-containing compounds were found in cultured fibroblasts, leukocytes, and urine of a
BACKGROUND
A novel immunodeficiency, frequently accompanied by high serum-IgE, and caused by mutations in the PGM3 gene was described in 2014. To date there are no unique phenotype characteristics for PGM3 deficiency. PGM3 encodes a carbohydrate-modifying enzyme, phosphoglucomutase 3. Null-mutations
Patients with different types of mucopolysaccharidoses (MPS) lack specific lysosomal enzymes, which leads to tissue accumulation and urinary excretion of glycosaminoglycans (GAGs). Since little is known about the molecular composition of the excreted GAG fragments, we used two-dimensional
Desbuquois dysplasia (DD) is characterized by antenatal and postnatal short stature, multiple dislocations, and advanced carpal ossification. Two forms have been distinguished on the basis of the presence (type 1) or the absence (type 2) of characteristic hand anomalies. We have identified mutations
Genetically different bone dysplasias may manifest themselves in similar patterns of skeletal abnormalities. It is proposed to group these similar dysplasias in 'families' for two reasons: 1 The knowledge of developmental patterns shared by different genetic disorders cautions the diagnostician and
