mucopolysaccharidosis type iva, galactosamine-6-sulfatase deficiency, mucopolysaccharidosis type ivb, beta galactosidase deficiency, morquio syndrome, inherited disease belonging, group of mucopolysaccharide storage diseases, two forms, recognized, type a, type b, type a disease is characterized by the absence, the enzyme galactosamine-6-sulfatase, excretion of keratan sulfate, in the urine, type b disease results from deficiency, the enzyme beta galactosidase, in both types there is accumulation, brain of abnormally large amounts of a substance, mucopolysaccharide, morquio syndrome is transmitted, an autosomal recessive trait, has several symptoms in common, mucopolysaccharide storage diseases coarse facial features, short stature, skeletal, joint abnormalities, sanfilippo syndrome, onset of symptoms is delayed, first year, life expectancy, exceed 20 years, unlike sanfilippo syndrome, mental development, normal, family history of morquio syndrome, coarse facial features, mild than either hunter, hurler syndrome, large head, macrocephaly, knock-knees, widely spaced teeth, bell-shaped chest, ribs flared out, bottom, short stature, a particularly short trunk, hypermobile joints, abnormal development of many bones, the spine, compression, the spinal cord, lead to weakness, paralysis, physical examination, testing shows, cloudy cornea, liver enlargement, inguinal hernias, kyphoscoliosis, abnormal curvature, the spine, short stature, short trunk, aortic regurgitation, heart murmur, loss of nerve function below the neck, x-ray, the long bones, x-ray, the ribs, x-ray, the spine shows abnormal vertebrae, osteoporosis, urine chemistry, keratosulfate, chondroitin sulfate increased, culture of skin fibroblasts, white blood cells, deficient galactosamine-6-sulfatase, beta galactosidase enzyme activity, hearing test, slit-lamp eye exam, abnormal deposits in cornea, echocardiogram, thickened heart valves, genetic testing available, no specific treatment, morquio syndrome, they occur, patients, morquio syndrome should have mri, the lower skull, upper neck, upper vertebrae, underdeveloped, a spinal fusion, prevent irreversible spinal cord injury, bone marrow transplantation, enzyme replacement therapy available, in the future, national mps society, mpssociety, bone abnormalities represent a significant problem, correction, surgery, made where possible, small vertebrae, top, the neck, cause slippage that damages the spinal cord so that paralysis, death, a result of cardiac complications, heart failure, vision, walking problems related to abnormal curvature, the spine, abnormal neck bones, cause spinal cord damage, cause severe disease, paralysis, not caught early, - spinal fusion, prevent this, breathing problems, symptoms of morquio syndrome occur, genetic counseling, prospective parents, a family history of morquio syndrome.
