What is Mayberry syndrome?
Mabry syndrome is a condition characterized by intellectual disability, distinctive facial features, increased levels of an enzyme called alkaline phosphatase in the blood (hyperphosphatasia), and other signs and symptoms. People with Mabry syndrome have intellectual disability that is often moderate to severe.
What is long bone syndrome?
People with Marfan syndrome tend to have excessively long bones and are commonly thin, with long, “spider-like” fingers. They may also have other skeletal malformations that require the attention of an orthopaedic specialist.
Is Paget’s disease genetic?
The cause of Paget’s disease is unknown but involves genetic factors. Familial cases display an autosomal dominant pattern of inheritance with incomplete penetrance. Genetic heterogeneity has been demonstrated and eight potential susceptibility loci identified.
What is bone disease called?
Osteoporosis is a bone disease that occurs when the body loses too much bone, makes too little bone, or both. As a result, bones become weak and may break from a fall or, in serious cases, from sneezing or minor bumps. Osteoporosis means “porous bone.” Viewed under a microscope, healthy bone looks like a honeycomb.
Is Pagets disease fatal?

|---|---|
| Stage I | 95.8% |
| Stage II | 77.7% |

Is hyperphosphatasia an autosomal recessive trait?
Hereditary hyperphosphatasia is inherited as an autosomal recessive trait. Genetic diseases are determined by the combination of genes for a particular trait that are on the chromosomes received from both the father and the mother.
What causes hereditary hyperphosphatasia?
About two-thirds of cases of hereditary hyperphosphatasia are caused by changes or disruptions (mutations) of the TNFRSF11B gene The human skeleton is living tissue that is either growing (in childhood) or being renewed (in adulthood).
What are the symptoms of hereditary hyperphosphatasia?
The symptoms of hereditary hyperphosphatasia occur because of markedly increased bone turnover. Bone turnover is a normal process in which bone gradually breaks down (bone resorption) and then reforms. If the loss of bone is greater than the rate of new bone formation, complications occur.
What are the subdivisions of hypophosphatasia?
Subdivisions of Hypophosphatasia 1 hypophosphatasia, perinatal 2 hypophosphatasia, infantile 3 hypophosphatasia, childhood (mild versus severe) 4 hypophosphatasia, adult 5 odontohypophosphatasia 6 pseudohypophosphatasia
