What is the prevalence of Hereditary multiple exostoses?
How many people does Hereditary multiple exostoses affect? Does it have the same prevalence in men and women? And in the different countries?
The prevalence of Hereditary multiple exostoses (HME) is estimated to be around 1 in 50,000 individuals. HME is a rare genetic disorder characterized by the development of multiple benign bone tumors called exostoses. These growths typically appear during childhood and continue to form throughout adolescence. HME can affect various bones in the body, leading to skeletal deformities, limb length discrepancies, and joint limitations. Although HME is rare, it can significantly impact an individual's quality of life and may require medical intervention or surgical management.
Hereditary multiple exostoses (HME), also known as multiple osteochondromas, is a rare genetic disorder characterized by the development of multiple benign bone tumors called osteochondromas. These tumors typically arise from the growth plates of long bones, such as the arms and legs.
The prevalence of Hereditary multiple exostoses is estimated to be around 1 in 50,000 individuals worldwide. It affects both males and females equally and can be found in various ethnic groups. However, the prevalence may vary slightly depending on the population studied.
HME is an autosomal dominant disorder, meaning that an affected individual has a 50% chance of passing the condition on to each of their children. The severity of the disease can vary widely, even within families. Some individuals may only have a few osteochondromas, while others may develop numerous tumors throughout their body.
Although osteochondromas are typically benign, they can cause various complications, including skeletal deformities, restricted joint movement, nerve compression, and an increased risk of malignant transformation. Regular monitoring and appropriate management are essential to address these potential complications and ensure the best possible outcomes for individuals with HME.
A high prevalence of this disorder has been reported in some isolated communities.
HME affects males and females in equal numbers but in general males tend to be more severely affected.
