Léri-Weill Dyschondrosteosis is a genetic disorder that affects bone growth. It is hereditary and follows an autosomal dominant pattern of inheritance. This means that if one parent carries the gene mutation, there is a 50% chance of passing it on to their children. However, it is important to consult with a healthcare professional or genetic counselor for a comprehensive evaluation and understanding of the specific genetic factors involved.
Léri-Weill Dyschondrosteosis (LWD) is a rare genetic disorder that affects bone growth and development. It is characterized by short stature, short forearms and lower legs, and a characteristic deformity of the wrist known as Madelung deformity.
The inheritance pattern of Léri-Weill Dyschondrosteosis is autosomal dominant, which means that an affected individual has a 50% chance of passing the condition on to each of their children. This pattern of inheritance indicates that a single copy of the mutated gene is sufficient to cause the disorder.
The specific gene associated with Léri-Weill Dyschondrosteosis is the SHOX gene, located on the X and Y chromosomes. Mutations in this gene disrupt the normal growth and development of bones, leading to the characteristic features of LWD.
It is important to note that Léri-Weill Dyschondrosteosis can also occur sporadically, meaning that it can arise in individuals with no family history of the condition. In these cases, the mutation in the SHOX gene occurs spontaneously during the formation of reproductive cells or early embryonic development.
Genetic testing can be performed to confirm a diagnosis of Léri-Weill Dyschondrosteosis and to identify the specific mutation in the SHOX gene. This information can be valuable for genetic counseling, as it allows individuals and families to understand the likelihood of passing the condition on to future generations.
