achondroplastic

Achondroplastic refers to a condition characterized by achondroplasia, the most common form of dwarfism. Achondroplasia is a genetic disorder that affects bone growth, particularly in the long bones of the arms and legs. It is caused by a mutation in the FGFR3 gene, which plays a crucial role in bone development. This mutation leads to disproportionately short limbs compared to the trunk, a larger head with a prominent forehead, and a flattened bridge of the nose. Individuals with achondroplasia typically have average-sized torsos and heads, but their arms and legs are significantly shorter.

The condition is usually inherited in an autosomal dominant pattern, meaning only one copy of the mutated gene is needed to cause the disorder. In most cases, it arises from a new mutation in a parent who does not have achondroplasia. While achondroplasia primarily affects bone growth, individuals with the condition generally have normal intelligence and life expectancy. However, they may be prone to certain health issues, including respiratory problems, ear infections, and joint problems. Medical management often focuses on addressing these potential complications and providing support for growth and development. The term "achondroplastic" is used to describe individuals or conditions related to this specific type of dwarfism.
