achondroplasty
Noun: 1. A genetic disorder of bone growth: Achondroplasty is a specific inherited condition that affects the skeletal system. It occurs when cartilage, which normally forms the framework for most bones during development, is converted to bone too early or in an abnormal manner. This process, which begins before a person is born, results in a characteristic form of short-limbed dwarfism where the torso is typically of average size while the arms and legs are disproportionately short.
- Noun:
- The doctor explained that achondroplasty is the most common cause of disproportionate short stature.
- Genetic counseling can help parents understand the inheritance pattern of achondroplasty.
- Individuals with achondroplasty often have normal intelligence and life expectancy.
- Medical/Clinical Context: The term is used almost exclusively in medical, genetic, and anthropological discussions. It is a precise diagnostic term.
- The study focused on the specific FGFR3 gene mutation responsible for achondroplasty.
- Achondroplasia (n): This is the more common and technically precise spelling and term for the same condition. "Achondroplasty" is a recognized but less frequently used variant.
- Dwarfism (n): A general term for conditions resulting in short stature. Achondroplasia is a specific type of dwarfism.
- Skeletal dysplasia (n): A broader category of disorders involving abnormal bone and cartilage development, which includes achondroplasia.
- Chondrodystrophy: A somewhat older or less specific term for a disorder of cartilage development that can sometimes be used interchangeably, though achondroplasia is more precise.
The core meaning of "achondroplasty" is fixed as the specific genetic skeletal disorder described. It does not have other common meanings outside of this medical context. The key elements of its definition are: inherited, begins prenatally, involves faulty cartilage-to-bone conversion, and results in a common form of dwarfism.
-
an inherited skeletal disorder beginning before birth; cartilage is converted to bone resulting in dwarfism
