Achondroplasia is a genetic disorder with an autosomal dominant pattern of inheritance whose primary feature is dwarfism. [3] It is the most common cause of dwarfism [4] and affects about 1 in 27,500 people. [3]
Achondroplasia in children is the most common form of dwarfism; it accounts for about 70% of all cases of dwarfism. [1] Achondroplasia falls into the category of “disproportionate dwarfism”. It is linked to a mutation in the fibroblast growth factor receptor-3. More than 250,000 people in the world are diagnosed with achondroplasia.
Achondroplasia occurs in one per 26,000 to 40,000 births, according to the nonprofit Little People of America. Most little people have a normal life expectancy, but many suffer from orthopedic ...

Dwarfism is a condition of people and animals marked by unusually small size or short stature. [1] In humans, it is sometimes defined as an adult height of less than 147 centimetres (4 ft 10 in), regardless of sex; the average adult height among people with dwarfism is 120 centimetres (4 ft).
In 1953, Krooth used the term "paternal age effect" in the context of achondroplasia, but mistakenly thought the condition represented a maternal age effect. [60] [61]: 375 The paternal age effect for achondroplasia was described by Lionel Penrose in 1955. At a DNA level, the paternal age effect was first reported in 1998 in routine paternity ...
Over 100 specific skeletal dysplasias have been identified. Chondrodystrophy is found in all races and in both females and male and occurs in around one of every 25,000 children. Chondrodystrophy and achondroplasia are the most common forms of genetic hyaline disorders. [citation needed] Hyaline cartilage caps the long bones and the spinal ...
Life expectancy in the U.S. is projected to increase from 78.3 years in 2022 to 79.9 years in 2035 and to 80.4 years in 2050 for all sexes combined, researchers said.
