Achondroplasia is the most common type of short-limbed dwarfism. The condition occurs in 1 in 15,000 to 40,000 newborns. Variants (also called mutations) in the gene cause achondroplasia. The gene provides instructions for making a protein that is involved in the development and maintenance of bone and brain tissue.

1998年10月12日 · Achondroplasia is inherited in an autosomal dominant manner. Around 80% of individuals with achondroplasia have parents with average stature and have achondroplasia as the result of a de novo pathogenic variant. Such parents have a very low risk of having another child with achondroplasia.

2016年7月15日 · Achondroplasia is a disorder of bone growth. It is the most common form of disproportionate short stature. It occurs in one in every 15,000 to one in 40,000 live births. What is achondroplasia? Achondroplasia is caused by a gene alteration (mutation) in the FGFR3 gene.

2023年8月23日 · Achondroplasia is a rare genetic disorder recognized as the most common primary skeletal dysplasia in humans. This form of dysplasia accounts for greater than 90% of cases of disproportionate short stature, also known as dwarfism. The term “achondroplasia” was first used in 1878 to distinguish it from rickets, one of many other abnormal ...

Nearly all cases of achondroplasia are caused by 2 pathogenic variants, both of which are point mutations that result in a single base substitution. Approximately 98% of individuals with achondroplasia have the c.1138G>A point mutation, in which guanine is replaced by adenine, altering the normal GGG codon to AGG.

2021年12月23日 · Achondroplasia is a genetic condition that affects the body’s ability to convert cartilage into bone, resulting in short limbs. The condition is caused by changes to the FGFR3 gene, which can...

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] In those with the condition, the arms and legs are short, while the torso is typically of normal length. [3]

Achondroplasia is caused by genetic mutations, also known as pathogenic variants. Genetic mutations can be hereditary, when parents pass them down to their children, or they may occur randomly when cells are dividing.

2021年12月10日 · Achondroplasia is a bone growth disorder that results in dwarfism due to a genetic mutation in the arms and legs. Achondroplasia is the most common form of short stature (adults less than 4-ft. 10-in. in height). Almost all children with achondroplasia are able to live full and healthy lives after diagnosis. What is achondroplasia?

Achondroplasia is one of a small number of so-called RAMP disorders – recurrent, autosomal dominant, male biased, paternal age effect disorders – all of which likely arise because of their positive selective effect on spermatogonia.
