1. Achondroplasia

   Achondroplasia is a genetic disorder with an autosomal dominant pattern of inheritance whose primary feature is dwarfism. In those with the condition, the arms and legs are short, while the torso is typically of normal length. Those affected have an average adult height of 131 centimetres (4 ft 4 in) for males and 123 centimetres (4 ft) for females. Other features can include an enlarged head and prominent forehead. Complications can include sleep apnea or recurrent ear infections. Achondroplasia includes short-limb skeletal dysplasia with severe combined immunodeficiency. Achondroplasia is caused by a mutation in the fibroblast growth factor receptor 3 (FGFR3) gene that results in its protein being overactive. Achondroplasia results in impaired endochondral bone growth (bone growth within cartilage). The disorder has an autosomal dominant mode of inheritance, meaning only one mutated copy of the gene is required for the condition to occur. About 80% of cases occur in children of parents of average stature and result from a new mutation, which most commonly originates as a spontaneous change during spermatogenesis. The rest are inherited from a parent with the condition. The risk of a new mutation increases with the age of the father. In families with two affected parents, children who inherit both affected genes typically die before birth or in early infancy from breathing difficulties. The condition is generally diagnosed based on the clinical features but may be confirmed by genetic testing.Treatments may include support groups and growth hormone therapy. Efforts to treat or prevent complications such as obesity, hydrocephalus, obstructive sleep apnea, middle ear infections or spinal stenosis may be required. Achondroplasia is the most common cause of dwarfism and affects about 1 in 27,500 people.

1. achondroplasia

   Achondroplasia is a genetic disorder that is characterized by abnormal bone growth leading to dwarfism. This condition affects the conversion of cartilage into bones, particularly in the long bones of the arms and legs. Individuals with achondroplasia have a normal lifespan and intelligence, but may experience health complications such as breathing and neurological issues. It is the most common type of short-limbed dwarfism.

1. Achondroplasia

   Achondroplasia is a common cause of dwarfism. It occurs as a sporadic mutation in approximately 75% of cases or may be inherited as an autosomal dominant genetic disorder. People with achondroplasia have short stature, with an average adult height of 131 centimeters for males and 123 centimeters for females. Achondroplastic adults are known to be as short as 62.8 cm [2 ft 0.7 in]. The disorder itself is caused by a change in the DNA for fibroblast growth factor receptor 3, which causes an abnormality of cartilage formation. If both parents of a child have achondroplasia, and both parents pass on the mutant gene, then it is very unlikely that the homozygous child will live past a few months of its life. The prevalence is approximately 1 in 25,000.

1. Achondroplasia

   An autosomal dominant disorder that is the most frequent form of short-limb dwarfism. Affected individuals exhibit short stature caused by rhizomelic shortening of the limbs, characteristic facies with frontal bossing and mid-face hypoplasia, exaggerated lumbar lordosis, limitation of elbow extension, genu varum, and trident hand.
