Dwarfism can result from many medical conditions, each with its own separate symptoms and causes. Extreme shortness in humans with proportional body parts usually has a hormonal cause, such as growth hormone deficiency, once called pituitary dwarfism.
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 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.
Laron syndrome (LS), also known as growth hormone insensitivity or growth hormone receptor deficiency (GHRD), is an autosomal recessive disorder characterized by a lack of insulin-like growth factor 1 (IGF-1; somatomedin-C) production in response to growth hormone (GH; hGH; somatotropin). [6]
Bella was born with three rare medical conditions: dwarfism, a bowel disease called Hirschsprung disease and severe combined immunodeficiency, which effects the immune system, according to ...

“Little People, Big World” star Zach Roloff and his three children, Jackson, 6, Lilah, 4, and Josiah, 23 months, all have dwarfism. While Zach has been living with the genetic condition for 33 ...
Shortened stature can result from growth hormone deficiency, starvation, portal systemic shunts, renal disease, hypothyroidism, diabetes mellitus and other conditions. Any of these conditions can be established in a population through genetic engineering, selective breeding, or insular dwarfism, or some combination of the above.
