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]
What causes growth hormone deficiency? GHD is a relatively rare condition. Slowed growth, short stature, and low blood glucose levels in infants and toddlers are among a few signs of GH deficiency ...
The latest development in the medical treatment of acromegaly is the use of growth hormone receptor antagonists. The only available member of this family is pegvisomant (Somavert). By blocking the action of the endogenous growth hormone molecules, this compound is able to control the disease activity of acromegaly in virtually everyone with ...
Some cases are associated with a lack of other pituitary hormones, in which case it is known as combined pituitary hormone deficiency. [4] Diagnosis involves blood tests to measure growth hormone levels. [2] Treatment is by growth hormone replacement using synthetic human growth hormone. [1] The frequency of the condition is unclear. [2]
For example, a child who has a profound deficiency in growth hormone (especially if they are a cancer survivor with damage to the pituitary gland) may need to continue taking HGH as an adult, ...
Isolated growth hormone deficiency (IGHD) is a rare congenital disorder characterized by growth hormone deficiency and postnatal growth failure. [ 2 ] [ 3 ] It is divided into four subtypes that vary in terms of cause and clinical presentation.
Stratton parker syndrome is a rare disorder characterized by short stature, wormian bones (extra cranial bones), and dextrocardia (displaced heart). [1] Other symptoms include dermatoglyphics, tooth deformities or missing teeth, abnormal kidney development, shortened limbs, intellectual disability, undescended testes or cryptorchidism, and anal atresia.

Hypoprolactinemia can result from autoimmune disease, [2] hypopituitarism, [1] growth hormone deficiency, [2] hypothyroidism, [2] excessive dopamine action in the tuberoinfundibular pathway and/or the anterior pituitary, and ingestion of drugs that activate the D 2 receptor, such as direct D 2 receptor agonists like bromocriptine and pergolide, and indirect D 2 receptor activators like ...
