  1. Laron syndrome is a rare form of short stature that results from the body's inability to use growth hormone, a substance produced by the brain's pituitary gland that helps promote growth. Affected individuals are close to normal size at birth, but they experience slow growth from early childhood that results in very short stature
  2. Laron syndrome is a condition that occurs when the body is unable to utilize growth hormone. It is primarily characterized by short stature. Other signs and symptoms vary but may include reduced muscle strength and endurance; hypoglycemia in infancy; delayed puberty; short limbs (arms and legs); and obesity
  3. A Laron-szindróma. A Laron-szindrómának nevezett betegségben ugyanis a növekedési hormon a szokott módon termelődik, de a receptorok nem képesek reagálni rá, vagyis egy ún. növekedési hormon rezisztencia áll fenn. A betegség hátterében állhatnak genetikus okok, de számos egyéb kórképhez vagy állapothoz is társulhat.

GH levels are normal or increased. The disorder is caused by dysfunction of the growth hormone receptor Laron syndrome (LS) is an autosomal recessive disorder of GH resistance caused by a mutation, deletion, or insertion in the gene encoding the GH receptor (GHR, chromosome 5p13-p12). An LS-like phenotype is caused by a postreceptor defect (in the GH signaling cascade) due to a mutation in the STAT5B gene (chromosome 17q21.2), the acid-labile subunit (ALS), the IGF-1 gene, and the IGF-1 receptor Laron Syndrome / diagnosis* Laron Syndrome / genetics Male Substances Insulin-Like Growth Factor I Growth Hormone.
