1、Hergigantismis due to a tumor in her pituitary gland.(她的巨人症是由脑垂体肿瘤引起的。) 2、But other than rare mutations that result in dwarfism orgigantism, scientists have had little success identifying genes that govern stature.(但除了那些能导致侏儒症和巨人症的基因突变,科学家们很难确定...
X-linked acrogigantism (XLAG) is a more recently identified disorder of early-onset GH excess associated with gigantism due to microduplications of theGPR101 gene on the X chromosome. While the majority of affected individuals have pituitary adenomas, elevated circulating levels of GHRH, and the ...
I argue that selection in favor of extreme gigantism is due largely to competitive interactions and to a lesser extent to predation, and that evolving ecological inter- dependencies between primary producers and consumers created the conditions that enabled some lineages of competitively...
BACKGROUND Gigantism,characterized by excessive growth and height is due to increased secretion of growth hormone,most commonly from a pituitary adenoma.In addition to the surgical and anesthetic complexity,the extreme stature of these patients presents a unique challenge for kidney transplantation in ...
The most common cause is a noncancerous tumor of the pituitary gland. Nevertheless, it can also develop due to the following disorders: multiple endocrine neoplasia type 1; Beckwith Wiedemann syndrome; Carney complex; Weaver syndrome; McCune-Albright syndrome; ...
unusually large size from birth due to familial or genetic factors or intrauterine environment (for example, maternal prediabetic state) and not to hyperpituitarism. Farlex Partner Medical Dictionary © Farlex 2012Want to thank TFD for its existence? Tell a friend about us, add a link to thi...
Step-by-Step Solution:1. Definition of Gigantism: Gigantism is a medical condition characterized by excessive growth and height due to an overproduction of growth hormone.2. Cause of Gigantism
During the reproductive period, the secretory organ secretes a milky fluid that is thought to provide nutrients to the fry16. Due to a relatively low protein content of the secretion further functions such as pheromonal gland have been discussed. As such, agglomeration pheromones for the juveniles...
Step-by-Step Solution:1. Understanding Gigantism: Gigantism is a medical condition characterized by excessive growth and height. It is classified as a disorder.2. Hormonal Cause: The pri
In CNC, GH-excess is seen in ∼79% of patients and usually due to somatotroph cell hyperplasia [27]. Somatic alterations in PRKAR1A or PRKACB have never been found in sporadic GH-secreting pituitary adenomas. Recently, our group has identified a new syndrome, that we termed 3PAs, which...
