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.
What is the treatment for Laron syndrome?
The only treatment option in Laron syndrome is recombinant human IGF1 administered subcutaneously at a dose of 80–120 μg/kg twice daily . Recombinant IGF-1 was shown to accelerate the linear growth rate to 8–9 cm in the first year of treatment, compared with 10–12 cm/year during GH treatment of GH-deficiency.
What is Levi Lorain dwarfism?
The Lorain-Levi syndrome is a rare form of dwarfism caused by the absence of a functional anterior pituitary gland; may be present at birth or develop during early childhood. The Levi-Lorain dwarfs lack the ability to produce somatomedin C in response to growth hormone.
What is Lebron syndrome?
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) production in response to growth hormone (GH; hGH; somatotropin).
What is the smallest type of dwarfism?
Primordial dwarfism (PD) is a form of dwarfism that results in a smaller body size in all stages of life beginning from before birth.
What is the difference between dwarfism and short stature?
 According to Ranke (1996), “Short stature is defined as a condition in which the height of an individual is two standard deviations (SD) below the corresponding mean height of a given age, sex and population group.” In medical terminology, it is known as “dwarfism.” There are two short stature types, proportionate …

Can a child have achondroplasia and dwarfism at the same time?
That means a child needs only one copy of the mutated gene to have that form of skeletal dysplasia. There is a 25% chance that a child born to a couple in which both members have achondroplasia will be of normal height. But there is also a 25% chance the child will inherit both dwarfism genes, a condition known as double-dominant syndrome.
