Question 1

what causes dwarfism?

Accepted Answer

Often gene mutation: According to the mayo clinic most cases of dwarfism are genetic (gene mutation) in nature however sometimes the cause is not known.

Question 2

is osteochondrodysplasia the cause of dwarfism?

Accepted Answer

Yes it could: Osteochondrodysplasias are a group of hereditary disorders in which bone or cartilage grows abnormally, so that the skeleton develops abnormally. Many types of osteochondrodysplasia cause dwarfism. Achondroplasia is the most common of the many types of short-limbed dwarfism.

Question 3

is dwarfism caused by a recessive or dominant allele?

Accepted Answer

It depends: It depends on what one means by dwarfism: a short stature in general (this depends on your ethnic origin as well) or a genetic syndrome which involves extremely short stature as part of the clinical picture. Some of them are dominant = inherited from a parent or rose spontaneously (de novo) in the individual. Some of them are recessive (=parents unaffected carriers of the condition).

Question 4

dwarfism is caused by the mutation of which chromosome?

Accepted Answer

Many types: There are many different types, for example, the most common type is achondroplasia which is on the short arm of chromosome 4.

Question 5

what is the gene or chromosome that causes dwarfism?

Accepted Answer

Genes on chromosomes: the knowledge of the osteochondrodystrophies causing dwarfism has in some cases reached the molecular level. There are dozens of different kinds.  Some are much better elucidated than others.  In some, therapy has become available.

Question 6

help docs! i'm trying to find out what causes pituitary dwarfism (hypo-somatotropism) ?

Accepted Answer

Multiple causes: Hyposomatotropism has a variety of causes including genetic controls over production ; secretion of pituitary hormones. This cause is often detected at birth due to other accompanying signs of physical abnormalities which occur in utero. If not genetic then, other causes include trauma, infections, sarcoidosis, tumors, pituitary gland developmental problems, and cranial irradiation. Best to you!

Question 7

what chromosome carries the gene that can cause dwarfism?

Accepted Answer

Probably all of them: There are a few hundred different genetic loci that produce dwarfism. Achondroplastic dwarfism is usually the result of a mutation on chromosome 4.

Question 8

could pediatric neuro-sarcoidosis cause pituitary dwarfism (hyposomatotropism) in children ?

Accepted Answer

It could be a cause: Causes of hypopituitarism can directly affect the pituitary gland or indirectly through the hypothalamus, which in turn affects the pituitary gland. Causes of hypopituitarism, of which there are many, includes sarcoidosis - a rare inflammation of the lymph nodes and other tissues throughout the body.

Question 9

what are the symptoms of dwarfism?

Accepted Answer

Little people: Adult under 4 feet 10 inches and they are classified according to cause and proportionality of body parts.

Question 10

what is done to diagnose dwarfism?

Accepted Answer

Prenatal ultrasound.: Screening with prenatal ultrasound is one way to screen for certain types of dwarfism that could potentially be lethal. Prenatal screening and diagnosis are primarily performed in the second trimester, but late first trimester fetal structural assessment is becoming more common with advances in transvaginal ultrasound imaging and the widespread use of first trimester screening for down syndrome.
