What is the official name of the NR5A1 gene?
The official name of this gene is “nuclear receptor subfamily 5, group A, member 1.”
NR5A1 is the gene's official symbol. The NR5A1 gene is also known by other names, listed below.
What is the normal function of the NR5A1 gene?
The NR5A1 gene provides instructions for producing a transcription factor called the steroidogenic factor 1. A transcription factor is a protein that attaches (binds) to specific regions of DNA and helps control the activity of particular genes. Steroidogenic factor 1 helps control the activity of several genes related to the development of the gonads (ovaries and testes) and the adrenal glands, which are small glands located on top of each kidney.
How are changes in the NR5A1 gene related to health conditions?
- Swyer syndrome - caused by mutations in the NR5A1 gene
NR5A1 gene mutations have been identified in a small number of people with Swyer syndrome, also known as 46, XY complete or pure gonadal dysgenesis.
People normally have 46 chromosomes in each cell. Two of the 46 chromosomes, known as X and Y, are called sex chromosomes because they help determine whether a person will develop male or female sex characteristics. Females typically have two X chromosomes (46,XX), and males ordinarily have one X chromosome and one Y chromosome (46,XY).
Mutations in the NR5A1 gene in people with Swyer syndrome impair the process of male sexual differentiation, causing affected individuals to develop a female appearance despite having the chromosome pattern typical of males.
- other disorders - caused by mutations in the NR5A1 gene
NR5A1 gene mutations have been identified in people with 46,XY disorder of sex development, also known as partial gonadal dysgenesis. Affected individuals may have external genitalia that do not look clearly male or clearly female (ambiguous genitalia) or other abnormalities of the genitals and reproductive organs. They may also have abnormalities of the adrenal glands, which produce several hormones that regulate many essential functions in the body. Adrenal gland abnormalities may cause a deficiency of these hormones, resulting in a variety of health problems.
Where is the NR5A1 gene located?
Cytogenetic Location: 9q33
Molecular Location on chromosome 9: base pairs 127,243,514 to 127,269,698
The NR5A1 gene is located on the long (q) arm of chromosome 9 at position 33.
More precisely, the NR5A1 gene is located from base pair 127,243,514 to base pair 127,269,698 on chromosome 9.
