NR5A1 Gene
Edit

nuclear receptor subfamily 5 group A member 1

genes

1. Introduction

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.

2. Health Conditions Related to Genetic Changes

2.1. Swyer syndrome

NR5A1 gene mutations have been identified in a small number of people with Swyer syndrome, a condition affecting sexual development also known as 46,XY complete gonadal dysgenesis or 46,XY pure gonadal dysgenesis.

People usually 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. Girls and women typically have two X chromosomes (46,XX karyotype), while boys and men usually have one X chromosome and one Y chromosome (46,XY karyotype).

Mutations in the NR5A1 gene in people with Swyer syndrome affect the process of sexual differentiation, preventing affected individuals with a 46,XY karyotype from developing male gonads (testes) and causing them to develop female reproductive structures (a uterus and fallopian tubes).

2.2. Other disorders

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.

NR5A1 gene mutations that affect gonadal development and function have also been identified in people whose gonads do not produce reproductive cells (eggs or sperm). These conditions, which are called spermatogenic failure in men and premature ovarian failure in women, result in an inability to conceive children (infertility).
