46,XX/46,XY

From WikiMD's Wellnesspedia

46,XX/46,XY is a rare chromosomal disorder where individuals have both XX and XY chromosomes in different cells. This condition is also known as chimerism or mosaicism. It is a form of Disorder of Sex Development (DSD), which refers to any congenital condition in which development of chromosomal, gonadal, or anatomical sex is atypical.

Causes[edit | edit source]

The cause of 46,XX/46,XY chimerism is not fully understood. It is believed to occur due to the fusion of two fertilized eggs, or zygotes, early in embryonic development. This results in an individual with cells that have different sets of chromosomes.

Symptoms[edit | edit source]

The symptoms of 46,XX/46,XY chimerism can vary greatly. Some individuals may have ambiguous genitalia, while others may appear typically male or female. Other possible symptoms include infertility, delayed puberty, and differences in secondary sexual characteristics.

Diagnosis[edit | edit source]

Diagnosis of 46,XX/46,XY chimerism is often made through genetic testing, which can identify the presence of both XX and XY cells. This can be done through a blood test, skin biopsy, or other types of tissue sampling.

Treatment[edit | edit source]

Treatment for 46,XX/46,XY chimerism is individualized and depends on the specific symptoms and needs of the individual. This may include hormone therapy, surgery to correct ambiguous genitalia, and counseling or mental health support.
