Swyer syndrome is a condition in which individuals with one X chromosome and one Y chromosome in each cell, the pattern normally found in males, have a female appearance. Those with Swyer syndrome are typically raised as females and have a female gender identity. People with this condition have female external genitalia and a normal uterus and Fallopian tubes. However, they do not have functional gonads (ovaries or testes). Instead, they have undeveloped clumps of tissue, called streak gonads. These abnormal gonads often become cancerous, so they are usually surgically removed early in life. The genes known to cause this condition include the DHH, NR0B1, NR5A1, and SRY genes. Swyer syndrome has different patterns of inheritance depending on the underlying cause.
