3. Description Of SRY Who is affected?
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. People with this disorder have female external genitalia and a normal uterus and Fallopian tubes.
Outlook or quality of life
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 removed surgically early in life.
