Swyer Syndrome

Swyer Syndrome:

Swyer syndrome is a rare condition which is estimated to occur in about one in 80,000 people.

• Swyer Syndrome is a rare difference of sex development, medically known as 46, XY complete gonadal dysgenesis.
• It is a rare genetic condition where individuals have one X and one Y chromosome in each cell (typically associated with males) but develop female reproductive structures.
• It is characterized by the failure of the sex glands (i.e., testicles or ovaries) to develop.
• It results from disruption of the genetic pathway involved in testicular development during early embryonic development.
• This syndrome is one of many “Disorders of Sex Development”, or DSDs.
• People with Swyer syndrome are genetically male but phenotypically female, meaning they have a female appearance and female external genitalia.
• There is currently no treatment that can change the 46, XY chromosome pattern or turn the streak gonads into functioning ovaries.
• However, the effects of Swyer syndrome can be effectively managed through hormone replacement therapy.
