Seaver Cassidy Syndrome is a syndrome that - in some cases - may be considered an intersex variation, although many would say it causes intersex traits, rather than being one in of itself.
This syndrome can effect both CTM/AMAB and CTF/AFAB individuals, however CTM individuals are the ones who develop intersex-related traits from this syndrome. 80-99% CTM individuals tend to have a missing or undescended testicle and/or an irregularly formed scrotum.
80-99% of people with this syndrome have eye folds, knock knees, wide set eyes, cheekbone underdevelopment, moles, prominent and low set ears, and a wide nasal bridge. 30-79% of people with this syndrome have a large lower jaw, voice abnormalities, neurological speech impairment, intellectual disability, outward turned elbows, joint hyperflexibility, and umbilical hernia.
It is important to note that not all the symptoms listed in this page are guaranteed to occur in someone with this syndrome, as someone may only experience one or several of these symptoms, yet still hold the syndrome.
