Chromosome 18 Ring

Chromosome 18 Ring is a condition that - in some cases - may be considered an intersex condition, although many would say it causes intersex conditions rather than being one in of itself. This condition is seemingly rare, with no known estimates. This condition can cause a missing or undescended testicle, a micropenis, and/or hypospadias in CTM/AMAB individuals. Amongst CTF/AFAB individuals with this condition tend to have labial hypoplasia (one or both labias missing.)

This condition often comes with low muscle tone, strabismus, hearing loss, undersized kidneys, foot abnormalties, scoliosis, rib-cage abnormalities, umbilical and inguinal hernias, and brain defects that often lead one to fall on the autism spectrum.

It is important to note that not all the symptoms listed in this page are guaranteed to occur in someone with this condition, as someone may only experience one or several of these symptoms, yet still hold the condition.

Causes
This condition is caused when there is a defect, loss, or deletion in the 18th chromosome, which causes the ending of other chromosomes to form a ring. This chromosomal abnormality causes the formation during the fetal stage to change, and causes development to be different than usual. This could affect all cells, however it usually only affects a small handful of them.

History
This condition was first reported in 1964.

Flag
The flag was designed by FANDOM user Poggingcameron on April 30th of 2021. The blue signifies the missing or undescended testicle, the ring represents the chromosomes ending in a ring, and the minus signifies the lack of estimated people with the condition
