XYYY Syndrome


 * Not to be confused with XYYYY Syndrome or XYY Syndrome.

48,XYYY syndrome is a rare intersex variation found within AMAB/CTM individuals. This variation is characterized by having three Y chromosomes instead of having the usual amount (XY.)

Symptoms can include delayed development of language and/or learning disabilities. Physical features caused by this variation can include increased height, irregular teeth, and acne. Radioulnar stenosis (an abnormal connection between the bones of the forearm) and clinodactyly (a bent finger or toe) have also been associated with the variation. Hypogonadism and infertility is frequently reported in adults. Children generally have typical genitalia so some may not realize they are affected until later in life.

Flag
The flag was coined by beyond-mogai-pride-flags on April 16th of 2019. The colors have no confirmed meaning, however the the X and three Ys clearly represents the variation within itself.
