XYYY Syndrome

48,XYYY syndrome is a rare intersex Y condition characterized by having three Y chromones. Symptoms can include delayed development of language and/or learning disabilities. Physical features caused by this condition 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 condition. 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. This condition is only found within AMAB individuals.

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