XYY Syndrome or 47,XYY or Jacob's Syndrome is an intersex trait affecting approximately 1 in 1000 AMAB individuals. It is a chromosomal condition causing one to have an extra Y chromosome (XYY), instead of the typical one (XY). Symptoms may include delayed development of language and/or motor skills, involuntary tremors or tics, and increased likelihood of seizures, asthma, and learning disabilities. Physical features caused by this condition can include, increased height, a large head, flat feet, and widely spaced eyes. Since this condition does not always cause obvious or unusual symptoms some may go most or all of their lives without knowing they are effected.[2][3]
