:''Not to be confused with [[XXYY Syndrome]], [[XXXYY Syndrome]], [[XYYYY Syndrome]].''
'''49, XXYYY syndrome''' is a [[intersex]] variation in which a [[CTM]] individual has two extra Y chromosomes and one extra X chromosome. It is a very rare variation amongst [[AMAB|DMAB]] individuals, and it has no estimated rarity.
Those with this variation tend to have facial dysmorphism, mild microcephaly, limitation of supination at the elbows, delayed bone age, and moderate [[Neurodivergent|intellectual disability]]<ref>
== Studies ==
Medical professionals looked into tissues sampled for chromosome studies of external [[Ambiguous Genitalia|ambiguous genitalia]] and abdominal gonads, consisting of a left [[Ovotesticular|ovotestis]] and a right primitive testis, and found that they contained cells 46,XX, 47,[[XYY Syndrome|XXY]] and 49,XXYYY sex chromosomes.<ref>
