'''49,XXYYY syndrome''' is a [[intersex]] |
'''49,XXYYY syndrome''' is a [[intersex]] variation in which a [[CTM]] 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 |
Those with this variation tend to have facial dysmorphism, mild microcephaly, limitation of supination at the elbows, delayed bone age, and moderate intellectual disability (such as autism.)<ref>[https://pubmed.ncbi.nlm.nih.gov/8330452/]</ref> This variation is often considered a subset or a related variation to [[Klinefelter Syndrome|kilnefelter syndrome]]. |

Medical proffesionals 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>[https://www.karger.com/Article/PDF/129719][https://pubmed.ncbi.nlm.nih.gov/13959068/][https://op.europa.eu/en/publication-detail/-/publication/b7a528a6-2d20-4384-9e52-38579a0f3677]</ref> |
