Le Turner syndrome (dzimwe nguva zvinodaidzwa gonadal dysgenesis) Riri chirwere chemajini zvinongobata vakadzi chete. Izvo zvisina kujairika zvine chekuita neimwe yeX chromosomes (iyo machromosome ebonde). Turner syndrome inokanganisa anenge 1 pavakadzi gumi uye inowanzoonekwa makore akawanda mushure mekuberekwa, munguva yekuyaruka. Zviratidzo zvikuru kupfupika uye kusashanda zvakanaka kwemaovari. Turner syndrome inotumidzwa zita rachiremba weAmerica uyo akazviwana muna 1938, Henri Turner.

Varume vane 46 chromosomes kusanganisira maviri anonzi machromosome ebonde anonzi XY. Iyo genetic formula yemurume ndeye 46 XY. Vakadzi zvakare vane machromosomes makumi mana nematanhatu kusanganisira maviri ebonde machromosome anonzi 46 XX. Iyo genetic formula yemukadzi saka 46 XX. Muvakadzi vane Turner syndrome, musanganiswa wegeneti une X chromosome imwe chete, saka genetic formula yemukadzi ane Turner syndrome ndeye 46 X45. Pamwe vakadzi ava varikushaya X chromosome kana X chromosome iripo, asi ine abnormality inonzi kudzima. Naizvozvo pane nguva dzose kushaikwa kwechromosomal.
