Izingane zethu zonke zihlukile futhi zihlukile. Ngezinye izikhathi lokhu kuhlukile kuvela ezizalweni zazo, okungukuthi, kusukela ekuzalweni. Namuhla sizokhuluma ngesimo esibangelwa ushintsho olunjalo lwezakhi zofuzo, kodwa okungakhulunywa ngaso kakhulu emphakathini. Okusho ukuthi, amangqamuzana omfana ane-chromosome engu-Y eyengeziwe, noma ngokwezokwelapha, i-XYY syndrome. Ungesabi uma uzwa lokhu, masiqonde konke ngakho kalula.
Kungani lokhu kwenzeka? Yini ebangela i-XYY syndrome?
Kalula nje, yonke iseli emzimbeni wethu inokuthile okubizwa ngokuthi ama-chromosome . Cabanga ngawo njengezincwadi zemiyalelo ezakha imizimba yethu. Ngokuvamile, iseli ngalinye lethu linalezi zincwadi zemiyalelo, noma ama-chromosome angu-46. Siwathola ngamabhangqa angu-23. Sithola elilodwa kubhangqa ngalinye, elilodwa kumama wethu nelinye kubaba wethu.
Kula mapheya angu-23, amapheya okuqala angu-22 anquma zonke ezinye izici zomzimba wethu. Amapheya angu-23 anquma ubulili bethu. Endabeni yentombazane, la mapheya angu-XX, kanti endabeni yomfana, angu-XY.
Nansi indlela i-XYY syndrome eyenzeka ngayo. Lapho umntwana ekhulelwa, kwenzeka iphutha elincane ekwakhekeni kwesidoda sikababa, okubangela ukuthi kufakwe i-chromosome Y eyengeziwe kuleso sidoda. Lokhu kubizwa ngokuthi i-nondisjunction kwisayensi yezokwelapha. Bese kuthi, wonke amaseli emzimbeni womntwana wesilisa ozelwe yileso sidoda aqukethe inhlanganisela ye-chromosome ye-XYY esikhundleni se-XY evamile.
Into ebalulekile ukuthi lokhu akulona iphutha likamama noma likababa . Futhi, akulona icala elizuzwe njengefa. Okusho ukuthi, ubaba onesifo se-XYY ngeke adlulisele lesi simo endodaneni yakhe.
Yiziphi izici zomzimba zengane enesifo se-XYY?
Lokhu kuyinkinga yangempela kubantu abaningi. Kodwa iqiniso liwukuthi, akubona bonke abafana abane-XYY syndrome ababonisa umehluko omkhulu ngokomzimba. Ngezinye izikhathi, azikho izici ezikhethekile ezibonakala ngisho nakancane.
Uhlobo lwethu lwezakhi zofuzo luyiqoqo lemiyalelo eyakha imizimba yethu. Lokhu kwakheka kwezakhi zofuzo, kanye nendawo esihlala kuyo, kunquma izici zethu zangaphandle (i-phenotype) njengokuphakama, isisindo, kanye nokubukeka.
Nokho, kunezimpawu ezithile zomzimba ezingase zihlotshaniswe nalesi simo ngezinye izikhathi. Kodwa khumbula, akuzona zonke lezi zimpawu ezisebenza kuwo wonke umuntu.
| Isici somzimba | Incazelo elula |
|---|---|
| Ukuba mude kunokwejwayelekile | Lesi yisici esivame kakhulu. Bangase babe bade kunabo bonke abanye emndenini. |
| Ikhanda elikhulu namazinyo | Ikhanda namazinyo kungaba makhulu kakhulu uma kuqhathaniswa nobukhulu bomzimba. |
| Izinyawo ezisicaba | Ukungabikho kwejika elijwayelekile emhlane ongezansi. |
| Ibanga elikhulu phakathi kwamehlo | Ibanga eliphakathi kwamehlo likhulu kancane kunelijwayelekile. |
| I-Scoliosis | Kukhona ithuba lokugoba komgogodla ohlangothini. |
| Ukwandiswa kwamasende | Amanye amasende ezingane angaba makhulu kunokujwayelekile. |
Njengoba kushiwo ngaphambili, ukuba mude kunokwejwayelekile kuyisici esivame kakhulu kulaba bantu. Ucwaningo luthole ukuthi laba bantu banekhophi eyengeziwe yesakhi sofuzo se-SHOX kuma-chromosome ethu ocansi, okubangela ukukhula kwamathambo okusheshayo, ikakhulukazi ezithweni.
Iningi lamadoda ane-XYY syndrome anokukhula okuvamile kocansi kanye namazinga e -testosterone , ngakho-ke ayakwazi ukuba ngubaba wezingane. Kodwa-ke, inani elincane kakhulu lamadoda lingase libe nezinkinga zokuzala.
Yiziphi izimpawu ezihambisana nalesi simo?
I-XYY syndrome ingahlotshaniswa nezimo ezithile zempilo kanye nobunzima bokufunda. Kodwa-ke, uhlobo lwalezi zimpawu luyahlukahluka kakhulu kumuntu nomuntu. Nakuba abanye bengase bazizwe kancane kakhulu, abanye bangase bathinteke kakhulu.
| Isigaba sezimpawu | Izimo ezingenzeka |
|---|---|
| Ukulibaziseka Kokuthuthukiswa | |
| Amakhono okunyakaza | Ukubambezeleka okuncane ezintweni ezifana nokuhlala, ukuhamba, njll. Imisipha ephansi. |
| Ukulibaziseka kwenkulumo | Ukuphuza ukuqala ukukhuluma noma ukukhubazeka kokukhuluma. |
| Izinkinga zokufunda nokuziphatha | |
| Ubunzima bokufunda | Ukuthola ubunzima bokufunda nokubhala. |
| Amaphethini okuziphatha | I-ADHD (Isifo Sokuntuleka Kokunaka Okukhulu), Isifo Sokuphazamiseka Kwe-Autism Esincane, Ukukhathazeka, Ukungaphumuli. |
| Ezinye izinkinga zempilo | |
| Izimo zomzimba | Isifuba somoya, ukuxhuzula, ukuthuthumela kwezandla. |
Nakhu okumele sonke sikukhumbule: Ukukhubazeka kwengqondo .Ukukhubazeka kwengqondo akuyona into evamile ye-XYY syndrome. Izinga lobuhlakani lalezi zingane livame ukuba ngaphakathi kwesilinganiso esijwayelekile.
I-XYY syndrome itholakala kanjani?
Lesi simo singatholakala ngokuhlolwa okwenziwa ngaphambi kokuba ingane izalwe, okungukuthi, ngesikhathi sokukhulelwa , kanye nangokuhlolwa okwenziwa kunoma yimuphi ubudala ngemva kokuzalwa.
- Ngesikhathi sokukhulelwa: Lesi simo singatholakala ngokuhlolwa okukhethekile kwezakhi zofuzo njenge- Amniocentesis noma i-Chorionic Villus Sampling okwenziwa kumama okhulelwe.
- Ngemva kokuzalwa: Ukuhlolwa kwe-karyotype kuvame ukwenziwa. Lokhu ukuhlolwa kwegazi okulula. Kunganquma ngokunembile inani lama-chromosome emaseli ethu kanye nokuhleleka kwawo.
Uma lesi simo sesitholakele, uma ingane yakho inesikhathi sokukhuluma noma ukubambezeleka kwamakhono okunyakaza, izindlela zokwelapha ezikhethekile kanye nokusekelwa kwezemfundo kungasiza. Khuluma nodokotela wakho ngalokhu futhi, uma kudingeka, mthumele kudokotela wezingane, isazi sezakhi zofuzo, noma uchwepheshe wentuthuko.
Eqinisweni, iphesenti elikhulu lamadoda anesifo se-XYY emhlabeni aphila impilo yawo yonke engazi. Lokhu kungenxa yokuthi awanazo izimpawu ezibonakalayo.
Umlayezo Wokuya Nawe Ekhaya
- I-XYY syndrome yisimo sofuzo esenzeka ngokungahleliwe. Asibangelwa yiphutha lomzali noma asizuzwe njengefa kusukela esizukulwaneni kuya kwesinye.
- Iningi labafana nabantu abadala liphila impilo enempilo, evamile ngaphandle kwezimpawu noma izimpawu ezincane kakhulu.
- Isici esivame kakhulu ukuba mude kunomlingiswa ojwayelekile.
- Lesi simo asivamile ukubangela ukukhubazeka kwengqondo.
- Uma ingane inezinkinga ezifana nokubambezeleka ekukhuleni kwenkulumo noma kwemisipha, ukuhlonza kusenesikhathi kanye nokwelashwa okufanele kanye nokusekelwa kungenza umehluko omkhulu. Khuluma nodokotela wakho nganoma yiziphi izinkinga.
I-XYY syndrome, i-Jacob syndrome, i-extra Y chromosome, izifo zofuzo, i-Karyotype, izingane zesilisa, ukubambezeleka kokukhula
