Abantwana bethu bonke bahlukile kwaye bahlukile. Ngamanye amaxesha oku kuhlukile kuvela kwiijini zabo, oko kukuthi, ekuzalweni. Namhlanje siza kuthetha ngemeko ebangelwa lutshintsho olunjalo lwezakhi zofuzo, kodwa kungathethwa kakhulu ngayo kuluntu. Oko kukuthi, iiseli zomfana zine-chromosome eyongezelelweyo ye-Y, okanye ngokwezonyango, i-XYY syndrome. Musa ukoyika xa usiva oku, masiqonde yonke into ngayo ngokulula.
Kutheni oku kusenzeka? Yintoni ebangela i-XYY syndrome?
Ngamafutshane, iseli nganye emzimbeni wethu inento ebizwa ngokuba zii-chromosomes . Zicinge njengeencwadi zemiyalelo ezakha imizimba yethu. Ngokwesiqhelo, iseli nganye inezi ncwadi zemiyalelo, okanye ii-chromosomes ezingama-46. Sizifumana ezi ngababini abangama-23. Sifumana enye kwisibini ngasinye, enye kumama wethu kwaye enye kutata wethu.
Kwezi zibini zingama-23, ezokuqala ezingama-22 zimisela zonke ezinye iimpawu zomzimba wethu. Isibini sama-23 simisela isini sethu. Kwimeko yentombazana, esi sibini singu-XX, kwaye kwimeko yenkwenkwe, singu-XY.
Nantsi indlela eyenzeka ngayo i-XYY syndrome. Xa umntwana ekhulelwa, kwenzeka impazamo encinci ekwakhiweni kwesidoda sikatata, nto leyo ebangela ukuba kongezwe i-chromosome eyongezelelweyo ye-Y kweso sidoda. Oku kubizwa ngokuba yi-nondisjunction kwisayensi yezonyango. Emva koko, yonke iseli emzimbeni womntwana oyinkwenkwe ozelwe kweso sidoda iqulethe indibaniselwano ye-chromosome ye-XYY endaweni ye-XY eqhelekileyo.
Into ebalulekileyo kukuba oku akubangelwa ngumama okanye ngutata . Kwakhona, akubangelwa yimfuza. Oko kukuthi, utata one-XYY syndrome akayi kuyidlulisela le meko kunyana wakhe.
Zithini iimpawu zomzimba zomntwana one-XYY syndrome?
Le yingxaki yokwenyani kubantu abaninzi. Kodwa inyani yile, ayingabo bonke abafana abane-XYY syndrome ababonisa umahluko omkhulu emzimbeni. Ngamanye amaxesha, akukho zimpawu zikhethekileyo ezibonakalayo.
Uhlobo lwethu lwemfuza luludwe lwemiyalelo eyenza imizimba yethu. Olu hlobo lwemfuza, kunye nendawo esihlala kuyo, lumisela iimpawu zethu zangaphandle (ii-phenotype) ezifana nobude, ubunzima, kunye nenkangeleko.
Nangona kunjalo, kukho iimpawu zomzimba ezinokuthi ngamanye amaxesha zinxulunyaniswe nale meko. Kodwa khumbula, ayizizo zonke ezi mpawu ezisebenza kuye wonke umntu.
| Iimpawu zomzimba | Ingcaciso elula |
|---|---|
| Ukuba mde kunomndilili | Olu lolona phawu luxhaphakileyo. Basenokuba bade kunabanye abantu kusapho. |
| Intloko enkulu namazinyo | Intloko namazinyo zinokuba zikhulu kakhulu xa kuthelekiswa nobukhulu bomzimba. |
| Iinyawo ezithe tyaba | Ukungabikho kwegophe eliqhelekileyo kumqolo ongezantsi. |
| Umgama omkhulu phakathi kwamehlo | Umgama phakathi kwamehlo mkhulu kancinci kunowesiqhelo. |
| I-Scoliosis | Kukho ithuba lokuba umqolo ugobe ecaleni. |
| Ukwandiswa kwamasende | Amanye amasende abantwana anokuba makhulu kunesiqhelo. |
Njengoko bekutshiwo ngaphambili, ukuba mde kunomndilili lolona phawu luxhaphakileyo phakathi kwaba bantu. Uphando lufumanise ukuba aba bantu banekopi eyongezelelweyo ye -SHOX gene kwii-chromosomes zethu zesini, nto leyo ebangela ukukhula kwamathambo ngokukhawuleza, ingakumbi emalungwini.
Uninzi lwamadoda ane-XYY syndrome anokukhula okuqhelekileyo ngokwesondo kunye namanqanaba e -testosterone , ngoko ke ayakwazi ukuba nabantwana . Nangona kunjalo, inani elincinci kakhulu lamadoda linokuba neengxaki zokuzala.
Ziziphi iimpawu ezinxulumene nale meko?
I-XYY syndrome inokunxulunyaniswa neemeko ezithile zempilo kunye nobunzima bokufunda. Nangona kunjalo, uhlobo lwezi mpawu luyahluka kakhulu kumntu nomntu. Nangona abanye benokuba nazo kancinci, abanye banokuchaphazeleka kakhulu.
| Udidi lweempawu | Iimeko ezinokwenzeka |
|---|---|
| Ukulibaziseka kophuhliso | |
| Izakhono zokuqhuba imoto | Ukulibaziseka okuncinci kwizinto ezifana nokuhlala, ukuhamba, njl. Imisipha esezantsi. |
| Ukulibaziseka kwentetho | Ukulibaziseka ekuqaliseni ukuthetha okanye ezinye iingxaki zokuthetha. |
| Iingxaki zokufunda nokuziphatha | |
| Ubunzima bokufunda | Ukuba nobunzima bokufunda nokubhala. |
| Iipateni zokuziphatha | I-ADHD (Ingxaki Yokungakwazi Ukuqwalasela), Ingxaki Yokungazinzi Kwengqondo Encinci, Ixhala, Ukungaphumli. |
| Ezinye iingxaki zempilo | |
| Iimeko zomzimba | Isifuba, ukuxhuzula, ukungcangcazela kwezandla. |
Nantsi into ekufuneka siyikhumbule sonke: Ukukhubazeka kwengqondo .Ukukhubazeka kwengqondo akuyonto ixhaphakileyo kwi-XYY syndrome. Inqanaba lobukrelekrele laba bantwana lidla ngokuba ngaphakathi komlinganiselo oqhelekileyo.
Ifunyanwa njani i-XYY syndrome?
Le meko ingafunyanwa ngovavanyo olwenziwe ngaphambi kokuba umntwana azalwe, oko kukuthi, ngexesha lokukhulelwa , kunye novavanyo olwenziwe nakweyiphi na iminyaka emva kokuzalwa.
- Ngexesha lokukhulelwa: Le meko inokuchongwa ngovavanyo olukhethekileyo lwemfuza olufana ne -Amniocentesis okanye i-Chorionic Villus Sampling eyenziwa kumama okhulelweyo.
- Emva kokuzalwa: Uvavanyo lwe-karyotype ludla ngokwenziwa. Olu luvavanyo lwegazi olulula. Lunokuchonga ngokuchanekileyo inani lee-chromosomes kwiiseli zethu kunye nokulungelelana kwazo.
Nje ukuba le meko ichongiwe, ukuba umntwana wakho unengxaki yokuthetha okanye izakhono zakhe zokushukuma komzimba ziyalibaziseka, unyango olukhethekileyo kunye nenkxaso yemfundo inokunceda. Thetha nogqirha wakho ngale nto kwaye, ukuba kuyimfuneko, mthumele kugqirha wabantwana, kwingcali yemfuza, okanye kwingcali yophuhliso.
Enyanisweni, ipesenti enkulu yamadoda ane-XYY syndrome emhlabeni aphila ubomi bawo bonke engazi. Oku kungenxa yokuba akanazo iimpawu ezibonakalayo.
Umyalezo Wokuya Ekhaya
- I-XYY syndrome yimeko yemfuza eyenzeka ngokungacwangciswanga. Ayibangelwa yimpazamo yomzali okanye ayizuzwa njengelifa kwizizukulwana ngezizukulwana.
- Uninzi lwabafana nabantu abadala baphila ubomi obusempilweni nobuqhelekileyo ngaphandle kweempawu okanye iimpawu ezibuthathaka kakhulu.
- Uphawu oluqhelekileyo kukuba mde kunomndilili.
- Le meko ayisoloko ibangela ukukhubazeka kwengqondo.
- Ukuba umntwana uneengxaki ezifana nokulibaziseka ekuphuhlisweni kwentetho okanye kwemisipha, ukuchongwa kwangethuba kunye nonyango olufanelekileyo kunye nenkxaso kunokwenza umahluko omkhulu. Thetha nogqirha wakho ngayo nayiphi na into ekuxhalabisayo.
I-XYY syndrome, i-Jacob syndrome, i-extra Y chromosome, izifo zemfuza, i-Karyotype, abantwana abangamadoda, ukulibaziseka kokukhula
