Abaana baffe bonna ba njawulo era ba njawulo. Oluusi enjawulo eno eva mu buzaale bwazo, kwe kugamba, okuva mu kuzaalibwa. Leero tugenda kwogera ku mbeera ereetebwa enkyukakyuka mu buzaale bwetyo, naye nga teyogerwako nnyo mu bantu. Kwe kugamba, obutoffaali bw’omulenzi bulina ekirungo kya Y eky’enjawulo oba mu ngeri y’obusawo, obulwadde bwa XYY. Totya nga owulira bino, ka tutegeere buli kimu ekikikwatako mu ngeri ennyangu.
Lwaki kino kibaawo? Kiki ekivaako obulwadde bwa XYY?
Mu ngeri ennyangu, buli katoffaali mu mubiri gwaffe kalina ekintu ekiyitibwa chromosomes . Zilowoozeeko ng’ebitabo ebiyigiriza ebizimba emibiri gyaffe. Mu budde obwabulijjo, buli butoffaali bwaffe bulina ebitabo bino eby’ebiragiro oba chromosomes 46. Bino tubifuna mu babiri 23. Tufuna emu okuva mu buli pair, emu okuva ku maama waffe ate endala okuva ku taata waffe.
Ku babiri bano 23, babiri 22 abasooka be basalawo engeri endala zonna ez’omubiri gwaffe. Ababiri ba 23 be basalawo ekikula kyaffe . Mu muwala, pair eno eba XX, ate mu mulenzi, eba XY.
Laba engeri obulwadde bwa XYY syndrome gye bubaawo. Omwana bw’afuna olubuto, ensobi entonotono ebaawo mu kutondebwa kw’ensigo za taata, ekivaako okugattibwako ekirungo kya Y eky’enjawulo ku nsigo eyo. Kino kiyitibwa nondisjunction mu sayansi w’obusawo. Olwo, buli katoffaali mu mubiri gw’omwana omusajja azaalibwa okuva mu nsigo eyo kalimu omugatte gwa XYY chromosome mu kifo kya XY eya bulijjo.
Ekikulu kino si nsobi ya maama oba taata . Ate era, si mbeera ya nsikirano. Kwe kugamba, taata alina obulwadde bwa XYY embeera eno tajja kugiyisa mu mutabani we.
Engeri ki ez’omubiri gw’omwana alina obulwadde bwa XYY?
Kino kizibu kya ddala eri abantu bangi. Naye ekituufu kiri nti abalenzi bonna abalina obulwadde bwa XYY si balaga enjawulo nnene mu mubiri. Oluusi, tewali kintu kya njawulo wadde kyeyoleka.
Genotype yaffe ye set y’ebiragiro ebikola omubiri gwaffe. Ensengeka eno ey’obuzaale, awamu n’obutonde bwe tubeera, bye bisalawo engeri zaffe ez’ebweru (phenotype) ng’obuwanvu, obuzito, n’endabika.
Kyokka waliwo obubonero obumu obw’omubiri oluusi obuyinza okukwatagana n’embeera eno. Naye jjukira nti obubonero buno bwonna tebukwata ku buli muntu.
| Engeri y’omubiri | Ennyinyonnyola ennyangu |
|---|---|
| Okubeera omuwanvu okusinga ku wa bulijjo | Eno y’engeri esinga okubeerawo. Bayinza okuba nga bawanvu okusinga ab’omu maka amalala. |
| Omutwe omunene n’amannyo | Omutwe n’amannyo bisobola okuba ebinene ennyo okusinziira ku bunene bw’omubiri. |
| Ebigere ebipapajjo | Obutabeerawo kwa curve eya bulijjo mu mugongo ogwa wansi. |
| Ebanga erisingawo wakati w’amaaso | Ebanga wakati w’amaaso lisingako katono ku lya bulijjo. |
| Obulwadde bwa scoliosis | Waliwo okusobola okukoona kw’omugongo mu mabbali. |
| Okugaziwa kw’ensigo | Ensigo z’abaana abamu ziyinza okuba ennene okusinga eza bulijjo. |
Nga bwe kyayogeddwako emabegako, okubeera omuwanvu okusinga ku wa bulijjo y’engeri esinga okubeera mu bantu bano. Okunoonyereza kuzudde nti abantu bano balina kkopi ey’enjawulo ey’obuzaale bwa SHOX ku chromosomes zaffe ez’okwegatta, ekivaako amagumba okukula amangu , naddala mu bitundu by’omubiri.
Abasajja abasinga abalina obulwadde bwa XYY balina enkula ya bulijjo mu kwegatta n’obusimu obuyitibwa testosterone , kale basobola okuzaala abaana. Kyokka abasajja abatono ennyo bayinza okufuna obuzibu mu kuzaala.
Bubonero ki obukwatagana n’embeera eno?
Obulwadde bwa XYY buyinza okukwatagana n‟embeera z‟obulamu ezimu n‟obuzibu mu kuyiga. Kyokka obutonde bw’obubonero buno bwawukana nnyo okusinziira ku muntu. Wadde ng’abamu bayinza okubifuna mu ngeri etali ya maanyi nnyo, abalala bayinza okukosebwa ennyo.
| Ekika ky’obubonero | Embeera eziyinza okubaawo |
|---|---|
| Okulwawo kw’enkulaakulana | |
| Obukugu mu kukola emirimu gy’omubiri | Okulwawo katono mu bintu ng’okutuula, okutambula n’ebirala.. Low muscle tone. |
| Okulwawo okwogera | Okulwawo okutandika okwogera oba okulemererwa kw’okwogera okumu. |
| Ebizibu mu kuyiga n‟enneeyisa | |
| Ebizibu mu kuyiga | Okubeera n’obuzibu obumu mu kusoma n’okuwandiika. |
| Enkola z’enneeyisa | ADHD (Obulwadde bw’okulemererwa okukola ennyo), Obuzibu bwa Autism Spectrum Obuzibu, Okweraliikirira, Obutawummula. |
| Ebizibu ebirala eby’obulamu | |
| Embeera z’omubiri | Asima, okukonziba, okukankana kw’emikono. |
Wano waliwo ekintu ffenna kye tulina okujjukira: Obulemu ku mageziObulemu ku magezi si kintu kya bulijjo mu bulwadde bwa XYY. Omutindo gw’amagezi g’abaana bano gutera okuba mu bbanga erya bulijjo.
Obulwadde bwa XYY buzuulibwa butya?
Embeera eno esobola okuzuulibwa nga tuyita mu kukeberebwa okukolebwa nga omwana tannazaalibwa, kwe kugamba, ng’ali lubuto , awamu n’okuyita mu kukeberebwa okukolebwa ku myaka gyonna oluvannyuma lw’okuzaalibwa.
- Mu kiseera ky’olubuto: Embeera eno esobola okuzuulibwa ng’oyita mu kukeberebwa okw’enjawulo okw’obuzaale nga Amniocentesis oba Chorionic Villus Sampling okukolebwa ku maama ali olubuto.
- Oluvannyuma lw’okuzaalibwa: Okukebera karyotype kusinga kukolebwa. Kino kyangu okukebera omusaayi. Kisobola okuzuula obulungi omuwendo gwa chromosomes mu butoffaali bwaffe n’ensengeka yazo.
Embeera eno bw’emala okuzuulibwa, singa omwana wo alwawo okwogera oba okulwawo mu kukola emirimu gy’omubiri, obujjanjabi obw’enjawulo n’obuyambi mu kusomesa bisobola okuyamba. Yogerako n’omusawo wo ku nsonga eno era bwe kiba kyetaagisa, baweereze ew’omusawo w’abaana, omukugu mu by’obuzaale oba omukugu mu nkula.
Mu butuufu, abasajja bangi ku buli kikumi abalina obulwadde bwa XYY mu nsi yonna bawangaala obulamu bwabwe bwonna nga tebakimanyi. Kino kiri bwe kityo kubanga tebalina bubonero bwonna bulabika.
Obubaka Obutwala Awaka
- Obulwadde bwa XYY mbeera ya buzaale ebaawo mu ngeri ey’ekifuulannenge. Tekiva ku nsobi ya muzadde oba okusikira okuva ku mulembe okudda ku mulala.
- Abalenzi n’abantu abakulu abasinga babeera mu bulamu bulungi, obwa bulijjo nga tebalina bubonero oba obubonero obutono ennyo.
- Engeri esinga okumanyibwa kwe kuba omuwanvu okusinga ku wa bulijjo.
- Embeera eno tetera kuleeta bulemu bwa magezi.
- Singa omwana aba n‟ebizibu ng‟okulwawo okwogera oba okukula kw‟enkola y‟omubiri, okuzuula amangu n‟obujjanjabi obutuufu n‟okumuwa obuyambi kiyinza okuleeta enjawulo nnene. Yogerako n’omusawo wo ku kintu kyonna ekikweraliikiriza.
