Ubuthakathaka beTay-Sachs yini? Izimpawu, Izimbangela, & Ukwelashwa

Ubuthakathaka beTay-Sachs yisimo esingavamile sezofuzo esithinta uhlelo lwezinzwa, ikakhulukazi lapho umzimba ungakwazi ukukhiqiza okwanele kwesenzakalo esibalulekile esibizwa nge-hexosaminidase A. Le nsenzakalo ivame ukusiza ekuqhekekeni kwezinto ezinamaswishi ezisemisebeni yezinzwa, kodwa uma ingapheli noma isebenzi kahle, lezi zinto ziyaqoqana bese konakalisa kancane kancane uhlelo lwezinzwa.

Nakuba lesi simo sikubi futhi sishintsha impilo, ukuqonda ukuthi kusho ukuthini kungasiza imindeni ukuthi iqhubeke nohambo lwabo ngokucaca nangokusekelwa okukhulu. Izimo eziningi zivele ebuntwaneni, nakuba ezinye izinhlobo zingathuthuka kamuva ebuntwaneni noma ngisho nasebudaleni.

Ziyini izimpawu zokuthakathaka kweTay-Sachs?

Izimpawu zokuthakathaka kweTay-Sachs zihluka kakhulu kuye ngokuthi isimo siqala nini ukuzibonakalisa. Ngokuvamile, izimpawu zivele ezinyangeni ezimbalwa zokuqala zokuphila komntwana, kodwa isikhathi nesimo singahluka kusuka kumntwana kuya komunye.

Esikweni esivamile, esibizwa ngokuthi yi-infantile Tay-Sachs, ungase uqaphele lezi zinguquko zokuqala kumntwana wakho:

• Ukulahlekelwa amakhono ayesevele ewafundile, njengokulala noma ukufinyelela emidlalweni
• Ukuncipha kokuzwa imisindo, lapho imisindo evamile ingase ibabambe kakhulu kunokujwayelekile
• Ubuthakathaka bemisipha obuenza kube nzima ukuhamba
• Izinkinga zobuso, kufaka phakathi isikhala esibomvu esibomvu esingabonwa odokotela ngesikhathi sokuhlolwa kwamehlo
• Ubunzima bokuginya nezinselele zokudla
• Ukuhlupheka okungase kuqhubeke ngokuqhubekayo ngokuhamba kwesikhathi

Okwenza lokhu kube inselele ngokukhethekile emindenini ukuthi abantwana bavame ukubonakala bekhula kahle ekuqaleni, bese kancane kancane belahlekelwa amakhono abengawazuze. Lokhu kuqhubeka kungaba buhlungu ukukubona, kodwa ukwazi ukuthi yini okulindelekile kungakusiza unikeze ukunakekelwa nokusekela okuhle kunakho konke.

Ngokungavamile, i-Tay-Sachs ingabonakala kamuva ebuntwaneni noma ebudaleni. Lezi zinhlobo zivame ukuqhubeka kancane futhi zingabandakanya izimpawu ezinjengobunqunu bemisipha, ubunzima bokukhuluma, kanye nezinguquko ekuhlanganiseni noma emakhono okucabanga.

Ziyini izinhlobo zesifo se-Tay-Sachs?

I-Tay-Sachs inesizinda sezinhlobo ezahlukene, ngayinye iboniswa ukuthi izimpawu ziqala nini nokuthi ziqhubeka ngokushesha kangakanani. Ukuqonda lezi zinhlobo kungakusiza ukwazi ukuthi yini okulindelekile nokuhlela izidingo zomndeni wakho.

Uhlobo lwengane yilona elivamile kakhulu, lithinta cishe u-80% lwabantu abane-Tay-Sachs. Izimpawu zivame ukuqala phakathi nezinyanga eziyi-3 kuya kwezi-6 ubudala, futhi abantwana abanelilo hlobo bavame ukuba namanqanaba aphansi kakhulu e-enzyme ye-hexosaminidase A.

I-Tay-Sachs yentsha ibonakala phakathi kweminyaka eyi-2 kuya kweyi-10. Abantwana abanelilo hlobo bavame ukuthuthuka kahle ekuqaleni, bese behlushwa ukwehluleka kancane kancane kwamakhono omoto, ubunzima bokukhuluma, kanye nezinguquko zokuziphatha. Leli hlobo liqhubeka kancane kunohlobo lwengane.

I-Tay-Sachs eqala ebudaleni, ebizwa nangokuthi i-late-onset, ingabonakala noma kuphi kusukela eminyakeni yobusha kuya ebudaleni. Abantu abanelilo hlobo bavame ukuba nomsebenzi othile we-enzyme osele ukhona, okuvumela ukuqhubeka kancane kakhulu. Izimpawu zingabandakanya ubuthakathaka bemisipha, ubunzima bokuhlanganisa, futhi ngezinye izikhathi izimpawu ze-psychiatric ezinjengokucindezeleka noma ukukhathazeka.

Kukhona futhi uhlobo oluyimfihlo kakhulu oluthiwa yi-chronic GM2 gangliosidosis, elingaba nezimpawu ezahlukene nezinga lokuqhubeka. Uhlobo ngalunye lubonisa amazinga ahlukene womsebenzi we-enzyme, okuchaza ukuthi kungani isikhathi nobunzima bezimpawu kungase kuhluke kakhulu phakathi kwabantu.

Yini ebangela isifo se-Tay-Sachs?

Isifo se-Tay-Sachs sibangelwa yizinguquko, ezibizwa ngokuthi yi-mutations, ku-gene ethile eyaziwa ngokuthi yi-HEXA. Le gene inikeza imiyalo yokwenza i-enzyme ye-hexosaminidase A, okuyinto umzimba wakho oyidingayo ukuze uqhekeze izinto ezinhlanzi ezibizwa nge-GM2 gangliosides ezicellini zezinzwa.

Uma kokubili amakhophi e-HEXA gene enezinguquko, umzimba wakho awukwazi ukukhiqiza i-enzyme eyanele esebenzayo. Lokhu kusho ukuthi i-GM2 gangliosides iqala ukuqoqana ezicubu zezinzwa, ikakhulu ebuchosheni nasemgogweni wamathambo, kancane kancane ibangele ukulimala ngokuhamba kwesikhathi.

Lesi simo silandela lokho odokotela abakubiza ngokuthi iphethini yokudluliselwa kwe-autosomal recessive. Lokhu kusho ukuthi bobabili abazali kufanele babe nekopi yomjikelezo olugulayo ukuze ingane yabo ithuthukise isifo se-Tay-Sachs. Uma bobabili abazali bayizithwali, ukukhulelwa ngakunye kunesilinganiso se-25% sokuthi kuzokhiqiza ingane enalesi simo.

Kubalulekile ukuqonda ukuthi ukuba yisithwali akusho ukuthi uzokuthuthukisa lesi sifo ngokwakho.
