Hore o ithuta liphatsa tsa lefutso tsa bongaka

Liphatsa tsa lefutso - ea saense hore o ithuta thepa ea lintho tse phelang tse kang lefutso le phetoho. E le o tsejoa, le tšobotsi e ka sehloohong ea lintho tsa tlhaho hore distinguishes e tsoa ho e le ba shoeleng - le matla a ho ikatisa. Tšobotsi e 'ngoe ea bohlokoa, o ile a bua ka hore ke lefutso, ke repeatability sa t. E. Bokhoni ba tsoalang mofuta ba bona. Ka kakaretso, le baemeli ba mofuta ofe kapa ofe tse ngata tse tšoanang le baholo-holo ba bona e le letsoalloa, ho feta motho ka mong tse ling tsa mefuta e tšoanang.

Empa hore e mong le mefuta e na le boemo ba itseng ba volatility, hobane esita le bara le barali babo ha likopi tse tobileng. Bobeli lintlha - lefutso le phetoho - lithuto tsa saense tsa likokoana-hloko tsa liphatsa tsa lefutso, e leng e na le, le eena, dikarolo tsa ba tloaelehileng le ya poraefete. Ha ntho e ithuta, partitions kakaretso ho etsa lipatlisiso le liphatsa tsa lefutso tse metheo ea lefutso, ho and analysis ea DNA, sebōpeho sa liphatsa tsa lefutso le liphetoho liphatseng tsa lefutso tsa bona, le dikarolo poraefete di e nehetsoeng ho khetholla dipaterone ho tloaelehile mefuta e fapaneng ea lintho tse phelang.

Liphatsa tsa lefutso tsa botho - Lebisang dikarolo poraefete. Bao e leng ba le puisano e lona, e amanang le bolwetse motho, lefapha la bongaka le liphatsa tsa lefutso lithuto. Sepheo se seholo sa hore lekala ena ea saense - khethollang karolo ea motsoako o le liphatsa tsa lefutso tse ka tšimoloho le tsela ea mafu a sa tšoaneng.

Mafu a hore o ithuta liphatsa tsa lefutso tsa bongaka, ba aroloa ka lefa sebele le multifactorial. Tsa pele kenyeletsa chromosomal (bakileng ka ho fetola lenane la chromosomes kapa sebopeho bona) le phatsa ea lefutso (e loketseng ho liphetoho liphatseng tsa lefutso phatsa ea lefutso) lefu. Ha phetoho liphatseng tsa lefutso ke le teng ka phatsa ea lefutso le 'ngoe feela, lefu lena le bitsoa monogenic.

Bitsoa mafu multifactorial bakeng sa eo ho eona ho ke predisposition liphatsa tsa lefutso. Tsena li akarelletsa ho fetisisa ya mafu a tsebahalang ka bomong. Ka ketsahalo ea mafu joalo ka motho oa nama, ntle le a sa thabiseng tšusumetso e ntle, ho fana ka boemo sete ya liphatsa tsa lefutso e ka tšoana le ho ba mashome 'me ba makholo.

liphatsa tsa lefutso tsa bongaka ka saense e ka o ne a rerile ho hlahloba mafu a lefa, ho itšoara le ho hlahloba ata bona ka lihlopha tse fapaneng tsa sechaba le tsa merabe, a eletsa bakuli le malapa a bona, ho thibela mafu a lefa, ho ithuta pathogenesis le etiology ba joalo.

Bakeng sa thibelo ea mafu a lefa liphatsa tsa lefutso tsa tleleniki sebedisa prenatal botlaaseng (m. E. Antenatal) tlhathoba. Mosebetsi oa ho lingaka - ka nako e loketseng boitsebiso mabaka khoneha pathogenic le tekanyetso ya kotsing ea itseng mafu a ka ngoana ea e-s'o hlahe, e thehiloeng boemo ba bophelo bo botle ba batsoali ba ka khona. Ka hona ke ntho ea bohlokoa haholo-holo bakeng sa banyalani ba bang ba lebeletse ngoana kapa rera feela ho li nahanang, feta tlhahlobo e qaqileng ea boemo ba bophelo ba bona le ho khetholla lintlha tsohle kotsing. Ho akarelletsa le ea bohlokoa ho tseba le ho tsebisa lingaka ka o teng ka lapeng (bobeli ka ntate oa nakong e tlang, 'me ka lehlakoreng la' mè oa hae), mafu a lefa le ho tse ling tse joalo.

Linaheng tse tsoetseng pele, liphatsa tsa lefutso le meriana sebetsa inseparably. Thahasello ea bophelo nakong e tlang ba molekane oa ka (mosali) le ho ba teng ka lapeng la mafu a lefa entse telele pele ho lenyalo. Linaheng tse ling, lengolo tsa bongaka ke tokomane e tlamang bakeng sa ngodiso ya lenyalo.

Lilemong tsa morao tjena, liphatsa tsa lefutso tsa bongaka e entse le katleho e kholo ka ntshetsopeleng lona. Katleho ka sehloohong e ne e le deciphering tsa liphatsa tsa lefutso tsa botho, le boitsebiso ba liphatsa tsa lefutso le tsohle le ho hlwaya mofuta limolek'hule liprotheine haholo. Joale bo-rasaense ba ba ka mafolofolo ho ithuta ka kamano ea liphatsa tsa lefutso e fapaneng le mafu a itseng nakong e tlang litšepiso ntshetsopele ya feletseng ntjha phekolo mafu liphatsa tsa lefutso le ho thibela mafu a batho tseo monna ke le tsekamelo ea.

Mosebetsi oa ho ngaka leha e le efe ba tšoanelehang - mathoasong a boitsebahatso ea bakuli le bolwetse ea tlhaho lefa, beha lintho tsa tlhaho tsa eona le tataiso ea mamello ho e loketseng ho tse bohareng tsa bongaka-liphatsa tsa lefutso.
