Hloov chaw nqes syndrome yog hom Down syndrome uas yog tshwm sim thaum ib tug chromosome tawg tawm thiab txuas rau lwm tus chromosome . Hauv kev hloov chaw nqes syndrome ,ua 21 chromosome tuaj yeem txuas rau 14 chromosome , los yog lwm yam chromosome cov lej zoo li 13, 15, lossis 22.
Hais txog qhov no, koj yuav ua li cas paub yog tias koj muaj translocation?
Kev kuaj rau chromosome kev hloov chaw Kev tshuaj ntsuam genetic muaj nyob rau nrhiav seb tus neeg nqa ib kev hloov chaw . Kev kuaj ntshav yooj yim yog ua tiav, thiab cov hlwb los ntawm cov ntshav yog kuaj nyob rau hauv ib lub chaw soj nstuam saib xyuas qhov kev npaj ntawm cov chromosomes. Qhov no yog hu ua karyotype test.
Kuj Paub, piv txwv ntawm kev hloov pauv yog dab tsi? Lub sij hawm kev hloov chaw yog siv thaum qhov chaw ntawm cov khoom siv chromosome hloov. Muaj ob hom tseem ceeb ntawm kev hloov chaw : Reciprocal thiab Robertsonian. Qhov tshiab chromosome no hu ua kev hloov chaw chromosome. Cov kev hloov chaw hauv qhov no piv txwv yog nyob nruab nrab ntawm chromosomes 14 thiab 21.
Ua li no, qhov txawv ntawm trisomy 21 thiab translocation Down syndrome yog dab tsi?
Tsis muaj qhov loj qhov sib txawv ntawm cov neeg mob uas muaj Translocation Down Syndrome piv nrog cov neeg uas muaj 3 cov ntawv luam ntawm chromosome 21 . Qhov no hu ua trisomy 21 . Tus niam txiv ntawd yuav muaj 45 tag nrho cov chromosomes hauv txhua lub cell ntawm lub cev, tab sis niam txiv yuav zoo li qub thiab noj qab nyob zoo.
Translocation ua rau dab tsi?
Reciprocal translocation yog chromosome abnormality ua rau los ntawm kev sib pauv ntawm qhov chaw ntawm non-homologous chromosomes. Lub gene fusion yuav raug tsim thaum lub kev hloov chaw koom nrog ob lub noob sib cais. Nws yog kuaj pom ntawm cytogenetics lossis karyotype ntawm cov hlwb cuam tshuam.

Nws tuaj yeem kuaj pom nrog amniocentesis - ib txoj kev kho mob ua ntej yug menyuam siv los kuaj xyuas caj ces thiab chromosomal teeb meem
Dab tsi yog chromosomal translocation ua rau?
Hauv cov noob caj noob ces, chromosome translocation yog qhov tshwm sim uas ua rau muaj qhov txawv txav ntawm chromosomes. Reciprocal translocation yog chromosome abnormality tshwm sim los ntawm kev sib pauv ntawm qhov chaw ntawm cov chromosomes uas tsis yog homologous. Ob qhov sib cais ntawm ob chromosomes sib txawv yog hloov
