Lub karyotype xeem yog dab tsi?

Qhov kev ntsuam xyuas karyotype saib qhov loj me, cov duab, thiab tus lej ntawm koj lub chromosomes. Cov chromosomes yog cov ntu ntawm koj lub hlwb uas muaj koj cov noob caj noob ces. Cov noob yog cov seem ntawm DNA tso tawm los ntawm koj niam thiab koj txiv. Lawv nqa cov ntaub ntawv uas txiav txim siab koj cov xeeb ceem tshwj xeeb, xws li qhov siab thiab xim qhov muag.

Tib neeg ib txwm muaj 46 chromosomes, muab faib ua 23 khub, nyob hauv txhua lub cell. Ib nkawm ntawm ob tug khub yog los ntawm koj niam, thiab lwm tus khub los ntawm koj txiv.

Yog tias koj muaj ntau dua lossis tsawg dua cov chromosomes ntau dua 46, lossis yog tias muaj dab tsi txawv ntawm qhov loj lossis cov qauv ntawm koj cov chromosomes, nws tuaj yeem txhais tau tias koj muaj caj ces. Kev sim ntsuas kab mob karyotype feem ntau siv txhawm rau pab txhawm rau txhawm rau nrhiav kev tshuaj ntsuam tsis zoo ntawm cov menyuam mos.

Lwm lub npe: kev tshuaj ntsuam genetic sim, kev sim tshuaj chromosome, kev kawm chromosome, kev tshuaj ntsuam cytogenetic

Nws siv rau dab tsi?

Kev ntsuas ntsuas karyotype yuav siv tau rau:

  • Txheeb xyuas tus menyuam tseem tsis tau yug los rau kev mob caj ces
  • Kev kuaj mob muaj raws caj ces hauv tus menyuam lossis menyuam yaus
  • Tshawb nrhiav seb puas muaj keeb tiv thaiv chromosomal tiv thaiv tus poj niam kom tsis txhob xeeb tub lossis ua rau nchuav menyuam
  • Kuaj xyuas ib tus menyuam tseem nyob (menyuam uas tuag qeeb rau cev xeeb tub lossis thaum yug) kom pom tias lub qog chromosomal puas ua rau ploj tuag
  • Saib seb koj puas muaj mob caj ces yuav kis tau rau koj cov menyuam
  • Kev kuaj mob lossis ua lub phiaj xwm kho mob rau qee yam mob qog noj ntshav thiab ntshav tsis zoo

Vim li cas kuv thiaj yuav tsum tau kuaj cov karyotype?

Yog tias koj xeeb tub, koj yuav xav kuaj karyotype rau koj tus menyuam tseem tsis tau yug yog tias koj muaj qee yam txaus ntshai. Cov no suav nrog:


  • Koj lub hnub nyoog. Tag nrho txoj kev pheej hmoo ntawm kev mob caj ces yug muaj tsawg, tab sis qhov kev pheej hmoo siab dua rau cov poj niam uas muaj menyuam yaus hnub nyoog 35 lossis laus dua.
  • Keeb kwm tsev neeg. Koj txoj kev pheej hmoo yuav nce ntxiv yog tias koj, koj tus khub, thiab / lossis lwm tus ntawm koj cov menyuam muaj caj ces tsis zoo.

Koj tus menyuam lossis tus menyuam yaus yuav xav tau kev kuaj yog tias nws muaj cov cim qhia txog tus mob caj ces tsis zoo. Muaj ntau ntau yam mob caj ces, muaj txhua cov tsos mob sib txawv. Koj thiab koj tus kws kho mob tuaj yeem tham txog seb puas yuav tsum tau kuaj xyuas.

Yog tias koj yog poj niam, koj yuav tsum tau kuaj karyotype yog tias koj muaj teeb meem cev xeeb tub los yog muaj me nyuam hauv plab ntau. Thaum ib qho nchuav menyuam tsis tshua pom tshwm, yog tias koj tau muaj ob peb zaug, nws yuav yog vim muaj teeb meem chromosomal.

Koj tseem yuav xav tau kev kuaj mob karyotype yog tias koj muaj cov tsos mob ntawm lossis tau muaj tus neeg muaj ntshav siab, ntshav ntawm lub cev, lossis mob myeloma, lossis qee yam kev ua haujlwm ntshav. Cov kev tsis zoo no tuaj yeem ua rau chromosomal hloov pauv. Pom cov kev hloov pauv no tuaj yeem pab koj tus kws kho mob txheeb xyuas, soj ntsuam, thiab / lossis kho tus kab mob.


Yuav ua li cas thaum lub sijhawm ntsuas karyotype?

Txog kev ntsuas kev ntsuas karyotype, koj tus kws kho mob yuav xav coj cov qauv ntawm koj lub hlwb. Txoj hauv kev zoo tshaj plaws kom tau txais cov qauv suav nrog:

  • Kuaj ntshav. Rau txoj kev ntsuas no, tus kws saib xyuas kev noj qab haus huv yuav ntsuas ntshav ntawm txoj leeg hauv koj txhais caj npab, siv rab koob me me. Tom qab cov koob raug tso nkag, cov ntshav me me yuav raug sau rau hauv lub khob kuaj lossis vial. Koj tuaj yeem hnov ​​me ntsis thaum cov koob nkag mus lossis tawm. Qhov no feem ntau yuav siv sijhawm tsawg dua tsib feeb.
  • Kev kuaj cev xeeb tub nrog amniocentesis lossis chorionic villus sampling (CVS). Chorionic villi yog cov kev loj hlob me me uas pom hauv lub placenta.

Txog amniocentesis:

  • Koj yuav tau pw ntawm koj sab nraum qab ntawm lub rooj kuaj mob.
  • Koj tus kws kho mob yuav tshem cov cuab yeej siv hla koj lub plab. Ultrasound siv suab tsis zoo los kuaj xyuas qhov chaw ntawm koj lub tsev menyuam, me nyuam, thiab menyuam.
  • Koj tus kws kho mob yuav muab rab koob me me tso rau hauv koj lub plab thiab thim tawm cov kua txiv amniotic me me.

Amniocentesis feem ntau ua rau nruab nrab ntawm lub lim tiam 15 txog 20 ntawm cev xeeb tub.


Rau CVS:

  • Koj yuav tau pw ntawm koj sab nraum qab ntawm lub rooj kuaj mob.
  • Koj tus kws kho mob yuav tshem cov cuab yeej siv hla koj lub plab mus kuaj seb koj lub tsev menyuam, tus me nyuam, thiab tus me nyuam nyob qhov twg.
  • Koj tus kws kho mob yuav khaws cov hlwb ntawm cov hnoos qeev nyob rau hauv ib ntawm ob txoj kev: los ntawm koj lub ncauj tsev menyuam nrog txoj hlab nyias hu ua lub raj xa dej, lossis siv rab koob ntawm koj lub plab.

CVS ib txwm ua nyob nruab nrab ntawm lub lim tiam 10 thiab 13 ntawm cev xeeb tub.

Pob Txha Los Ntawm Cov Mob Hlwb thiab Txia. Yog tias koj raug mus sim lossis kho qee yam mob cancer lossis ntshav tsis meej, koj tus kws khomob yuav tsum coj cov pob txha mus kho kom zoo. Rau qhov ntsuas no:

  • Koj yuav tau pw ntawm koj sab lossis koj lub plab, nyob ntawm seb cov pob txha twg yuav siv rau kev kuaj. Kev ntsuam xyuas mob pob txha feem ntau yog coj los ntawm lub pob txha txha.
  • Lub vev xaib yuav muab ntxuav nrog kev siv tshuaj tua kab mob.
  • Koj yuav tau txais kev txhaj tshuaj ntawm cov lej daws.
  • Thaum uas thaj chaw loog, lub tsev kho mob mam li coj tus qauv.
  • Rau cov pob txha ua pob txha tawm, uas feem ntau ua tiav ua ntej, cov kws kho mob yuav ntxig ib rab koob ntawm cov pob txha thiab rub tawm cov hlwb pob txha tawm thiab ua hlwb. Tej zaum koj yuav hnov ​​ib qho mob siab heev tab sis qhov mob luv thaum lub koob tau ntxig.
  • Txog kev tshem tawm cov pob txha ntawm cov pob txha, cov kws kho mob yuav siv cov cuab yeej tshwj xeeb uas ntswj rau hauv cov pob txha kom coj tawm cov qauv ntawm cov pob txha ua pob txha. Koj tuaj yeem hnov ​​qee qhov kev nyuab siab rau lub xaib thaum lub sijhawm coj mus kuaj.

Kuv puas yuav tau ua ib yam dab tsi txhawm rau npaj rau qhov kev xeem?

Koj tsis tas yuav muaj kev npaj tshwj xeeb rau kev kuaj cov karyotype.

Puas muaj kev pheej hmoo rau kev kuaj?

Txoj kev kuaj ntshav muaj feem me me. Koj yuav muaj mob me lossis doog ntshav ntawm qhov chaw tso rab koob, tab sis feem ntau cov tsos mob ploj mus sai.

Kev kuaj mob Amniocentesis thiab CVS feem ntau yog cov txheej txheem muaj kev nyab xeeb heev, tab sis lawv muaj kev pheej hmoo me me uas ua rau nchuav menyuam. Tham nrog koj tus kws kho mob txog cov kev pheej hmoo thiab txiaj ntsig ntawm cov kev kuaj no.

Tom qab cov pob txha mob pob txha thiab cov kev kuaj me me, koj tuaj yeem hnov ​​txhav txhaus lossis mob ntawm qhov chaw txhaj tshuaj. Qhov no feem ntau yuav ploj mus nyob hauv ob peb hnub. Koj tus kws kho mob yuav hais kom noj tshuaj los yog sau tshuaj kom pab daws qhov mob kom zoo.

Cov txiaj ntsig li cas?

Yog tias koj cov txiaj ntsig tau tsis meej (tsis yog li ib txwm,) nws txhais tau tias koj lossis koj tus menyuam muaj ntau dua lossis tsawg dua 46 chromosomes, lossis nws muaj qee yam tsis meej txog qhov loj me, cov duab, lossis cov qauv ntawm ib lossis ntau ntawm koj lub chromosomes. Kev siv lub tshuab hluav taws xob tsis zoo tuaj yeem ua rau ntau yam muaj mob. Cov tsos mob thiab mob hnyav nyob ntawm seb cov chromosomes tau cuam tshuam li cas.

Qee qhov teeb meem uas tshwm sim los ntawm chromosomal tsis xws luag muaj xws li:

  • Mob ntsws qis, kev cuam tshuam uas ua rau kev xiam oob khab thiab kev loj hlob qeeb
  • Edwards syndrome, kev tsis sib haum xeeb uas ua rau muaj teeb meem hnyav hauv lub plawv, lub ntsws thiab lub raum
  • Turner mob, kev tsis sib haum xeeb hauv cov menyuam ntxhais uas cuam tshuam kev loj hlob ntawm tus yam ntxwv poj niam

Yog tias koj tau kuaj vim tias koj muaj qee yam mob qog noj ntshav lossis ntshav tsis txaus, koj cov txiaj ntsig tuaj yeem qhia tau seb koj tus mob puas yog mob los ntawm kev xeb xoos ib ce. Cov txiaj ntsig no tuaj yeem pab koj tus kws kho mob npaj qhov kev kho mob zoo tshaj plaws rau koj.

Kawm paub ntau ntxiv txog cov kev sim hauv chaw soj ntsuam, cov chaw siv ntsuas, thiab nkag siab cov txiaj ntsig tau.

Puas muaj lwm yam ntxiv Kuv xav paub txog kev sim ntsuas karyotype?

Yog tias koj tab tom xav txog kev sim lossis tau txais cov txiaj ntsig tsis zoo ntawm koj kev kuaj ntsuas karyotype, nws yuav pab hais lus rau tus kws sab laj tswv yim caj ces.Tus kws pab tswv yim txog caj ces yog tus kws tshaj lij kawm tiav los ntawm kev tshawb fawb caj ces thiab kev tshuaj ntsuam caj ces. Nws tuaj yeem piav qhia koj qhov txiaj ntsig tau li cas, qhia koj kom txhawb nqa cov kev pabcuam, thiab pab koj txiav txim siab txog koj kev noj qab haus huv lossis koj tus menyuam kev noj qab haus huv.
