Dzimwe nguva chiremba anogona kukuudza kuti pane shanduko diki mumajini ako, inonzi 'Robertsonian Translocation'. Ungatya paunonzwa mashoko aya. Zvakajairika kufunga zvinhu zvakaita sekuti, 'Ichi chirwere chakakomba here? Chichava dambudziko kuvana vangu here?' Asi usatya. Ichi chinhu chisingazivikanwe nevanhu vazhinji, asi chakakosha kuziva. Ichi chirwere chisingawanzoitiki, zvichireva kuti paavhareji, munhu mumwe chete pavanhu 900 ndiye anogona kuva nacho. Nhasi, tichataura nezvazvo nenzira iri nyore, nenzira yaunogona kunzwisisa.
Zvichitaurwa zviri nyore, majini nemakromosomu chii?
Tisati tanzwisisa izvi, ngatitarisei kuti miviri yedu yakagadzirwa sei. Fungidzira kuti miviri yedu iraibhurari ine sherufu hombe yemabhuku. Bhuku rega rega riri muraibhurari iyi rine mirairo yakatigadzira.
Mabhuku aya ndiwo atinodaidza kuti machromosomes mukurapa. Aya ndiwo anochengeta ruzivo rwese rwemajini edu - seti yemirairo inosarudza zvese kubva paruvara rwebvudzi redu, ruvara rwemaziso, kureba, uye ruvara rweganda.
Kazhinji, munhu ane hutano hwakanaka ane machromosomes 46. Paaya, tinowana 23 kubva kuna amai vedu uye mamwe 23 kubva kuna baba vedu.
Saka kutamiswa uku kweRobertsonian kunoitika sei?
Pama chromosomes makumi mana nematanhatu ari mumuviri wedu, ma chromosomes 13, 14, 15, 21, uye 22 akakosha zvishoma. Anonzi ma chromosomes acrocentric . Ma chromosomes aya ane 'ruoko' rumwe rupfupi zvikuru. Chinonyanya kukosha ndechekuti ruoko rupfupi urwu haruna ruzivo rwemajini rwakakosha pakushanda kwemuviri wedu.
Zvino, muRobertsonian Translocation, chinoitika ndechekuti maoko mapfupi emachromosome maviri pamashanu acrocentric andambotaura anotyoka, uye maoko marefu emachromosome maviri iwayo anonamatirana. Zvakafanana nekutyora zvidimbu zviviri zvidiki zvematanda maviri wozvibvisa, wobva wanamatira zvidimbu zviviri zvikuru zvasara. Ipapo maoko maviri madiki iwayo asingabatsiri anonyangarika.
Kana machromosome maviri akabatana nenzira iyi, huwandu hwemachromosome emunhu hwava makumi mana nemashanu, kwete makumi mana nematanhatu. Asi haazove nematambudziko ehutano. Nekuti zvidimbu zvidiki zvishoma chete zvisina majini akakosha zvakarasika.
Kune mhando dzeizvi here?
Ehe, mamiriro ezvinhu aya anogona kukamurwa kuita mhando mbiri huru. Uchanzwisisa zviri nyore nekutarisa tafura iyi.
| Rudzi | Tsananguro |
|---|---|
| Kutamiswa kweRobertsonian kwakaringana (Kwakaringana) | Vanhu vane chirwere ichi havana zviratidzo kana matambudziko ehutano. Vanorarama hupenyu hurefu uye hune hutano. Kazhinji, havatombozivi kuti vanacho. Vanhu ava vanonzi 'vanotakura' nekuti havana chirwere ichi, asi vanogona kuchipfuudza kuvana vavo. |
| Kutamiswa kweRobertsonian Kusina Kuenzana (Kusina Kuenzana) | Apa ndipo panogona kumuka matambudziko. Apa ndipo panowana majini akawanda kana mashoma. Izvi zvinowanzoonekwa mushure mekuzvarwa kwemwana. Dzimwe nguva, kunyangwe machromosome evabereki ari akajairwa, mamiriro acho anogona kukura mwana achiri kukura mudumbu. Kashoma, mumwe wevabereki ndiye anotakurwa uye mwana anogona kukura nechirwere ichi. |
Mwana anowana sei chirwere ichi nhaka?
Kana munhu anotakurwa neRobertsonian Translocation aine mwana nemumwe munhu, jini racho rinogona kugarwa nhaka nenzira nhatu huru. Fungidzira kuti ndiwe unoritakurwa.
1. Mwana ane hutano hwakakwana: Mwana wako anogona kugara nhaka yemachromosomes akajairwa kubva kwauri nemudiwa wako. Ipapo mwana haazove nematambudziko emajini. Achava neutano hwakakwana.
2. Mwana wacho achavawo mutakuri: Mwana, sewe, anogona kugara nhaka chromosome yakachinjika uye ma chromosome akajairwa. Ipapo mwana haazove nematambudziko ehutano. Asi iye achavawo mutakuri sewe mune ramangwana.
3. Kusagadzikana: Apa ndipo apo mwana anowana huwandu hwakawanda kana hushoma hwezvinhu zvemajini. Semuenzaniso, mwana anogona kugamuchira chromosome yakajairika pamwe chete nechromosome yakawedzerwa. Izvi zvinogona kukonzera mwana kuva nezvimwe zvirwere zvemajini, zvakaita se translocation Down syndrome kana Patau syndrome . Zvisinei, hunhu uye kuoma kwechirwere zvinoenderana nema chromosome chaiwo anogamuchirwa.
Pane dzimwe njodzi here?
Mukadzi ane chirwere cheRobertsonian translocation anogona kunge aine mukana wekubvisa pamuviri wakakwira zvishoma pane wakajairika. Uyewo, vamwe varume vane chirwere ichi vanogona kusangana nedambudziko rehuwandu hwembeu kana kushaya simba rekugadzira mbeu.
Ungaziva sei chirwere ichi?
Vanhu vazhinji havazivi kuti vane chirwere ichi. Vanongoziva chete kana vakambobvisa pamuviri kakawanda kana kuti mwana akazvarwa aine chirwere ichi. Chiremba anozoraira kuti vaongororwe kuti vaone kana chirwere ichi chakaitika.
Kuongororwa kweropa kuri nyore kwazvo. Kuongororwa kweropa kuri nyore. Ropa diki rinotorwa kubva kwauri uye machromosome ari mumasero eropa anoongororwa nemaikorosikopu. Kuongororwa uku kunonzi Karyotyping . Zvinogona kuonekwa zvakajeka kana une machromosome ese makumi mana nematanhatu akatevedzana, kana kuti kana uine rimwe shoma (45), uye kana paine machromosome akabatana.
Kana uchiziva kuti mumwe munhu mumhuri yako ane chirwere ichi chemajini, chiremba wako anogona kukurudzira kuti iwe nemumwe wako muedze kuongororwa uku musati maedza kuva nemwana.
Zvakajairika kuti unzwe kutya uye kunetseka paunonzwa nezvechirwere ichi. Asi chinonyanya kukosha ndechekuwana ruzivo rwakakodzera uye kutsvaga mazano ekurapa anodiwa.
Mharidzo Yekuenda Nayo Kumba
- Kutamiswa kweRobertsonian hachisi chirwere chekutya. Vanhu vazhinji vane chirwere ichi (vanotakura chirwere ichi) vane hutano hwakanaka uye vanorarama hupenyu hwakajairika.
- Dambudziko guru reizvi injodzi yekupa majini kumwana. Zvisinei, kunyangwe uri mutakuri wechirwere ichi, uchiri nemukana wakanaka wekuva nevana vane hutano.
- Kana uine mimba dzinoramba dzichibva, uchinetseka kubata pamuviri, kana kuti une nhoroondo yemhuri yezvirwere zvemajini, kuchenjera kutaura nachiremba wako nezvekuongororwa kwakadai se karyotyping.
- Kana muine mimwe mibvunzo nezvenyaya iyi, musazeza kubvunza chiremba wenyu . Iye achakupai ruzivo rwese, mazano, uye kutumirwa kunorapwa kana zvichidikanwa kuti muwane mazano ezvemajini.
