Keu chromosome i loko o kānaka. chromosomal abnormalities

Ke kanaka kino - o ka luna 'multidimensional kahua, a hana ma kekahi mau pae. I nā loko, a aeee ke hana i ka manawa pono, i ka hana i ho'ākāka 'biochemical keʻano o ka hanaʻana pono pū i kekahi mau waiwai. Kēia pono o ka paa hookumu ana, i mea, i ka pololei EYI o ka aaiaoe kivila. He hoʻomaopop 'ana i aaiaoe mea hoʻi i ke kūpono' ana o ke embryo.

Naʻe, i ka 'ike hou aaiaoe i kekahi manawa i hoʻomaka ai iʻikeʻia i loko o nui ahahui a hai aku i kanaka nā'ōewe. Na hewa i kapaʻia mutations o nā'ōewe. Ma kekahi hihia, keia pilikia ua pili i ka mall huahelu o ka keena, i mea e okoa chromosomes. Alaila, ma keia hihia, ua kapaʻia ka hewa chromosome mutation.

Kēlā me kēia kanaka aeea maʻamau a iloko ona i kakauia na ia helu ana o chromosomes. Ka mea, i hui pu ia e ka ia nā'ōewe. I ka piha 'ia paha o 23 hui o chromosomes, akā, e emi ma mua o 2 manawa i loko o ka germ keena. O ke kumu ho i ka mea e ma fertilization kuʻi nukeliu o sperm a me ka hua keena e ho i ka piha pu ana o nā mea a pau i ka mea e pono ai nā'ōewe. Lākou puʻunaue 'Aʻole i hoʻomaka ai randomly, a ma ka pololei i kekahi mea, me ka laina kaʻina, Ua like me ka ia no nā kanaka.

Chromosomal mutations he hoʻonui i ka loli i loko o lākou ka helu a me ka 'ole. Pela, aole paha e keu chromosome paha, conversely, ka mea, e ikeia kou nalo ana. Kēia imbalance hiki i abortion paha he hoʻonui i ka helehelena o ka chromosomal kāna hana.

Ano o chromosomes a me kā lākou mau abnormalities

Chromosome - he lawe o aaiaoe 'ike i loko o ka halepaahao. Ua ho palua ka DNA lātoma ma ka eiiieaena me histones. Ho okumu i wahi ma ka prophase chromosomes (no ka aeea mahele manawa). Naʻe, i ka metaphase ia maʻalahi e hoʻopaʻa haʻawina. Chromosomes i haku o nā chromatids i ua pili iniiaiie constriction aia ma ka halepaahao equator. Helu constriction i hookaawale chromosome 2 hoohalua ana i ka ia a me kekahi mau ia i kona loa.

ʻO kēia mau 'ano o nā chromosomes:

• metacentric - a me na mea kaua o ka like loa;
• submetacentric - a me na mea kaua o ke kaiʻewaʻewa lōʻihi;
• acrocentric (koʻokoʻo) - kekahi pōkole, a me ka 'ē aʻe poohiwi lōʻihi.

Anomalies i kŘpa a nui a me ka meaʻuʻuku. Research epekema oko ma ka okoʻa no ka manawa. Kekahi ia akulla 'me ka microscope mea,ʻaʻole hiki. Ma ia ano hihia, e hoʻohana i ka palena pau i hookohu aku i iaoia, akā, wale i ka wa a ka iʻa hapa he pōpilikia ma ka miliona o nucleotides. Wale ma e kukulu i ka nucleotide kaʻina hiki huai ae liʻiliʻi mutations. A nui aʻe 'ana ka hopena o ka hai ia ma luna o ke kanaka kino.

I ka wa e kaawale aku o kekahi chromosome abnormality kapa monosomy. Keu chromosome i loko o ke kino - trisomy.

chromosomal maʻi

Chromosomal maʻi - aaiaoe maʻi e hana ana i ka hopena o ka chromosomal abnormality. Ka mea, e kū aʻeʻoe ma muli o ka loli ma ka helu o nā chromosomes a nui rearrangements

I ka wā o ka lapaau ua no mamao mai ka papa kiʻekiʻe o? Acaeoey, ka mea i manaoio aku i kekahi kanaka i 48 chromosomes. Ua ua wale i ka makahiki 1956 ka mea, e hoʻokele i ka pono hoʻomaulia kēia heluna o, a kuhikuhi i ka pilina ma waena o ka naha o ka helu ana o chromosomes a me kekahi hereditary maʻi.

3 makahiki ma hope, i ka Palani nä känaka 'epekema J. Lejeune, ka mea i loaʻa i ka' aʻe 'ana o na kanaka o ka noʻonoʻo' ana a me ka ia'ku i ka maʻiʻaʻai ua pololei e pili ana i ka genomic mutation. Ua ua no ka keu chromosome 21. I mea kekahi o ka mea uuku, akā, ka mea, ua i kia he nui helu o nā'ōewe. Keu chromosome Ua malama i ka 1 mai o 1,000 nā pēpē. Kēia chromosomal maʻi mea ma kahi loihi ka loa? Anoee, a ike me Down maʻi pale.

Ma ka ia 1959 ka mea i aʻo a ua maopopo i ke alo o ke kane keu X chromosome hiki aku ai i Klinefelter ka maʻi i loko o a ke kanaka poino, mai noʻonoʻo retardation a me ka infertility.

Naʻe, hoʻowahāwahā i ka mea i ka malama, a aʻo no ka lōʻihi manawa chromosomal abnormalities, i ke kālā no lapaʻau mea,ʻaʻole hiki ke hana aaiaoe maʻi. Akā, e aho modernized ki ina hana like o kaʻike, e like mutations.

Kumu o ka keu chromosome

Ke anomaly Ua ka wale kumu no ka muli o chromosome 47 kahi o ka 46. akamai i loko o ka mahinaʻai o ke lapaau i ua maopopo i ka iniiaiie kumu o ka keu chromosome - i ka makahiki o ka expectant makuwahine. Ka mua i ka hapai, ka mea i oi aku ka likelihood o nondisjunction. Pono no keia kumu, e ao aku i na wahine i hanau i ka 35 makahiki. I Ina o ka hāpai keiki ma hope o ka hoouka kaua ana o keia makahiki, e kekahi mea loiloi.

Nā kumumea e hoʻonui ai i ka muli o ka keu chromosome, loaʻa i ka nui o anomalies mahuahua i loko o ke ao nei a pau, ke degere o? Aneie haumia ea, a oi.

Ua Ua manaoio aku i ke keu chromosome ia lŘlŘ ina oe e noho ana i loko o ke ano like hihia. O pono i nā kaʻao: haʻawina Ua hōʻike i nā mākua o kona mau keiki e ae mai ka chromosomal maʻi i pono ola karyotype.

ʻike, a kipa i ke keiki me ka chromosomal abnormality

Kuokoa ana o ka 'aʻe' ana o nā chromosomes, i kapaia o aneuploidy loiloi, e hōʻike ana i ka embryo deficiency a loaʻa pākeu o chromosomes. Hapai wahine mua ma mua o 35 makahiki e undergo i ke kaʻina hana o ka loaa ana i ka hāpana o amniotic loli. Inā ua loaʻa he 'aʻe' ana o ka karyotype, ka expectant makuahine, e pono e 'ōlelo i ka hāpai keiki, e like me ke keiki i hanau, e ae aku i ke ola a pau i ka maʻi nui i ole ka hoʻokō lapaau.

'Aʻe' chromosomes nui mai i ka maternal ka molekumu o,ʻaʻole naʻe e nana ole wale fetal keena, akā, i waiwai i mea i hanaʻia i ke oo ana. Kēia kaʻina hana ua kapaʻia kaʻike, a aaiaoe kāna hana o ka Polar kino.

Down ka maʻi pale

Epekema i ho'ākāka 'ia mua Mongolism mea Down. Keu chromosome, i ka maʻi i loko o nā'ōewe ke alo o ka i ua koi 'ia e ulu, ua, ua aʻo nui. A lohe o Mongolism ia lŘlŘ ma chromosome 21 trisomy. Ia mea he maʻi kanaka kahi o ka 46 huli 47 chromosomes. Na ka papa kuhikuhiE hiʻona - ka lag ma ka ulu ana.

Keiki ka mea i ke alo o ka keu chromosome ua malamaia,ʻike piʻi hihia nui ke aʻo 'ana i nā puke ma nā kula, no laila, e pono i kekahi koho iaoia o ka hoʻonaʻauao. Ma waho aʻeo ia ka noʻonoʻo, he mea he haiahū kūmau, a me physical? Acaeoey, oia hoi: nō naʻe o nā maka, i lalo ka maka, he akea lehelehe, olelo i lalo, hoopokole ole ia mai lala a me nā wāwae, he nui loa o ka ili, i loko o ka'ā'ī wahi. Life expectancy ma awelika o 50 makahiki.

Patau maʻi pale

Ua i pili trisomy Patau maʻi pale, ma a he mea ekolu kope o ka chromosome 13. A kiʻiona hiʻona o ka hoʻohuikau o ka Central ko mākou hopohopo'ōnaehana a me kona underdevelopment. mau malformations, a me nā mea maʻi hiki i malama congenital maʻi o ka naau. More ma mua o 90% o nā poʻe me ka maʻi pale o Patau make i loko o ka makahiki mua o ke ola.

Edwards maʻi pale

Kēia anomaly, e like mua kamalii, pili i ka trisomy. Ma keia hihia mākou e kamaʻilio e pili ana i ka 18th chromosome. Edwards maʻi pale ua wehewehe aku e likeʻole kāna hana. Holo nōhie, e hoomanawanui i hōʻike iwi deformation, i ka wehewehe ana oia i ke kinona o ka puniu wale no, pilikia a me ka ÷ naehana hanu a me ka mea'ōnaehana mānowai koko kahua. Life expectancy mea IeAUPIIe, IAa IO ma kahi o 3 mahina, akā, kekahi keiki ola mahope mai a hiki i ka makahiki.

Endocrine maʻi me ka chromosomal abnormalities

Ma waho aʻeo ia mau syndromes, chromosomal abnormalities, loaʻa nō kekahi ma a he mea no hoi i ka laulā a me ka mall anomaly. Na maʻi nā:

1. Triploids - he ke nānā chromosome kāna hana i loko o lākou a modal helu, he 69. hāpai keiki ana welau a kakahiaka miscarriage, akā, ke ola o ke keiki, aole ia e ola oi aku mamua o 5 mahina, he nui na hanau mā.
2. Wolf-Hirschhorn maʻi pale - Ua hoi kekahi o ka mea pohihihi keia chromosomal abnormalities, a hoʻomōhala ana i aie ai i ka moʻolelo holoi ana o ka distal hope o ka pōkole lima o ka chromosome. A pilikia 'āpana o keia kāna hana he 16,3 ma chromosome 4p. Typical symptoms - pilikia i loko o ka ulu, ulu retardation, ke kāʻili 'ana, a me ka typical lehalehu t hiʻona
3. Prader-Willi maʻi pale - ka maʻi ka loa pohihihi keia. I ka ua anomalous chromosome 7 nā'ōewe a me na hapa o ka 15 paternal chromosome 'aʻole i hana, a holoiʻia. Tags: scoliosis, strabismus, lohi physical a me ka 'imi naʻauao? Acaeoey, luhi.

Pehea e ho'āla i ke keiki me ka chromosomal kāna hana?

E hoʻokū i kekahi keiki me congenital chromosomal maʻi mea e maʻalahi. I mea e e kou ola uuku, i kekahi mau rula pono e hahai. Mua, ka mea e e koke lanakila o ka manao a me ka makau. ʻO ka lua, eʻaʻole pono e kali ka wā hulina, no ka mea culprit, e hakuʻole. Ke kolu, ka mea, mea pono e hooholo ia ma ke ano o ke kōkua koi 'ia i ke keiki a me ka ohana, a laila e huli i ka hoʻomalu no ka' inikua, manaʻoʻike a me ka hoʻonaʻauao kōkua.

I ka makahiki mua o ke olaʻike, ka loa nui, e like me ka papa Hawaii e hoʻomohala i loko o kēia wā. Me ke kōkua o nā 'Oihana ma ke keiki koke kuai Hawaii mākau. He mea pono e objectively ninaninau i ke kamaiki ma ka pathology o ka maka a me ka hālāwai hoʻolohe manaʻo. Nō hoʻi, E ke ike ma ka pediatrician, endocrinologist a me neuropsychiatrist i ke keiki.

Na makua i hooluoluia mai ai e komo i loko o ka hana 'ē aʻe no ka loaa waiwai he mea hiki aʻo mai kanaka, ka poe i lanakila keia kulana, a ua makaukau e kaʻana.

Media keu chromosome nui aloha, e ka mea oluolu i hoala, aʻo ia e like me kona pono, e loaa i ka apono o ka makua. I ka nui o ka? Acaeoey o kūikawā keiki, e hilinaʻi ma luna o pilikia loa ia, e lilo ia i ao aku kumu o Hawaiʻi. Maʻi keiki, naʻe lagging ma ke kua o na mea e ae, aka, e noi aku i ka puu o ka noonoo. He manawa pono e paipai i ke keiki ka kuokoa. Pakiko i aʻo pehea e ia ma ke kumu hoʻohālike, a laila, i ka hopena e ole kali lōʻihi.

Children me ka chromosomal kāna hana i kuʻu mai me ka kūikawā talena i ua hōʻike. Ua hiki e mele haʻawina a me ka unuhi. He nui e hoʻoikaika i kou bebe, hulaʻeleu pāʻani a me ka ulu Hawaii mākau, ka heluhelu, a me ka maʻa i ka? Eia a me ka pololei. Inā i ke keiki, e hōʻike aku i koʻu aloha, malama, maliu a me ka aloha,ʻo ia, e pane ana ma keia ano.

Ua loaʻa ke hoolaia?

I ka lā, i ka maʻi hiki ole ke hoola chromosome; Kēlā me kēia i manaoia hana mea mana, akā, me ko lakou lapaʻau hopenaʻoi loa i ole, ua hoao aku au ia. E holomua i loko o ka ulu ana o ka socialization a me ka 'āpana o ka mākau kōkua kahua hoʻonohonohoʻana' inikua a me ka hoʻonaʻauao kōkua.

pono i na manawa a pau e ike ia ka maʻi keiki ma ka hoʻomalu i lapaau i hele mai ai i ke kiʻekiʻe ma i mea hiki ia i ka mea e pono ai lako a pan a me ka acee? iuo oeiia o Inc. Kumu i pili laekahi hoʻokokoke mai ma o ke aʻo a me ka hoʻopulapulaʻana o ke keiki.
