Prader-Willi syndrome yog suav tias yog ib yam kab mob uas tsis tshua muaj caj ces nyob rau hauv uas xya lub noob nyob rau ntawm 15th leej txiv chromosome yog tag nrho lossis ib nrab tsis tuaj thiab tsis ua haujlwm li qub.

Cov kab mob genetic no tshwm sim vim qhov tseeb tias tsuas yog cov ntawv luam ntawm qee cov noob tau txais los ntawm leej txiv ua haujlwm raug. Kuj tseem muaj qee qhov tsis sib xws ntawm cov ntawv luam ntawm leej niam. Cia peb saib ntxiv.

Hauv lub cev ntawm tus neeg noj qab haus huv muaj cov ntawv theej ntawm cov noob, ua tsaug rau lub cev tuaj yeem ua haujlwm yam tsis muaj kev sib txawv ntawm cov qauv. Nrog rau kev txhim kho ntawm Prader-Willi syndrome, cov ntawv luam no tsis tuaj. Tam sim no muaj cov kab mob paub tias zoo ib yam li tus kab mob no.

Ib qho zoo sib xws ntawm qhov tshwm sim kuj tuaj yeem pom hauv Angelman syndrome, tab sis txawm tias qhov no, kev hloov pauv cuam tshuam rau cov khoom siv caj ces tau txais los ntawm leej niam. Cov kab mob zoo li no, raws li txoj cai, tshwm sim rau lawv tus kheej hauv ntau hom thiab muaj qhov sib txawv ntawm qhov hnyav. Tab sis, txawm li cas los xij, lawv kho tsis tau.

Causes of the Syndrome

Prader-Willi Syndrome -hereditary deterministic pathology, uas tsuas yog nrog kev loj hlob ntawm tej yam tsis xws luag. Hauv lwm lo lus, nrog qee yam kab mob chromosomal, niam txiv cov noob pib raug kev txom nyem, uas ua rau muaj kev hloov pauv loj. Daim duab kho mob tsim kho thaum xya lub noob hauv 15 leej txiv tsis tuaj lossis tsis qhia. Tib lub sijhawm, cov ntaub ntawv embedded hauv DNA tsis hloov mus rau RNA.

Cov kws tshawb fawb, uas tau koom nrog hauv kev tshawb nrhiav qhov ua rau ntawm qhov kev hloov pauv ntawm cov kab mob no, yav tas los ntseeg tias vim muaj qhov sib txawv no, homozygote tau tsim. Tom qab ntawd nws tau txiav txim siab tias qhov tseem ceeb tshaj plaws muaj nyob hauv autosomes, thiab txoj hauv kev tseem ceeb ntawm kev sib kis ntawm tus kab mob yog kev qub txeeg qub teg.

Cov noob caj noob ces tau ua ntau yam kev tshuaj ntsuam cytogenetic ntawm cov kab mob, nrog kev pab los ntawm kev pom tias cov txiv ntawm cov menyuam cuam tshuam los ntawm tus kab mob tau hloov pauv ntawm chromosome 15. Cov duab ntawm cov menyuam yaus uas muaj tus mob Prader-Willi tau nthuav tawm hauv peb tsab xov xwm.

Genetic mechanism

Hnub no, nws tau raug tsim los ua qhov tseeb tias nrog cov kab mob no, 15th chromosome raug puas tsuaj hauv ntu ntawm q11.2 txog q13. Tib yam tshwm sim nrog Angelman syndrome. Txawm li cas los xij, tus kab mob no muaj cov tsos mob sib txawv kiag li. Qhov kev tsis sib haum xeeb no tsuas yog piav qhia los ntawm qhov tshwm sim hauv kev tshawb fawb caj ces xws li kev luam tawm genomic, nrog rau kev tsis sib haum xeeb.

Nyob rau hauv kev tsis sib haum xeeb, ob qho tib si chromosomes tau txais los ntawm ib leej niam leej txiv, tab sis rau qhov no tshwm sim, cov khoom siv noob yuav tsum cuam tshuam.qee yam biochemical. Qhov tseeb no tau tsim los siv kev tshuaj xyuas prometaphase thiab DNA cim ntawm qee loci ntawm chromosome.

Prader-Willi Syndrome yog tshwm sim los ntawm ob lub ntsiab mechanisms: ib tug microdeletion ntawm 15th chromosome, tau txais los ntawm leej txiv, thiab idiosomy ntawm leej niam chromosomes, ob leeg tau txais los ntawm leej niam.

Nrog genomic imprinting, phenotype hloov nyob ntawm seb qhov qhia tau tshwm sim ntawm cov chromosomes ntawm leej txiv lossis leej niam.

Mechanisms of disorders uas tshwm sim nyob rau hauv lub cev ntawm tus neeg mob uas muaj ib tug syndrome tseem tsis tau kawm tag nrho. Txawm li cas los xij, tib lub sijhawm lawv muaj ntau cov tsos mob tshwm sim tsuas yog rau hom kab mob no. Nws ntseeg tau tias cov neeg mob nce qhov hnyav vim muaj kev tsim cov rog ntau ntxiv thiab txo qis lipolysis.

Tsis tas li ntawd, muaj kev ua haujlwm tsis zoo ntawm lub hypothalamus, uas feem ntau tau sau tseg hauv nws ob lub nuclei - ventrolateral thiab ventromedial. Cov txheej txheem zoo li no ua rau tsis ua tiav hauv kev tsim cov yam ntxwv ntawm kev sib deev theem nrab. Kev ua haujlwm ntawm tyronase txo qis hauv cov hauv paus plaub hau thiab melanocytes ua rau cov plaub hau, tawv nqaij, thiab iris hypopigmentation.
