Mng'alu umodzi wamanja

Chingwe chimodzi cha kanjedza ndi mzere umodzi womwe umadutsa chikhato cha dzanja. Anthu nthawi zambiri amakhala ndi zotupa zitatu m'manja mwawo.

Kachilomboka nthawi zambiri kamatchedwa kachipale ka kanjedza kamodzi. Liwu lakale loti "simian crease" siligwiritsidwanso ntchito, chifukwa limakhala ndi tanthauzo loipa (Mawu oti "simian" amatanthauza nyani kapena nyani).

Mizere yosiyanitsa yomwe imapanga zikuluzikulu imawoneka m'manja mwake ndi pansi pamapazi. Mgwalangwa uli ndi zokongoletsera zitatu nthawi zambiri. Koma nthawi zina, zolembazo zimalumikizana kuti zikhale chimodzi.

Zilimba za Palmar zimakula mwana akamakula m'mimba, nthawi zambiri kumapeto kwa sabata la 12 la bere.

Mtengo umodzi wa kanjedza umapezeka mwa anthu pafupifupi 1 mwa 30. Amuna amakhala ochulukirapo kuwirikiza kawiri kuposa akazi kukhala ndi vutoli. Mitengo ina ya kanjedza imatha kuwonetsa zovuta ndi chitukuko komanso yolumikizidwa ndi zovuta zina.

Kukhala ndi kachipangizo kakang'ono ka kanjedza nthawi zambiri kumakhala kwachilendo. Komabe, amathanso kuphatikizidwa ndi mikhalidwe yosiyanasiyana yomwe imakhudza kukula kwamunthu kwamunthu ndi thupi, kuphatikiza:

• Matenda a Down
• Matenda a Aarskog
• Matenda a Cohen
• Matenda a fetal alcohol
• Trisomy 13
• Matenda a Rubella
• Matenda a Turner
• Matenda a Klinefelter
• Pseudohypoparathyroidism
• Cri du chat matenda

Khanda lomwe lili ndi kanjedza kamodzi likhoza kukhala ndi zizindikilo ndi zizindikilo zomwe, zikagwirizanitsidwa pamodzi, zimafotokozera matenda kapena vuto linalake. Kuzindikira kwa vutoli kumadalira mbiri ya banja, mbiri yazachipatala, ndikuwunika kwathunthu.

Wothandizira zaumoyo wanu akhoza kufunsa mafunso monga:

• Kodi pali mbiri yabanja ya Down syndrome kapena matenda ena omwe amadza chifukwa chokhwima kamodzi?
• Kodi pali wina aliyense m'banjamo amene ali ndi kachidutswa kamodzi kadzanja kakang'ono popanda zisonyezo zina?
• Kodi mayi amamwa mowa ali ndi pakati?
• Ndi zisonyezo zina ziti zomwe zilipo?

Kutengera mayankho a mafunso awa, mbiri yazachipatala, ndi zotsatira za kuyezetsa thupi, kuyesa kwina kungakhale kofunikira.
