Ukuluka iminwe noma izinzwane

Ukubamba iminwe noma izinzwane kubizwa ngokuthi yi-syndactyly. Kusho ukuxhumana kweminwe emi-2 noma ngaphezulu noma izinzwane. Isikhathi esiningi, izindawo zixhunywe ngesikhumba kuphela. Ezimweni ezingavamile, amathambo angahlangana ndawonye.

I-Syndactyly ivame ukutholakala ngesikhathi sokuhlolwa kwezempilo kwengane. Ngendlela evame kakhulu, i-webbing yenzeka phakathi kwezinzwane zesibili nezesithathu. Leli fomu livame ukuzuzwa njengefa futhi alijwayelekile. I-Syndactyly nayo ingenzeka kanye nezinye izinkinga zokuzalwa ezibandakanya ugebhezi, ubuso namathambo.

Ukuxhumeka kwewebhu kuvame ukukhuphukela ekuhlanganeni kokuqala komunwe noma uzwane. Noma kunjalo, bangakwazi ukugijima ubude bomunwe noma uzwane.

"I-Polysyndactyly" ichaza zombili izindwangu kanye nokuba khona kwenani elengeziwe leminwe noma izinzwane.

Izimbangela ezivamile zifaka:

• I-Down syndrome
• Ifa syndactyly

Izimbangela ezingavamile kakhulu zifaka:

• I-Apert syndrome
• I-Carpenter syndrome
• Isifo seCornelia de Lange
• I-Pfeiffer syndrome
• Isifo sikaSmith-Lemli-Opitz
• Ukusetshenziswa komuthi i-hydantoin ngesikhathi sokukhulelwa (umphumela we-fetal hydantoin effect)

Lesi simo sivame ukutholwa lapho kuzalwa lapho ingane isesibhedlela.

Umhlinzeki wezokunakekelwa kwempilo uzokwenza ukuhlolwa ngokomzimba abuze ngomlando wezempilo wengane. Imibuzo ingafaka:

• Yimiphi iminwe (izinzwane) ethintekayo?
• Ngabe kukhona amanye amalungu omndeni abenenkinga?
• Yiziphi ezinye izimpawu noma ukungajwayelekile okukhona?

Usana olune-webbing lungaba nezinye izimpawu zokuthi ngokuhlangana kube yizimpawu zesifo esisodwa noma isimo. Leso simo sitholakala ngokuya ngomlando womndeni, umlando wezokwelapha, nokuhlolwa komzimba.

Ukuhlolwa okulandelayo kungenziwa:

• Izifundo ze-Chromosome
• Ukuhlolwa kwelebhu ukuhlola amaprotheni athile (ama-enzyme) nezinkinga ze-metabolic
• Ama-X-ray

Ukuhlinzwa kungenziwa ukuhlukanisa iminwe noma izinzwane.
