Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: PWS yana haifar da wani abu na epigenetic da aka sani da imprinting, wanda ya haifar da sharewar kwafin mahaifin SNRPN da NDN necdin genes tare da tarin snoRNAs: SNORD64, SNORD107, SNORD108 da kwafi biyu na SNORD109, kwafi 29 na SNORD116 (HBII-85) da kwafi 48 na SNORD115 (HBII-52). Waɗannan suna kan chromosome 15 da ke yankin 15q11-13. Wannan yankin da ake kira PWS / AS na iya ɓacewa ta ɗayan hanyoyin da yawa na kwayoyin halitta, wanda a mafi yawan lokuta yakan faru ne ta hanyar maye gurbi na bazata. Sauran, ƙananan hanyoyin da suka hada da uniparental disomy, maye gurbi na yau da kullun, canzawar chromosome, da sharewar kwayar halitta. Saboda bugawar, kwafin da aka gada na mahaifa na waɗannan kwayoyin halittar kusan shiru ne, kuma kawai kwafin mahaifa na kwayoyin halittar suna bayyana. PWS sakamakon asarar kwafin mahaifin wannan yankin. Cire wannan yanki a kan chromosome na mahaifa yana haifar da cutar Angelman (AS). PWS da AS suna wakiltar lokuta na farko da aka ruwaito na cututtukan cututtuka a cikin mutane.  Tambaya: Menene yake haddasa PWS?
