Ku wa kabiri, abashakashatsi bavuze ko gupima amaraso byoroshye bishobora kumenya igitsina cy'inda mu byumweru cumi na bibiri bya mbere byo gutwita.

Ibyavuye mu bushakashatsi bwakozwe n'abashakashatsi bo muri Koreya y'Epfo bishobora gutuma habaho ikizamini kidashobora gutuma ababyeyi vuba aha bamenya igitsina cy'umwana wabo hakiri igihembwe cya mbere kandi ibizamini nk'ibi bikaba ari byo byambere bibaye. Kuri Itangazo.

Abashakashatsi basanze ibipimo byinshi bya enzymes ebyiri (DYS14 / GAPDH) bivanwa mumaraso yumugore utwite byerekanaga niba umwana azaba umuhungu cyangwa umukobwa.

Kugena igitsina hakiri kare birahari, icyakora bigakorwa muburyo butera nka chorionic villus sampling cyangwa amniocentesis, byombi bisaba icyitegererezo cyimyanya myibarukiro cyangwa amazi ava mumasaho amniotic. Inzira ziriho nazo zitwara kimwe kugeza kuri bibiri ku ijana byo gukuramo inda, kandi muri rusange ntibishobora gukorwa kugeza ibyumweru 11 byo gutwita.

Ikindi cyemezo cyizewe kidahwitse cyuburinganire bwuruhinja ukoresheje ultrasonography ntigishobora gukorwa mugihembwe cya mbere kuko iterambere ryuruhinja rwimyanya ndangagitsina yo hanze ntiruzura, ikindi kandi ibisubizo byubu birerekana ko uburyo bushya bushobora kugabanya ibikenewe muburyo butemewe kubagore batwite bitwaje. abashakashatsi bavuze ko X ihuza chromosomal idasanzwe nubufasha mugusobanura ibyasomwe na ultrasound.

Hyun Mee Ryu, umushakashatsi wo mu ishami ry’ububyaza n’umugore mu bitaro bikuru bya Cheil n’ikigo nderabuzima cy’abagore ku ishuri ry’ubuvuzi rya KwanDong i Seoul yavuze ko we n’itsinda rye bakusanyije plasma y’ababyeyi ku bagore 203 mu gihembwe cya mbere cyo gutwita no yahanuye ADN yibyara mugupima methylation yihariye ya polymerase reaction ya U-PDE9A.

Nyuma yaho, reaction ya multiplex polymerase yakoreshejwe mukugereranya icyarimwe ingano ya DYS14 na GAPDH mumaraso yababyeyi, ibisubizo byaje kwemezwa na phenotype akivuka.

Umuyobozi mukuru w'ikinyamakuru Gerald Weissmann yagize ati: "Nubwo imirimo myinshi igomba gukorwa mbere yuko ikizamini nk'iki kiboneka henshi, iyi nyandiko irerekana ko bishoboka guhanura igitsina cy'umwana hakiri ibyumweru bike nyuma yo gusama". Ikinyamakuru FASEB, ikinyamakuru ubushakashatsi bwashyizwemo, mu itangazo.

Weissmann yongeyeho ati: "Kugeza ubu, ababyeyi rimwe na rimwe bahabwa amakuru atari yo yerekeye igitsina cy'umwana wabo utaravuka; iki kizamini kigomba gufasha mu gukemura amakimbirane ayo ari yo yose yakozwe muri iki gihe."
