Cov microfibrils no muab lub zog txhawb nqa cov txheej txheem txhawb nqa hauv cov ntaub so ntswg thiab tsis sib txuas thoob plaws lub cev.

Cov lus nug tseem yog, qhov haujlwm ntawm fibrillin 1 yog dab tsi?

Li qub Muaj nuj nqi FBN1 noob muab cov lus qhia rau ua cov protein loj hu ua fibrillin - 1 .
