Funkcija[uredi | uredi izvor]

FAM20A pripada porodici evolucijski konzerviranih lučenih proteina eksprimiranih u mnogim tkivima. Ovaj lokus kodira protein koji se vjerovatno luči i može funkcionirati u hematopoezi.^[7] Mutacija na ovom lokusu povezana je sa bolešću amelogenesis imperfecta i sindromom hiperplazije desni (gingiva). Utvrđene su alternativno prerađene varijante transkripata. [RefSeq, avgust 2011.]

Klinički značaj[uredi | uredi izvor]

Izvješteno je da je mutacija u FAM20A povezana sa amelogenesis imperfecta, nasljednim defektom cakline i sindromom hiperplazija desni.^[8]

Izvješteno je i da mutacije u FAM20A kod ljudi uzrokuju sindrom cakline i bubrega, autosomno recesivni poremećaj koji se karakterizira ozbiljnom hipoplazijom cakline, neuspjelom nicanjem zuba, intrapulpnim kalcifikacijama, povećanom gingivom i nefrokalcinozom.^[9]
