Funkcija

uredi

Ovaj gen kodira transmembranski protein, koji se primarno nalazi u endoplazmatskom retikulumu i sveprisutno eksprimiran sa najvišim nivoima u mozgu, pankreasu, srcu i insulinskim linijama beta-ćelija.[7] Čini se da Wolframin funkcionira kao kationski selektivni ionski kanal.[9]

Klinički značaj

uredi

Mutacije u ovom genu povezane su sa Wolframovim sindromom, koji se također naziva DIDMOAD (Diabetes Insipidus, Diabetes Mellitus, optička atrofija i deafness = gluhoća), autosomno recesivnim poremećajem. Bolest karakterizira neimunski insulinski zavisni dijabetes melitus i bilateralna progresivna optička atrofija, koja se obično javlja u djetinjstvu ili ranoj odrasloj dobi. Različiti neurološki simptomi, uključujući predispoziciju za psihijatrijsku bolest, također mogu biti povezani s ovim poremećajem. Veliki broj i raznovrsnost mutacija u ovom genu, posebno u egzonu 8, može biti povezana sa ovim sindromom. Mutacije u ovom genu također mogu uzrokovati autosomno dominantnu gluhoću 6 (DFNA6), također poznatu kao DFNA14 ili DFNA38.[7]

Mutacije ovog gena su takođe povezane sa kongenitalnim kataraktom.[10]
