Model-organizmi korišteni su u proučavanju funkcije KPTN-a. Uslovna linija nokaut-miša, zvana Kptn tm1a(EUCOMM)Wtsi[16][17] generirana u okviru programa Međunarodni konzorcij za nokaut-miševe – visokopropusnog projekta mutageneze za generiranje i distribuciju životinjskih modela bolesti zainteresiranim naučnicima.[18][19][20]
Muške i ženske životinje prolazile su standardizirani fenotipski pregled, kako bi se utvrdili efekti delecije.[14][21] Izvedena su 22 testa na mutantnim miševima i uočeno je šest značajnih abnormalnosti.[14] Homozigotni mutirani miševi su imali hiperalbuminemiju, smanjen broj zrelih B-ćelija i povećanu osjetljivosti na bakterijsku infekciju. Ženke su također imale povećanu tjelesnu težinu, tjelesnu masnoću i smanjenu toleranciju glukoze.[14]
Klinički značaj
urediMutacije u ovom genu povezane su sa sindromom akrocefalije, mišićne hipotonije, globalnog kašnjenja u razvoju, dispraksije i sinkinezije ruku i usta.[22]
