Thisled scientiststo mutation in the gene ( FLG)encoding filaggrin . This is a protein that , undernormal setting , binds to fiber of ceratin and helps to keep up the skin ’s roadblock . change toFLGhave been associated with KP , though the pathway by which these mutations lead to keratin buildup are not yet established .
Though a positively charged step , the search for a grounds is far from over , and not just limited toFLG . Some scientists suggest thatFLGmutations ca n’t answer for for all of the discernible traits of KP , nor for the differences in those trait seen between hoi polloi . In financial backing of that , a smallstudyof 20 people with KP found that only 35 percent hadFLGmutations , although they mark this is higher than the average European carrier frequency of 4 to 9 percent .
