Newly identified genes listed... sciencecodex.com The search for late-onset Alzheimer's risk factor genes had taken considerable time, until the development of GWAS and other techniques. Until 2009, only one gene variant, Apolipoprotein E-e4 (APOE-e4), had been identified as a known risk factor. Since then, prior to today's discovery, the list of known gene risk factors had grown to include other players—PICALM, CLU, CR1, BIN1, MS4A, CD2AP, EPHA1, ABCA7, SORL1 and TREM2. IGAP's discovery reported today of 11 new genes strengthens evidence about the involvement of certain pathways in the disease, such as the role of the SORL1 gene in the abnormal accumulation of amyloid protein in the brain, , a hallmark of Alzheimer's disease. It also offers new gene risk factors that may influence several cell functions, to include the ability of microglial cells to respond to inflammation. The researchers identified the new genes by analyzing previously studied and newly collected DNA data from 74,076 older volunteers with Alzheimer's and those free of the disorder from 15 countries. The new genes (HLA-DRB5/HLA0DRB1, PTK2B, SLC24A4-0RING3, DSG2, INPP5D, MEF2C, NME8, ZCWPW1, CELF1, FERMT2 and CASS4) add to a growing list of gene variants associated with onset and progression of late-onset Alzheimer's.
