Abstract | Genetic variants in TMEM106B are a common risk factor for frontotemporal lobar degeneration and the most important modifier of disease risk in patients with progranulin (GRN) mutations (FTLD-GRN). TMEM106B is encoding a lysosomal transmembrane protein of unknown molecular function. How it mediates its disease-modifying function remains enigmatic. Several TMEM106B single nucleotide polymorphisms (SNPs) are significantly associated with disease risk in FTLD-GRN carriers, of which all except one are within intronic sequences of TMEM106B. Of note, the non-coding SNPs are in high linkage disequilibrium with the coding SNP rs3173615 located in exon six of TMEM106B, resulting in a threonine to serine change at amino acid 185 in the minor allele, which is protective in FTLD-GRN carriers. To investigate the functional consequences of this variant in vivo, we generated and characterized a knockin mouse model harboring the Tmem106b |
