Abstract:	SORL1 gene variants were described as risk factors of Alzheimer's disease (AD). We investigated the association of four SORL1 variants with CSF levels of A{beta}42 and A{beta}40 in 153 AD patients recruited from a multicenter study of the German Competence Net Dementias. Only one SORL1 SNP was associated with altered A{beta}42 levels in the single marker analysis (SNP21: p=0.011), the other SNPs did not show an association with A{beta}42 or A{beta}40 CSF levels. Haplotype analysis identified a three marker SORL1 haplotype consisting of SNP19 T-allele, SNP21 G-allele and SNP23 A-allele (T/G/A) which was associated with reduced A{beta}42 CSF levels in AD patients (p=0.003). A{beta}40 levels were also lower in carriers of this haplotype; however, this did not reach statistical significance (p=0.15). We found a SORL1 haplotype which was associated with CSF levels of amyloid-{beta} cleavage products, measured as altered levels of A{beta}42. Thus our data suggest that SORL1 gene variants might influence AD pathology.
