Abstract
Several years ago reports linked an area on chromosome 12 with Alzheimer's disease.1 More recently, two groups have reported a relation between a candidate gene (LBP-1c/CP2/LSF) on chromosome 12 and modified risk of Alzheimer's disease. 2 and 3 The region of chromosome 12 where several genetic linkage studies have found high lod scores4, 5, 6, 7, 8 and 9 is shown in the figure. The pattern of findings, modest evidence of linkage across a broad region of interest, can occur in complex genetic disorders such as Alzheimer's disease but this pattern could also be a false positive. Two potential candidate genes that lie within this region are genes for α−2 macroglobulin and LDL-receptor-related protein (LRP). α−2 macroglobulin is thought to be involved in the clearance and degradation of β-amyloid, a fragment of the amyloid precursor protein (APP) that is deposited in the brains of patients with Alzheimer's disease. LRP is a receptor for apolipoprotein E and α−2 macroglobulin. Casecontrol studies suggested that variants in α−2 macroglobulin10 and LRP11 were associated with a high risk of Alzheimer's disease. However, several subsequent studies have not corroborated these findings.
