Bone mineral density and genetic markers involved in three connected pathways (focal adhesion, actin cytoskeleton regulation and cell cycle): The CUMAGAS-BMD information system

Abstract

The focal adhesion, the actin cytoskeleton and cell-cycle are connected pathways and their genes are implicated in the pathogenesis of low BMD. Data from 211 studies that investigated the association between BMD and gene variants involved in these pathways were catalogued in a web-based information system and analyzed. In individual studies, significant association was found for 16 variants in lumbar spine, 11 in femoral neck and 5 in hip. In meta-analysis, significant results were shown for the variants COL1A1 rs1800012 (in lumbar spine and femoral neck), COL1A1 rs1107946 (in lumbar spine), TGFB1 rs1982073 (in femoral neck and hip) and TGFB1 rs1800469 (in lumbar spine). © 2011 Informa UK, Ltd.
