dc.description.abstract | Osteoporosis is a complex disorder and commonly leads to fractures in elderly persons. Genome-wide association studies
(GWAS) have become an unbiased approach to identify variations in the genome that potentially affect health. However,
the genetic variants identified so far only explain a small proportion of the heritability for complex traits. Due to the modest
genetic effect size and inadequate power, true association signals may not be revealed based on a stringent genome-wide
significance threshold. Here, we take advantage of SNP and transcript arrays and integrate GWAS and expression signature
profiling relevant to the skeletal system in cellular and animal models to prioritize the discovery of novel candidate genes
for osteoporosis-related traits, including bone mineral density (BMD) at the lumbar spine (LS) and femoral neck (FN), as well
as geometric indices of the hip (femoral neck-shaft angle, NSA; femoral neck length, NL; and narrow-neck width, NW). A
two-stage meta-analysis of GWAS from 7,633 Caucasian women and 3,657 men, revealed three novel loci associated with
osteoporosis-related traits, including chromosome 1p13.2 (RAP1A, p = 3.661028), 2q11.2 (TBC1D8), and 18q11.2 (OSBPL1A),
and confirmed a previously reported region near TNFRSF11B/OPG gene. We also prioritized 16 suggestive genome-wide
significant candidate genes based on their potential involvement in skeletal metabolism. Among them, 3 candidate genes
were associated with BMD in women. Notably, 2 out of these 3 genes (GPR177, p = 2.6610213; SOX6, p = 6.4610210)
associated with BMD in women have been successfully replicated in a large-scale meta-analysis of BMD, but none of the
non-prioritized candidates (associated with BMD) did. Our results support the concept of our prioritization strategy. In the
absence of direct biological support for identified genes, we highlighted the efficiency of subsequent functional
characterization using publicly available expression profiling relevant to the skeletal system in cellular or whole animal
models to prioritize candidate genes for further functional validation. | en_US |
