Table 3.
The relation of the significant SNPs and CNVs based on published database.
Total | Significant SNPs (bp) | Whole genome (bp) |
---|---|---|
20,726 | 3,095,677,412 | |
Within the common CNVs | 2,042 | 130,618,321 |
Outside the common CNVs | 18,684 | 2,965,059,091 |
OR with 95% CI | 2.41 (2.37-2.60) | |
p | <1×10−6 | |
Within the pathogenic CNVs | 20,658 | 3,022,313,748 |
Outside the pathogenic CNVs | 68 | 73,363,664 |
OR with 95% CI | 1.02 (1.00-1.04) | |
p | 0.03 | |
Within the pathogenic CNVs (<10 Mb) | 20,116 | 2,842,153,180 |
Outside the pathogenic CNVs (<10 Mb) | 610 | 253,524,232 |
OR with 95% CI | 1.06 (1.04-1.08) | |
p | 1.8×10−8 |
The distribution of SNPs in regions with or outside CNVs was compared using Pearson χ2 test (two-sided). The significant SNPs collected from the National Human Genome Research Institute (NHGRI) Catalog of Published GWAS was matched with the locations of common CNVs (population frequency > 1%) acquired from the Database of Genomic Variants (DGV) and pathogenic CNVs acquired from the UCSC database.
Abbreviation: SNP, single nucleotide polymorphisms; CNV, copy number variant; OR, odds ratio; CI, confidence interval.
