Summary of identified CNVs by PennCNV software on chromosome 1 for the 302 normal subjects from HapMap
| State | Mean of CNV lengths (kb) | Median of CNV lengths (kb) | Total number of CNVs (%) | LRR mean | LRR variance |
|---|---|---|---|---|---|
| cn = 0 | 24.16 | 30.35 | 409(23) | −1.28 | 0.65 |
| cn = 1 | 56.22 | 28.60 | 820(46) | −0.51 | 0.18 |
| cn = 3 | 167.26 | 63.45 | 378(21) | 0.31 | 0.08 |
| cn = 4 | 35.42 | 31.07 | 181(10) | 0.58 | 0.11 |
| cn = 2 | – | – | – | −0.004 | 0.05 |
cn = 0: deletion of double copies; cn = 1: deletion of a single copy; cn = 3: duplication of a single copy; cn = 4: duplication of double copies; cn = 2: normal state. LRR mean: the average value of LRR across all samples; LRR variance: the variance of the LRR across all samples
