Summary of the DNA and cDNA genotyping for the Illumina assay.
| Description | Genes | SNPs | |
|---|---|---|---|
| A | Tested on the array | 932 | 1536 |
| B | Above intensity threshold (11.25) | 446 | 576 |
| C | As in B with at least two heterozygous samples | 393 | 497 |
| D | As in C with good quality probe hybridisation in homozygotes | 214 | 261 |
| E | As in D with at least two heterozygotes significant for ASE (p < 0.01) | 49 | 56 |
| F | As in E for the candidate genes only | 39 (18.2%) | 44 (16.9%) |
Numbers of SNPs and genes that are (A) tested on the Illumina array, (B) have passed the intensity cut-off, (C) have sufficient heterozygous placentas, (D) have passed hybridisation probe quality controls and (E) for which our statistical test detected ASE. Column F is the same as E but without taking into account the imprinted control genes.
