In most cases, it is expected that all samples will be collected and phenotyped before applying for the NIH CIDR Program. Possible exceptions should be discussed with CIDR and the NIH supporting institute before applying.

- Sample pretesting with 96 SNP barcode panel for all samples, 10% of samples will also have a high density SNP array run to better assess sequencing variant calling quality
- This allows us to:
- Determine SNP genotypes for sample tracking and sequencing variant call QC purposes
- Identify file and/or aliquoting errors (primarily gender and/or Mendel discrepancies)
- Identify unexpected 1st degree relatives among subjects, confirm expected relationships
- Identify samples that perform poorly
- Identify unexpected duplicate samples, confirm expected duplicates
- Inclusion of study duplicates and HapMap controls.
- Data will be generated to a minimum completeness level of > 95% coverage at 8X.
- Data will be generated to a minimum high density SNP array concordance of >99% within targeted regions.
- SNVs and indels called and annotated
- Data quality evaluated using a robust alignment and variant calling workflow implemented via CIDRSeqSuite in-house pipeline. Any of the files detailed in the analysis workflow will be available for distribution to the PI. Image and intensity level data is not retained.
Only high coverage sequencing of individual samples are supported. We cannot accommodate the analysis of pooled samples or low coverage study designs at this time.
CNV detection utilizing “counting” methods are also not likely to be highly successful due to the uneven coverage inherent with enrichment chemistry.
