Default region of interest kits

A region of interest (ROI) BED file determines which genomic regions will be included in the variant analysis. It functions as a preprocessing filter, determining which variants proceed to annotation and interpretation.

Default ROI kits by case type

If no custom ROI BED kit is applied to a case, the system applies a default ROI BED file based on the case type. All default ROI BED files are available for download (see Default ROI kit details).

Full Genes

A wide range of genomic regions BED file. It contains:

• "RefSeq ALL" transcripts and "GENCODE" full genes regions with 5Kbp upstream and 5Kbp downstream

• Within this range, all “Clinical Regions” are included

• All dosage regions (HI/TS sig level 1, 2 or 3)

Moreover, liftover versions of both reference regions were included, for the current and previous range versions.

Sources:

• Liftover done using CrossMap (v0.5.2), chain hg19ToHg38.over.chain.gz

• NCBI RefSeq regions are based on the release 105 (hg19) and 110 (hg38)

• Gencode regions are based on the release V19 (hg19) and V41 (hg38)

• All microRNA genes based on HGNC miRNA definition December 2022

• ClinGen Dosage region Dec 2022

• Promoters from EPDnew human version V6

• mtDNA CRS

• RNA disease genes based on OMIM and HGNC (Dec 2022): ATXN8OS, TERC, IL12A-AS1, FAAHP1, NUTM2B-AS1, GAS8-AS1, RNU12, MIR204, IGHG2, SLC7A2-IT1, MIR99A, RMRP, XIST, MEG3, DIRC3, MIR17HG, GNAS-AS1, LRTOMT, LINC00299, DUX4L1, MIR137, MIR140, MIR605, SNORD118, RNU4ATAC, HELLPAR, IGHG1, IGHM, MIR19B1, RNU7-1, LINC00237, MIR2861, MIR4718, IGHV3-21, IGHV4-34, IGKC, KCNQ1OT1, MIR184, MIR96, H19, HYMAI, PCDHA9, UGT1A1, AFG3L2P1, DISC2, SNORA31, TRU-TCA1-1, PCDHGA4, TRAC, ECEL1P3, MIAT

• ClinVar variants (ClinVar Dec- 2022) with any pathogenic or likely pathogenic significance (and some drug responses that are affiliated with pathogenicity)

• 50K STR regions based on the Dragen4.0 Specification file

CNV variants are not confined to regions of interest.

Clinical Regions

This is a BED file that includes every clinically relevant region. The following are included:

• “RefSeq Curated” and “GENCODE” regions with flanking areas of 50bp from each side 5UTR and 3UTR region for protein coding genes (based on RefSeq)

• OMIM disease-related RNA genes (flanking 50bp)

• All Clinvar Pathogenic variants regions (flanking 50bp)

• Promoters region (EPDnew human version 006, flanking 50bp)

• Known STR regions (Dragen 4.0 specification file)

• All microRNA genes (flanking 50bp based on HGNC)

• Full mtDNA region

For consistency, the GRCh38 version includes the lifted over regions of GRCh37 (liftover using CrossMap).

CNV variants are not confined to regions of interest.
