Axiom Goat v2 chip final design (Thermofisher)

New

The Axiom Caprine Genotyping v2 Array was designed in collaboration with the International Goat Genome Consortium and the VarGoats Consortium. It contains all the SNPs from the Illumina Goat_IGGC_65K_v2 minus 760 monomorphic SNPs, which itself overlaps the Illumina GoatSNP50 chip (53372 SNPs) design. In addition, it contains the ancestral markers selected for the IMAGE multi-species goat chip (1042 SNPs). This array also includes 261 structural variants. 135 of these were tiled as copy number regions and 126 were tiled with junction probes (966 SNPs).

The final set then contains 59,795 SNPs and 265 structural variants.

384 animals are currently genotyped on this chip to validate it and give MAF of the markers in an international panel.

Two formats are available:

Design (with location of the SNPs on ARS1 assembly):

GGP Goat 70k chip (NeoGen/Geneseek)

New

Main features:

  • overlap with the GoatSNP50 Illumina beadchip is around ~40,000,
  • remaining 30,000 SNPs of content that does not overlap were selected to segregate in both fiber and dairy goat breeds with whole genome sequence data on nearly 300 animals,
  • includes Parentage SNPs and Scrapie.

10K IMAGE (Thermofisher)

New

It contains:

  • 8000 SNPs from Illumina GoatSNP50, included 195 parentage SNPs,
  • 1000 SNPs in candidate genes (DGAT1, PIS, PRP, sexual and mitochondrial chromosomes…),
  • 1000 ancestral SNPs.

See IMAGE project deliverable.

50K SNP chip version 2

Goat_IGGC_65K_v2 is the version 2 of the GoatSNP50 Illumina chip and is available since january 2021.

This version 2 contains a final number of 59,727 SNPs described here.

The manifest file in bpm format (version 2 since January 22, 2021) and the cluster file are also downloadable.

The csv file gives the information contained in the bpm file with a more accurate SNP location.

Finally, as we had to reduce the information for the SNP location in the bpm file (see below), an auxiliary file is also downloadable. The auxiliary file is a table that you can import into GenomeStudio as additional columns and it will give you the information that the manifest file cannot contain.

The probes have been mapped on ARS1 assembly with the following naming of chromosomes/scaffolds:

  • 1 to 29
  • MT
  • X.1 X.2 for scaffold assigned to X in the auxiliary and csv files, X in the bpm file
  • Y.1 to Y.11 for scaffolds assigned to Y in the auxiliary and csv files, Y in the bpm file
  • 0.scaffold_name…for unplaced scaffold (example: 0.NW_017191871.1) in the auxiliary and csv files, 0.NW_scaffold in the bpm file.
For probes either unlocalized or with multiple localizations or not confirmed as belonging to X or Y scaffolds (after studying the genotypes), localization was set to null.

The final number of SNPs per chromosome/scaffold is available here.

VarGoats project

VarGoats is the first step of a 1000 goat genomes project and is lead by Gwenola Tosser-Klopp (INRA, France).

PacBio genome assembly annotation: submit your transcriptomics data

Ensembl will annotate the goat genome assembly (GCA_001704415.1, submitted by USDA ARS 2016/08/24). The annotation is planned for release in the 2017 summer. Transcriptomics data are a valuable tool to annotate genomes. I thus encourage you to make your transcriptomics data accessioned and publicly available by 31st January 2017.
If you need any help for the submission, please contact: Data submission at EBI.
Before submitting your data, look at the FAANG documentation and the FAANG standards. If you follow these, any data you create will also be integrated into the FAANG resource.
