Exploring Genes and Variants with Ensembl


Today11.00 - 11.45

• Introduction to Genome Browsers

• Genes and Transcripts

• Variation

14.00 - 15.30 or 16.00 - 17.30• Browsing

• Genes and Transcripts

• Variants

• Assembly Converter


Tomorrow: 11 - 11.45

• Variant Effect Predictor

The VEP determines the effects of your variants

(SNPs, insertions, deletions, CNVs or structural

variants) on genes, transcripts, and protein

sequence, as well as regulatory regions.


Objectives

• What is Ensembl?

• What type of data can you get in Ensembl?

• How to navigate the Ensembl browser website

• How to use Ensembl tools

• Where to go for help and documentation

Introduction

Why do we need genome browsers?

1977: 1st genome to be sequenced (5 kb)

2004: ‘Finished’ human sequence (3 Gb)

2015: Completion of 1000 Genomes project

Ensembl and Havana annotation

Automatic annotation Manual annotation


Automatic gene annotation

• Genome-wide determination using the Ensembl automated pipeline

• Predictions based on experimental (biological) data

• Predictions based on the genomic sequence (ab initio)


Transcript annotation


Other species

• Infer genes from homology to other species• Eg predict genes in by mapping cDNAs/proteins

from to the genome

• RNAseq data


Manual gene annotation

• Gene determination on a case-by-case basis by a person

•

• Genome-wide

• Genes list

• vega.sanger.ac.uk


GENCODE

• The GENCODE gene set is made up of:

• Ensembl automatically annotated genes

• Havana manually annotated genes

• The merged gene set

• default gene set for

• ENCODE

• 1000 genomes

• and lots of other major projects


Merged ‘Golden’ transcripts• Identical annotation

• Higher confidence and quality

CCDS transcripts• Consensus coding DNA sequence set

• Agreement between EBI, WTSI, UCSC and NCBI

Why Gene Ontology (GO)?

Innate immunity

Non-specific immunity

Phagocyte

Complement Cytokines Natural killer cells

Multiple terms for the same thing

Gene descriptions too specific

Mast cells

GO terms form a controlled vocabulary

Variation


Variant sources

http://www.ensembl.org/info/genome/variation/sources_documentation.html#homo_sapiens


Variant types

1) Small scale in one or few nucleotides of a gene

• Small deletions and insertions (DIPs or indels)

• Single nucleotide polymorphism (SNP)

A G A C T T G A C C T G T C T - A A C T G G AT G A C T T G A C - T G T C T G A A C G G G A

2) Large scale (>50bp) in chromosomal structure (structural variant)

• Copy number variants (CNV)

• Large deletions/duplications, insertions, translocations

deletion duplication insertion translocation
