Variant effect prediction

Course Date: Tuesday 31th October to Friday 3th November 2017, Breda (NL)

This course is organised in collaboration with Dr. J.T. den Dunnen, Human Genetics & Clinical Genetics, LUMC, Leiden

Aim of the course:
DNA sequencing, incl. NGS, is a standard technology used in most modern laboratories. When the focus is on the identification of variants in the sequence, the next challenge is to evaluate these variants and their potential consequences. The "Variant Effect Prediction" course has been developed to show what one can do to predict the consequences on DNA, RNA and protein level, i.e. to classify the variants


This course has been developed for technicians and PhD students working in a DNA laboratory (e.g. research and clinical diagnostic laboratories) who are involved in DNA sequencing data analysis. Participants are expected to bring their own laptop (PC or Mac) as this will be needed for the course. Participants can bring their data/from an article for some of the practical sessions.

Course structure:  

We offer a 4-day course consisting of a series of lectures on variants and variant effect prediction on both the DNA, RNA and protein level. Furthermore, we will show how these variants can be viewed in genome browsers, and give an overview of variant effect prediction softwareand including "hands-on" data analysis practicals. All participants will receive a course manual.

Topics included in the course:

Preliminary course program:

Day 1
Variants: The basics

Variants in the genome, position and possible consequences Calling DNA variants (SNV, SV and CNV) and limitations from sequencing technologies
HGVS nomenclature - describing variants
DNA variants - the big databases

Day 2
Variants: Gathering information

Gene variant databases and the importance of sharing information
Human Phenotype Ontology (HPO)
Potential consequences on RNA level
Viewing data using a genome browser

Computer Practicals (parallel sessions):
genome browser (Ensembl, UCSC)
Variant nomenclature (Mutalyzer) Submiting data to a database (LOVD, ClinVar)

Day 3
Predicting consequences and variant classification

Potential consequences on protein level
Protein prediction tools
Variant classification using ACMG recommendations
Variant annotation using VEP

Computer practical (parallel sessions):
ACMG classification

Day 4
Functional testing and reporting

Functional testing; animal models and lab testing
NIPT, liquid biopsies, quality standards and reporting results Future developments


Avans Hogeschool reserves the right to substitute speakers, and change the theoretical and practical program, in order to cover most current and future new sequening technologies applications.
