Pan African Bioinformatics Network for H3Africa

Bioinformatics analysis and annotation of variants in NGS data

This workshop is closed. The training material is available at: http://training.h3abionet.org/h3a2016ngs/?page_id=2

Dates for the workshop: 4th April to 6th April 2016

Venue of workshop: Health Teaching Labs 1, Basement of Anatomy Building, UCT Medical School, Cape Town, South Africa

Workshop organisers and sponsors: H3ABioNet, African Pharmacogenomics Research Consortium, CBIO.

Workshop trainers and support: Amel Ghouila, Gerrit Botha, Colleen Saunders, Luiz Olavo Bonino, Nyarai Soko, Suresh Maslamoney, Sumir Panji, Collet Dandara and Nicola Mulder.

Course Overview: This workshop provides an introduction to the computational analyses of NGS data from pre-processing to the identification and annotation of genomic variants and the functional effects of those variants, as well as the use of pharmocogenomic databases.

Intended Audience: This workshop is aimed at attendees of the 3rd Pharmacogenetics and Precision Medicine Conference in Africa, geneticists, genetic counselling students/researchers, clinicians and healthcare professionals interested in the use of genomic data for personalising treatment.

Syllabus and Tools: Participants will learn about the handling of NGS data, identification of genomic variants, curated databases that have genomic information/sequences for use; analysis of sequences to look for mutations; evaluation of the significance of mutations observed, pathogenesis and prediction of the functional significance of these variants.

Prerequisites: Participants are encouraged to work through the following resources to enable them to gain the most from the workshop:


  • Participants will learn how to execute a web based NGS workflows using Galaxy.
  • Participants should come out understanding how to obtain and analyse variants, particularly from NGS data.
  • Participants should come out with knowledge on how to predict the significance of identified mutations, checking for pathogenesis, or whether they affect regulatory regions.
  • Participants should come out with knowledge on the possible clinical significance (pharmacogenomics relevance) of variants.

Workshop limitations: This workshop will provide a foundation for continued learning in the bioinformatics handling of NGS data, identification, annotation and functional prediction effects of variants. The workshop will not make one an expert on NGS data, filtering, functional predication and annotation of variants.
