The continuation of these accomplishments was stimulated by the 12^th international conference of AfSHG held jointly with the 1^st Congress of the Malian Society of Human Genetics (MSHG) in Bamako, Mali from September 18^th to 21^st 2019. The main theme of the conference was \"Human Genetics and Genomics as a Unifying Factor for Harmony and Progress in Africa\". The goals of the meeting were to promote the work conducted mainly by African researchers and to contribute to scientific knowledge through genetic research. Despite challenges due to security issues in Mali, this conference attracted many scientists, including key experts in genetics and associated fields, making the conference successful scientifically and geographically. Overall, 172 delegates from 24 countries attended. Sessions on various topics relevant to Africa were held. These included the genetics of infectious diseases, cancer, and rare diseases as well as bioinformatics, pharmacogenomics, population genetics, and ethical, legal, and social issues, particularly with respect to genetic research in African populations. The need for genetic data sharing to improve research and health and the focus of actionable research for African populations was stressed throughout the meeting.</p>","PeriodicalId":48190,"journal":{"name":"Pan African Medical Journal","volume":"49 ","pages":"19"},"PeriodicalIF":0.9,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11662216/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142877183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
