What this research studies
Researchers will use clinical records, DNA samples, and genetic data already collected by the DDD-Africa project to look for hidden genetic changes. They will run multiple computer tools on exome data to find structural DNA variants and search genome-wide methylation patterns that can point to specific diagnoses. A phenotype-aware AI program will match medical features with genetic findings to improve how well a genetic change explains a child's condition. The team aims to increase the number of African children who receive a genetic diagnosis and to make the data more useful for future discoveries.
Who could benefit from this research
Good fit: Children from Africa with developmental disorders or intellectual disability who have not yet received a genetic diagnosis and whose families can provide clinical information and DNA samples are the best candidates.
Not a fit: People whose conditions are caused by non-genetic factors, who cannot provide DNA or clinical records, or whose genetic cause lies outside what exome or methylation testing can detect may not benefit.
Why it matters
Potential benefit: If successful, this work could give more African families clear genetic diagnoses that guide medical care, surveillance, and family planning.
How similar studies have performed: Related efforts like the UK Deciphering Developmental Disorders program have improved diagnostic rates using exome sequencing, CNV calling, methylation signatures, and phenotype-matching tools, but these methods have been less widely applied in African populations.
