简要总结
This is a multicenter genetic study aimed at identifying new genes/variants associated with sudden infant death syndrome (SIDS) based on whole-genome sequencing of family trios
详细描述
The present project is part of a more global project called BIOMINRISK for which 3 axes will be explored: Genetics (a project which will be detailed here), Neurobiology and Radio-anatomical.
This is a multicenter (15 centers), national, non-randomized, open-label, genetic study. Sudden unexpected death in infant (SUDI) cases will be included (i) partly retrospectively (infants already included in the national French SUDI registry) and (ii) for the other cases, prospectively at the time of care of the deceased infant by the referral center of SUDI participating in the project. The parents making up the trios will be included prospectively.
Once the Sudden infant death syndrome (SIDS) cases have been identified among all the included SUDI cases (following the results of post-mortem examinations), Whole Genome Sequencing (WGS) will be carried out on these SIDS cases and their two parents, in order to identify pathogenic allelic variants. The data generated by this sequencing will then be analyzed using a trio approach to search for de novo variants, i.e. variants present in the infant who died of SIDS and absent from the genome of both parents.
