Identifying genetic factors linked to unexpected infant deaths

Risk Stratification of Sudden Unexpected Death in Infant Based on Biomarkers - Identification of Genetic Variants Associated With Unexpected Infant Death Syndrome

Observational Nantes University Hospital · NCT06244433

This study is trying to find new genetic links to sudden infant death syndrome (SIDS) by looking at the DNA of babies who have died unexpectedly and their parents.

What this trial studies

This multicenter genetic study aims to identify new genetic variants associated with sudden infant death syndrome (SIDS) through whole-genome sequencing of family trios. The study will include cases of sudden unexpected death in infants (SUDI) both retrospectively from a national registry and prospectively at referral centers. Whole genome sequencing will be performed on identified SIDS cases and their biological parents to analyze potential pathogenic allelic variants. The research is part of a larger project exploring genetics, neurobiology, and radio-anatomy related to SUDI.

Who should consider this trial

Good fit: Ideal candidates include infants aged 0 to 2 years who have experienced sudden unexpected death and their biological parents.

Not a fit: Patients with known metabolic, genetic, or syndromic pathologies at the time of death will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a better understanding of genetic factors contributing to SIDS, potentially informing prevention strategies.

How similar studies have performed: Other studies exploring genetic factors in SIDS have shown promise, but this specific approach using whole-genome sequencing is relatively novel.
