Genetics of Ventriculo-arterial Discordance: Towards a PRECIsion Medicine in PEDiatric Cardiology
Number of centres planned : 16 centres in France
Type of study / Study design : Research Involving the Human Person category 2.
Multicentric. Prospective
Planning of the study : Total duration: 57,5 months. Recruitment period: 33.5 months. Follow-up time per patients : 2 years
Expected number of cases : The study will involve a maximum of 900 individuals, from 16 centers in France300 family trios (consisting of 150 index cases and their 2 parents, healthy volunteers, N= 450 individuals)
- In the event of unavailability, refusal, non-compliance with an inclusion or exclusion criterion concerning one of the biological parents, only the index case (patient) will be included in the study without his or her parents.
The 300 index cases with ventriculo-arterial discordance will be divided into two groups: 100 double discordance cases and 200 large-vessel transpositions.
These group inclusion targets are theoretical. If the proportion of patients available for inclusion turns out to be higher than expected for one of the groups, the targets may be adjusted, while maintaining a maximum of 300 cases included (corresponding to 900 subjects if all trios are complete).
Patients and their parents will be informed of the study by their referring cardiologist, and their written consent will be obtained.

Treatment, procedure, combination of procedures under consideration :
* Blood samples for genetic analyses collected at the inclusion visit for patients and parents in case of trio families
Schedule of different visits and examinations :
Inclusion visit:
* Collection of demographic, clinical data from the index case and parents * DNA sampling for genetic research (biocollection) of the index case or family trio * Completion of the quality of life questionnaire
Annual visit with a 2 years follow-up:
* Retrieval of data from the index case * Completion of the quality of life questionnaire
