Exploring the Relationship Between Advanced Multimodal Brain MRI Phenotypes, Genes and Cognitive Outcome in Adults With CHD
Boston Children's Hospital
Summary
The main purpose of this proposal is to perform novel MRI analyses to determine the brain organizational changes associated with altered executive function and the modulating role of variants in neuroresilience and hypoxia response genes in adults with d-transposition of the great arteries (d-TGA).
Description
Aim 1 is structured to determine the relationship between sulcal patterns(measured by MRI) and executive function in adults with d-TGA and if this relationship is modified by (a) presence of neuroresilience gene ApoE ε2 or ε4 alleles, or (b) damaging variants in hypoxia response genes. Aim 2 is designed to determine the relationship between structural connectivity using rich club (measured by MRI) and executive function in adults with d-TGA and if this relationship is modified by (a) presence of neuroresilience gene ApoE ε2 or ε4 alleles or (b) damaging variants in hypoxia response genes.
