According to the WGS study protocol all results of the WGS testing will be provided by a geneticist and genetic counselor at an informing session. At this session, results will be returned and explained, recommendations provided and questions answered (routine clinical care). Following this session, parents will be randomized as couples based on whether their child received a result of a causal variant or non-causal variant to receive either routine clinical care with an enhanced report (intervention arm) or routine clinical care first followed by enhanced report (control with crossover). Randomizing parents as couples is necessary as randomization at the individual level would lead to contamination and spillover if one member of the couple were in the usual care arm and the other in the intervention arm.
