Objective: The study aimed to evaluate the frequency of pathogenic copy number variants (CNVs) classified as incidental findings (IFs) in prenatal diagnosis and to develop consensus recommendations for standardizing their reporting across six centers within the Catalan public health system (XIGENICS network).
Method: A retrospective review of 4219 consecutive prenatal microarrays performed within the network from 2018 to 2023 was conducted, including all referral reasons. To develop consensus recommendations, several discussion meetings were held along with an extensive review of the existing literature.
