Open dysraphism is diagnosed in Europe in 93.5% of cases. In case of suspicion of fetal open dysraphism, a detailed fetal morphologic assessment is required to confirm the diagnosis and exclude associated structural anomalies, as well as genetic assessment. In case of isolated fetal open dysraphism, assessment of prognosis is based on fetal imaging including the level of the lesion, the presence or not of a sac, the presence and nature of intra cranial anomalies, and the anatomical and functional evaluation of the lower extremities. Based on these biomarkers, a personalized prognosis as well as comprehensive information about prenatal management alternatives will allow parents to decide on further management options.

We aim to investigate whether the application efficacy of Asian screening array (ASA) in PGT‐M preclinical workup for the Chinese population is superior to NGS based single nucleotide polymorphism (SNP) panels.MethodsWe conducted a retrospective analysis by reviewing 294 couples from a single center over the past 4 years and compared the detection results between NGS‐based SNP panels and ASA. Using the numbers of informative SNPs upstream and downstream flanking of variants, we assessed the detection efficiency of both methods in monogenic diseases, chromosomal microdeletion syndrome and males with de novo variants, among other scenarios.ResultsResults indicate that ASA offers a greater number of informative SNPs compared with NGS‐based SNP panels. Additionally, data analysis for ASA is generally more straightforward and may require less computational resources. While ASA can address most PGT‐M challenges, we have also identified certain genes in previous tests that are not suitable for PGT‐M using ASA.ConclusionThe application of ASA in PGT‐M preclinical workup for Chinese populations has good practical value as it can perform linkage analysis for most genetic variants.
