Among ongoing pregnancies without a causal anomaly on microarray, 30% (95% CI 8.5%\u201060%) showed intellectual disability. Postnatal magnetic resonance imaging and physical examination often (64%; 95% CI 38%\u201085%, and 64%; 95% CI 38%\u201085%, respectively) revealed additional physical anomalies in cases without a causal anomaly on microarray. Two cases appeared truly isolated after birth. Postnatal sequencing in 4 of 16 cases without a causal anomaly on microarray but with intellectual disability and\/or additional postnatal physical anomalies revealed 2 single\u2010gene disorders. Therefore, the estimated diagnostic yield of ES in chromosomally normal cACC fetuses is between 2\/4 (50%; 95% CI 11%\u201089%) and 2\/16 (13.3%; 95% CI 2.4%\u201036%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In accordance with current guidelines, we conclude that microarray should be offered in case of isolated cACC on ultrasound.
