Use of CMA\/ES increased in the second study period (16.3% vs. 59.7%), resulting in more pathogenic findings (26 vs. 72 cases), whereas diagnostic yield among tested cases decreased without significance. The highest ES yield was observed in multisystem CNS anomalies; isolated CNS plus cases showed higher yields than truly isolated CNS cases.\u00a0In an exploratory subgroup analysis, isolated CNS plus cases with polyhydramnios had a higher CMA\/ES yield than truly isolated cases. Among 91 live-born children with follow-up, 49.5% (45\/91) had global developmental delay, which was more frequent with pathogenic findings (90.0%, 18\/20;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.002) and increasing anomaly complexity (11.1 to 81.8%;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Uptake of CMA and ES increased over time and resulted in more etiologic diagnoses.
