Chromosomal microarray analysis utilizing an Affymetrix CytoScan 750k SNP array was employed to detect pathogenic copy number variations (CNVs). Trio exome sequencing was used to detect monogenic conditions. Clinical and laboratory data were collected and reviewed for these cases, including maternal demographics, prenatal sonographic findings, molecular testing sequencing results, and pregnancy outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All cases had unremarkable first\u2010trimester ultrasound scans without reporting limb malformations. Seven cases presented with abnormal second\u2010trimester ultrasounds: three instances of cardiac defects, two instances of limb abnormalities (one with short long bones and one with duplication of big toes), one case of intracranial malformation (dysgenesis of the corpus callosum), and one instance of restricted fetal growth. Five pregnancies exhibited abnormal sonographic signs in the third trimester: two cases of restricted fetal growth, one with clubfeet and polyhydramnios, one with hypospadias, and one with isolated polyhydramnios.
