The data obtained may help to revise the management strategy for the current pregnancy and assist in determining the risk of recurrence of Noonan syndrome in this parental couple.</p> <p><bold>Materials and methods:</bold> Pregnant women with NIHF underwent invasive prenatal diagnostics, followed by genetic testing using molecular karyotyping on DNA microarrays and whole exome sequencing.</p> <p><bold>Results:</bold> The study presents the clinical observations of three cases of NIHF associated with Noonan syndrome in the fetus. Married couples were examined and the inheritance pattern of variants associated with Noonan syndrome was determined. Genetic counseling was provided to the families, and a method for planning subsequent pregnancies was established.</p> <p><bold>Conclusion:</bold> Whole exome sequencing enables the diagnosis of Noonan syndrome in patients with NIHF, provides an estimation of fetal prognosis, and expands the scope of genetic counseling for the couple.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность:</bold> Проведение расширенного генетического тестирования на основании полноэкзомного секвенирования позволяет диагностировать синдром Нунан у беременных с неиммунной водянкой плода (НИВП).
