OBJECTIVES: Standard genetic testing can fail to identify an underlying genetic etiology in pregnancies affected by multiple fetal abnormalities. Recently, whole exome sequencing (WES) studies have shown promise in recognizing genetic diagnoses where standard genetic testing does not yield answers.
CASE PRESENTATION: A 35-year-old G1P0 healthy female found at anatomy scan to have multiple fetal anomalies, including severe bilateral ventriculomegaly, renal pyelectasis, and short long bones. Karyotype and microarray were normal. Whole exome sequencing showed the fetus was compound heterozygous for likely pathogenic variants in the ROBO1 gene.
CONCLUSIONS: In the presence of multiple fetal anomalies with normal karyotype and microarray, whole exome sequencing should be considered to not only provide answers for the affected parents, but also aid in future pregnancy planning.
