Germline pathogenic variants in isocitrate dehydrogenase 1 (IDH1) can lead to a rare neurodevelopmental disorder called metaphyseal chondromatosis with D-2-hydroxyglutaric aciduria, including severe skeletal and cerebral anomalies. To the best of our knowledge, no prenatal case of an IDH1 pathogenic variant has been reported in literature. Somatic sequence variants in IDH1/2 genes are described in distinct cancers, premalignant diseases and rare inherited metabolic disorders. Amniocentesis and further genetic testing including trio exome sequencing were performed due to suspicious findings on a second trimester routine prenatal ultrasound examination...

The MYH3 gene encodes the embryonic myosin heavy chain, which is crucial for the skeletal and muscular development. The MYH3 variants are associated with distal arthrogryposis type 2A (Freeman-Sheldon syndrome), distal arthrogryposis type 2B3 (Sheldon-Hall syndrome), CPSFS1A (Contractures, pterygia, and spondylocarpostarsal fusion syndrome 1A) and CPSFS1B, which have some shared characteristics and great variability of clinical phenotypes. In this study, we report two novel MYH3 missense variants c.1024T>G (p...

We report a case of a female fetus born to an unrelated couple with a complex fetal phenotype of a pleural effusion, a cardiac malformation, and syndactyly of the toes. Prenatal exome sequencing identified a variant of uncertain significance in the PORCN gene that was upgraded to likely pathogenic following postnatal clinical examination. The phenotype described in cases with variants in the PORCN gene is often associated with findings that cannot be prospectively diagnosed by ultrasonography. This is the first report of a prenatal phenotype involving a fetal effusion associated with variants in the PORCN gene, with skeletal findings identified later in gestation on ultrasonography...

OBJECTIVE: Carrier screening with reflex to single-gene noninvasive prenatal testing (sgNIPT) is an alternative approach for identifying pregnancies at risk for inherited autosomal recessive conditions without the need for a sample from the reproductive partner. This study is the largest clinical validation of this approach in a general population setting. METHODS: The clinical performance of carrier screening with reflex to sgNIPT for cystic fibrosis, spinal muscular atrophy, alpha thalassemias, and beta hemoglobinopathies was assessed by collecting pregnancy outcome data on patients who underwent this testing and comparing the neonatal outcome to the assay-predicted fetal risk...

A Jewish couple of mixed origin was referred for genetic counseling following termination of pregnancy at 18 weeks of gestation due to severe ventriculomegaly with aqueduct stenosis. Trio exome sequencing revealed a loss-of-function heterozygous variant in the SMARCC1 gene inherited from an unaffected mother. The SMARCC1 gene is associated with embryonic neurodevelopmental processes. Recent studies have linked perturbations of the gene with autosomal dominant congenital hydrocephalus, albeit with reduced penetrance...

Heterozygous loss-of-function variants in the PKD1 gene are commonly associated with adult-onset autosomal dominant polycystic kidney disease (ADPKD), where the formation of renal cysts depends on the dosage of the PKD1 gene. Biallelic null PKD1 variants are not viable, but biallelic hypomorphic variants could lead to early-onset PKD. We report a non-consanguineous Chinese family with recurrent fetal polycystic kidney and negative findings in the coding region of the PKHD1 gene or chromosomal microarray analysis...
