    Abstract Noninvasive cfDNA testing for monogenic disorders (sgNIPT) has become integrated into the care of pregnant women at increased risk based on carrier status, known family history, or ultrasound anomalies. The availability of commercial tests for common autosomal recessive and de novo autosomal dominant conditions has led to the use of these tests in low-risk pregnancies. However, is the technology ready for use in this low-risk population? This report is a summary of the debate on this topic at the 27

    Abstract Cell-free fetal DNA (cffDNA) is released into the maternal circulation from trophoblastic cells during pregnancy, is detectable from 4 weeks and is representative of the entire fetal genome. The presence of this cffDNA in the maternal bloodstream has enabled clinical implementation of non-invasive prenatal diagnosis (NIPD) for monogenic disorders. Detection of paternally inherited and de novo mutations is relatively straightforward, and several methods have been developed for clinical use, including quantitative polymerase chain reaction (qPCR), and PCR followed by restriction enzyme digest (PCR-RED) or next-generation sequencing (NGS). A greater challenge has been in the detection of maternally inherited variants owing to the high background of maternal cell-free DNA (cfDNA). Molecular counting techniques have been developed to measure subtle changes in allele frequency. For instance, relative haplotype dosage analysis (RHDO), which uses single nucleotide polymorphisms (SNPs) for phasing of high- and low-risk alleles, is clinically available for several monogenic disorders. A major drawback is that RHDO requires samples from both parents and an affected or unaffected proband, therefore alternative methods, such as proband-free RHDO and relative mutation dosage (RMD), are being investigated. cffDNA was thought to exist only as short fragments (<500 bp); however, long-read sequencing technologies have recently revealed a range of sizes up to ∼23 kb. cffDNA also carries a specific placental epigenetic mark, and so fragmentomics and epigenetics are of interest for targeted enrichment of cffDNA. Cell-based NIPD approaches are also currently under investigation as a means to obtain a pure source of intact fetal genomic DNA.

    Abstract Skeletal dysplasias are a heterogeneous group of conditions, many of which present unexpectedly in the prenatal period with a variety of ultrasound findings. Accurate prenatal diagnosis can now be facilitated using exome sequencing approaches, but in order to interpret results, accurate and detailed phenotyping is required. Here, we describe the sonographic approach to the prenatal diagnosis of skeletal abnormalities and illustrate how taking a systematic approach can facilitate diagnosis.
