  • Does genomic sequencing early in the diagnostic trajectory make a difference? A follow-up study of clinical outcomes and cost-effectiveness

    PurposeTo systematically investigate the longer-term clinical and health economic impacts of genomic sequencing for rare-disease diagnoses.MethodsWe collected information on continuing diagnostic investigation, changes in management, cascade testing, and parental reproductive outcomes in 80 infants who underwent singleton whole-exome sequencing (WES).ResultsThe median duration of follow-up following result disclosure was 473 days. Changes in clinical management due to diagnostic WES results led to a cost saving of AU$1,578 per quality-adjusted life year gained, without increased hospital service use. Uninformative WES results contributed to the diagnosis of non-Mendelian conditions in seven infants. Further usual diagnostic investigations in those with ongoing suspicion of a genetic condition yielded no new diagnoses, while WES data reanalysis yielded four. Reanalysis at 18 months was more cost-effective than every 6 months. The parents of diagnosed children had eight more ongoing pregnancies than those without a diagnosis. Taking the costs and benefits of cascade testing and reproductive service use into account, there was an additional cost of AU$8,118 per quality-adjusted life year gained due to genomic sequencing.ConclusionThese data strengthen the case for the early use of genomic testing in the diagnostic trajectory, and can guide laboratory policy on periodic WES data reanalysis.

    Purpose The high percentage of patients carrying germline mutations makes pheochromocytomas/paragangliomas the most heritable of all tumors. However, there are still cases unexplained by mutations in the known genes. We aimed to identify the genetic cause of disease in patients strongly suspected of having hereditary tumors. Methods Whole-exome sequencing was applied to the germlines of a parent–proband trio. Genome-wide methylome analysis, RNA-seq, CRISPR/Cas9 gene editing, and targeted sequencing were also performed. Results We identified a novel de novo germline mutation in DNMT3A, affecting a highly conserved residue located close to the aromatic cage that binds to trimethylated histone H3. DNMT3A-mutated tumors exhibited significant hypermethylation of homeobox-containing genes, suggesting an activating role of the mutation. CRISPR/Cas9-mediated knock-in in HeLa cells led to global changes in methylation, providing evidence of the DNMT3A-altered function. Targeted sequencing revealed subclonal somatic mutations in six additional paragangliomas. Finally, a second germline DNMT3A mutation, also causing global tumor DNA hypermethylation, was found in a patient with a family history of pheochromocytoma. Conclusion Our findings suggest that DNMT3A may be a susceptibility gene for paragangliomas and, if confirmed in future studies, would represent the first example of gain-of-function mutations affecting a DNA methyltransferase gene involved in cancer predisposition.

  • Validation of Version 3.0 of the Breast Cancer Genetics Referral Screening Tool (B-RST™)
    Genet. Med. (IF 8.229) Pub Date : 2018-05-08

    Purpose Despite increased awareness of hereditary breast and ovarian cancer among clinicians and the public, many BRCA1/2 mutation carriers remain unaware of their risk status. The Breast Cancer Genetics Referral Screening Tool (B-RST™) was created and validated to easily identify individuals at increased risk for hereditary breast and ovarian cancer for referral to cancer genetics services. The purpose of this study was to revise B-RST™ to maximize sensitivity against BRCA1/2 mutation status. Methods We analyzed pedigrees of 277 individuals who had undergone BRCA1/2 testing to determine modifications to the B-RST™ 2.0 algorithm that would maximize sensitivity for mutations, while maintaining simplicity. We used McNemar’s chi-square test to compare validation measures between the revised version (3.0) and the 2.0 version. Results Algorithmic changes made to B-RST™ 2.0 increased the sensitivity against BRCA1/2 mutation analysis from 71.1 to 94.0% (P < 0.0001). While specificity decreased, all screen-positive individuals were appropriate for cancer genetics referral, the primary purpose of the tool. Conclusion Despite calls for BRCA1/2 population screening, there remains a critical need to identify those most at risk who should receive cancer genetics services. B-RST™ version 3.0 demonstrates high sensitivity for BRCA1/2 mutations, yet remains a simple and quick screening tool for at-risk individuals.

    Constitutional epimutations are an alternative to genetic mutations in the etiology of genetic diseases. Some of these epimutations, termed secondary, correspond to the epigenetic effects of cis-acting genetic defects transmitted to the offspring following a Mendelian inheritance pattern. In Lynch syndrome, a few families with such apparently heritable MLH1 epimutations have been reported so far.

    Unexpected fetal abnormalities occur in 2–5% of pregnancies. While traditional cytogenetic and microarray approaches achieve diagnosis in around 40% of cases, lack of diagnosis in others impedes parental counseling, informed decision making, and pregnancy management. Postnatally exome sequencing yields high diagnostic rates, but relies on careful phenotyping to interpret genotype results. Here we used a multidisciplinary approach to explore the utility of rapid fetal exome sequencing for prenatal diagnosis using skeletal dysplasias as an exemplar.

    Genet. Med. (IF 8.229) Pub Date : 2018-03-22
    Fabio Girardi, Daniel R Barnes, Daniel Barrowdale, Debra Frost, Angela F Brady, Claire Miller, Alex Henderson, Alan Donaldson, Alex Murray, Carole Brewer, Caroline Pottinger, D Gareth Evans, Diana Eccles, EMBRACE, Fiona Lalloo, Helen Gregory, Jackie Cook, Jacqueline Eason, Julian Adlard, Julian Barwell, Kai Ren Ong, Lisa Walker, Louise Izatt, Lucy E Side, M John Kennedy, Marc Tischkowitz, Mark T Rogers, Mary E Porteous, Patrick J Morrison, Ros Eeles, Rosemarie Davidson, Katie Snape, Douglas F Easton, Antonis C Antoniou

    BRCA1/BRCA2 predictive test negatives are proven noncarriers of a BRCA1/BRCA2 mutation that is carried by their relatives. The risk of developing breast cancer (BC) or epithelial ovarian cancer (EOC) in these women is uncertain. The study aimed to estimate risks of invasive BC and EOC in a large cohort of BRCA1/BRCA2 predictive test negatives.

  • Patterns of homozygosity in patients with uniparental disomy: detection rate and suggested reporting thresholds for SNP microarrays
    Genet. Med. (IF 8.229) Pub Date : 2018-03-22
    Nicole Hoppman, Kandelaria Rumilla, Emily Lauer, Hutton Kearney, Erik Thorland

    Single-nucleotide polymorphism (SNP) microarrays can easily identify whole-chromosome isodisomy but are unable to detect whole-chromosome heterodisomy. However, most cases of uniparental disomy (UPD) involve combinations of heterodisomy and isodisomy, visualized on SNP microarrays as long continuous stretches of homozygosity (LCSH). LCSH raise suspicion for, but are not diagnostic of, UPD, and reporting necessitates confirmatory testing. The goal of this study was to define optimal LCSH reporting standards.

  • A point mutation in the pre-ZRS disrupts sonic hedgehog expression in the limb bud and results in triphalangeal thumb–polysyndactyly syndrome

    The zone of polarizing activity regulatory sequence (ZRS) is an enhancer that regulates sonic hedgehog during embryonic limb development. Recently, mutations in a noncoding evolutionary conserved sequence 500 bp upstream of the ZRS, termed the pre-ZRS (pZRS), have been associated with polydactyly in dogs and humans. Here, we report the first case of triphalangeal thumb–polysyndactyly syndrome (TPT-PS) to be associated with mutations in this region and show via mouse enhancer assays how this mutation leads to ectopic expression throughout the developing limb bud.

    Congenital central hypoventilation syndrome (CCHS, OMIM 209880) is a rare autosomal dominant disorder caused by mutation in PHOX2B that manifests as a consequence of abnormal neural crest cell migration during embryogenesis. Unlike other neurocristopathies, however, its impact on the cardiovascular system has not been previously assessed. This study was an effort to characterize the association between congenital heart disease (CHD) and mutations in PHOX2B in patients with CCHS.

    Early treatment is critical for mucopolysaccharidosis type I (MPS I), justifying its incorporation into newborn screening. Enzyme replacement therapy (ERT) treats MPS I, yet presumptions that ERT cannot penetrate the blood–brain barrier (BBB) support recommendations that hematopoietic cell transplantation (HCT) treat the severe, neurodegenerative form (Hurler syndrome). Ethics precludes randomized comparison of ERT with HCT, but insight into this comparison is presented with an international cohort of patients with Hurler syndrome who received long-term ERT from a young age.
