One4Two ®: An Integrated Molecular Approach to Optimize Infertile Couples' Journey. Genes (Basel) 2021; 12:genes12010060. [PMID: 33401665 PMCID: PMC7824287 DOI: 10.3390/genes12010060] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 12/15/2020] [Accepted: 12/18/2020] [Indexed: 12/17/2022] Open
Abstract
The current diagnostic path of infertile couples is long lasting and often ineffective. Genetic tests, in particular, appear as a limiting step due to their jeopardized use on one side, and to the limited number of genes evaluated on the other. In this context, the development and diffusion, also in routine diagnostic settings, of next generation sequencing (NGS)-based methods for the analyses of several genes in multiple subjects at a time is improving the diagnostic sensitivity of molecular analyses. Thus, we developed One4Two®, a custom NGS panel to optimize the diagnostic journey of infertile couples. The panel validation was carried out in three steps analyzing a total of 83 subjects. Interestingly, all the previously identified variants were confirmed, assessing the analytic sensitivity of the method. Moreover, additional pathogenic variants have been identified underlying the diagnostic efficacy of the proposed method. One4Two® allows the simultaneous analysis of infertility-related genes, disease-genes of common inherited diseases, and of polymorphisms related to therapy outcome. Thus, One4Two® is able to improve the diagnostic journey of infertile couples by simplifying the whole process not only for patients, but also for laboratories and reproduction specialists moving toward an even more personalized medicine.

Diagnostics (Basel) 2019; 10:diagnostics10010007. [PMID: 31877800 PMCID: PMC7168058 DOI: 10.3390/diagnostics10010007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Revised: 12/16/2019] [Accepted: 12/19/2019] [Indexed: 12/15/2022] Open
Abstract
Because of the progression of genetics and genomics, the demand for prenatal diagnosis (PD) for inherited genetic diseases has increased. However, several incidental findings may emerge during PD, like misattributed paternity, the evidence of disease in a parent, and the possible misinterpretation of the results because of complex alleles or de novo mutations that have several implications. In a retrospective observational study on all the couples referred to our Medical School (1993–2018) for PD of genetic inherited diseases (n = 1502), we selected the cases of PD for cystic fibrosis (CF, n = 239) and hemophilia A and B (HA, HB, n = 47), revising all incidental findings previously mentioned. We found one case in which a technical error led to PD of carrier in two siblings that were born affected by CF, four cases of misattributed paternity, eight cases of asymptomatic parents revealed as affected by CF transmembrane regulator (CFTR)-related disorders, a case of a novel complex allele that could have caused the diagnosis of CF in a carrier fetus, and a case of a de novo mutation in a mother (already a carrier) that caused hemophilia in a child that PD had revealed as healthy. We present these conditions as clinical cases and discuss the technical, clinical, ethical, and legal aspects to be considered.

Abstract
PURPOSE We aimed to assess the clinical value of prenatal testing for cystic fibrosis (CF) and whether ethical considerations would affect endpoint selection. METHODS To determine effectiveness, we conducted a systematic literature review whose protocol outlined search strategies across eight databases, study inclusion criteria, and prespecified literature screening, data extraction, and synthesis processes. We conducted a scoping search on ethical considerations. RESULTS The genetic test showed good diagnostic performance. A change in clinical management was observed: termination of pregnancy (TOP) occurred in most cases where two pathogenic variants were identified in a fetus of carrier parents (158/167; 94.6%). The TOP rate was lower in pregnancies where CF was diagnosed after fetal echogenic bowel detection (~65%). TOP and caring for a child with CF were both associated with poor short-term parental psychological outcomes. Ethical analyses indicated that informed decisions should have been the main endpoint, rather than CF-affected births prevented. CONCLUSION CF testing leads to fewer CF-affected births. It is difficult to assess whether this means the test is valuable, since patients may not value TOP primarily in terms of maternal or fetal health outcomes, psychological or otherwise. The value of testing should arguably be measured in terms of improving patient autonomy rather than health.

Abstract
Infertility is considered a major public health issue, and approximately 1 out of 6 people worldwide suffer from infertility during their reproductive lifespans. Thanks to technological advances, genetic tests are becoming increasingly relevant in reproductive medicine. More genetic tests are required to identify the cause of male and/or female infertility, identify carriers of inherited diseases and plan antenatal testing. Furthermore, genetic tests provide direction toward the most appropriate assisted reproductive techniques. Nevertheless, the use of molecular analysis in this field is still fragmented and cumbersome. The aim of this review is to highlight the conditions in which a genetic evaluation (counselling and testing) plays a role in improving the reproductive outcomes of infertile couples. We conducted a review of the literature, and starting from the observation of specific signs and symptoms, we describe the available molecular tests. To conceive a child, both partners' reproductive systems need to function in a precisely choreographed manner. Hence to treat infertility, it is key to assess both partners. Our results highlight the increasing importance of molecular testing in reproductive medicine.

Abstract
BACKGROUND Many European laboratories offer molecular genetic analysis of the CFTR gene using a wide range of methods to identify mutations causative of cystic fibrosis (CF) and CFTR-related disorders (CFTR-RDs). Next-generation sequencing (NGS) strategies are widely used in diagnostic practice, and CE marking is now required for most in vitro diagnostic (IVD) tests in Europe. The aim of this multicenter study, which involved three European laboratories specialized in CF molecular analysis, was to evaluate the performance of Multiplicom's CFTR MASTR Dx kit to obtain CE-IVD certification. METHODS A total of 164 samples, previously analyzed with well-established "reference" methods for the molecular diagnosis of the CFTR gene, were selected and re-sequenced using the Illumina MiSeq benchtop NGS platform. Sequencing data were analyzed using two different bioinformatic pipelines. Annotated variants were then compared to the previously obtained reference data. RESULTS AND CONCLUSIONS The analytical sensitivity, specificity and accuracy rates of the Multiplicom CFTR MASTR assay exceeded 99%. Because different types of CFTR mutations can be detected in a single workflow, the CFTR MASTR assay simplifies the overall process and is consequently well suited for routine diagnostics.

Abstract
Cystic fibrosis (CF) is considered one of the most commonly occurring fatal genetic disorders. This disorder is associated with pancreatic insufficiency and pulmonary complications. However, at birth the initial complications are associated with bowel obstruction. Cystic fibrosis management warrants an interdisciplinary team because this disorder affects various organ systems. Effective management of the newborn with CF assists in improving the child's overall prognosis. Family support is critical throughout the prenatal and postnatal periods. The case presented reviews a child born with suspected CF and the clinical course within the NICU.

Abstract
BACKGROUND The development of technologies that detect monogenic diseases in embryonic and fetal samples are opening novel diagnostic possibilities for preimplantation genetic diagnosis (PGD) and prenatal diagnosis (PND) thereby changing laboratory practice. Molecular diagnostic laboratories use different workflows for PND depending on the disease, type of biological sample, the presence of one or more known mutations, and the availability of the proband. Paternity verification and contamination analysis are also performed. The aim of this study was to test the efficacy of a single workflow designed to optimize the molecular diagnosis of monogenic disease in families at-risk of transmitting a genetic alteration. METHODS We used this strategy, which we designated "SEeMORE strategy" (Single-tube Electrophoresis analysis-based genotyping to detect MOnogenic diseases Rapidly and Effectively from conception to birth). It consists of a multiplex PCR that simultaneously carries out linkage analysis, direct analysis, maternal contamination and parenthood testing. We analyzed samples from previously diagnosed families for PND (cystic fibrosis or Duchenne muscular dystrophy) without, however, knowing the results. RESULTS The results obtained with the SEeMORE strategy concurred with those obtained with traditional PND. In addition, this strategy has several advantages: (i) use of one or a few cells; (ii) reduction of the procedure to 1 day; and (iii) a reduction of at least 2-3-fold of the analytic cost. CONCLUSIONS The SEeMORE strategy is effective for the molecular diagnosis of monogenic diseases, irrespective of the amount of starting material and of the disease mutation, and can be used for PND and PGD.

Abstract
Inherited liver diseases are a group of metabolic and genetic defects that typically cause early chronic liver involvement. Most are due to a defect of an enzyme/transport protein that alters a metabolic pathway and exerts a pathogenic role mainly in the liver. The prevalence is variable, but most are rare pathologies. We review the pathophysiology of such diseases and the diagnostic contribution of laboratory tests, focusing on the role of molecular genetics. In fact, thanks to recent advances in genetics, molecular analysis permits early and specific diagnosis for most disorders and helps to reduce the invasive approach of liver biopsy.

Abstract
Liver inherited diseases are a group of genetically determined clinical entities that appear with an early chronic liver involvement. They include Wilson's disease (hepatolenticular degeneration), hereditary hemochromatosis, and alpha-1-antitrypsin deficiency. In addition, cystic fibrosis, although it is not specifically a liver disease, may cause a severe liver involvement in a significant percentage of cases. For all these pathologies, the disease gene is known, and molecular analysis may contribute to the unequivocal diagnosis. This approach could avoid the patient invasive procedures and limit complications associated with a delay in diagnosis. We review liver inherited diseases on the basis of the genetic defect, focusing on the contribution of molecular analysis in the multistep diagnostic workup.
