Abstract
In this cross-sectional study, we assessed the attitudes of the general public in Saudi Arabia regarding both medical and non-medical applications of pre-implantation genetic diagnosis (PGD). The study was conducted in King Abdullah Specialist Children's Hospital (KASCH) in Riyadh with a sample size of 377. Demographic information was collected, and attitudes towards applications of PGD were assessed using a pre-validated self-administered questionnaire. Out of the total sample size, 230 (61%) were males, 258 (68%) were married, 235 (63%) had one child or more, and 255 (68%) were older than 30 years of age representing the majority of participants. Only 87 (23%) of participants reported prior experience with PGD. Personally, knowing someone who had a prior experience with PGD was associated with higher attitude scores (more favorable attitudes towards PGD) (p-value = 0.04). The findings of this study indicate that our sample of Saudi individuals generally had a positive attitude towards the use of PGD.

Abstract
Background: Deleterious mutations in the human gene phenylalanine hydroxylase (PAH) encoding the phenylalanine hydroxylase enzyme give rise to classic phenylketonuria and hyperphenylalaninemia. Our study was designed to characterize the spectrum of variants in the PAH gene in Saudi patients. Materials and Methods: We screened a cohort of 72 Saudi patients with clinical and biochemical diagnoses of hyperphenylalaninemia at the largest tertiary care center in Saudi Arabia; the King Faisal Specialist Hospital and Research Center (KFSH&RC), Riyadh. All patient's charts were reviewed under an approved study by Institutional Review Board. Results: Twenty-one different PAH variants were identified among the 144 PAH alleles assessed by targeted gene sequencing. Within the studied cohort, 60 of 72 patients had homozygous mutations with the the remaining 12 being compound heterozygotes. The most prevalent of the disease alleles identified in this study was the p.(Arg252Trp) mutation, which accounted for 38 of 144 alleles (26.4%). With the high incidence of genetic disorders in the population, religiously permissible preventive reproductive measures are a priority in our practice. Prenatal diagnoses carried out on four fetuses revealed two that were homozygous for PAH pathogenic variants. In addition, pre-implantation genetic diagnoses were initiated for 19 families. Eight of these families completed more than one full cycle of treatment, from which one healthy newborn was delivered. Conclusions: This study describes the spectrum of PAH variants in the Saudi population and highlights the molecular heterogeneity underlying phenylketonuria and hyperphenylalaninemia. These results add to the existing knowledge about PAH variants in Middle Eastern Countries. These results can be further translated to provide: informed counseling; cascade carrier testing in extended family members; and pre-marital screening.

The Special Features of Prenatal and Preimplantation Genetic Counseling in Arab Countries. Genes (Basel) 2022; 13:genes13020167. [PMID: 35205212 PMCID: PMC8872395 DOI: 10.3390/genes13020167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2021] [Revised: 01/02/2022] [Accepted: 01/12/2022] [Indexed: 12/04/2022] Open
Abstract
Genetic counseling services have only recently been introduced in most Arab countries, and their utilization is increasing. Prenatal genetic counseling is essential, particularly in the Arab context, which is characterized by high rates of consanguinity. Nevertheless, little is known about the decisions faced by parents and the factors underlying the complex decision making that must occur when accessing these services in Arab countries. Herein, we performed a narrative review to discuss the reported experiences of parents accessing genetic counseling in the prenatal setting in the 22 Arab countries. We also highlight the different types of decisions encountered and the factors influencing them. We report that: (i) utilization of genetic counseling services varies across different Arab countries; (ii) many factors affect decision making and service utilization, especially religion; and (iii) parents are faced with an array of decisions in the prenatal setting, partly driven by increased utilization of prenatal diagnosis and preimplantation genetic testing in some countries. Our work is the first to highlight the different factors and decisions influencing genetic counseling in Arab countries. Understanding these factors is essential for improving genetic counseling services in the region and helping counselors facilitate informed decision making.

Abstract
Background: Chromosomal abnormalities affect many children which lead to high rates of morbidity and mortality among them. So, preimplantation genetic testing (PGT) is an evolving technology used to detect a specific genetic disorder in embryos of a couple known to be carriers or affected by a specific mutation. Similarly, it could be used in advanced maternal age which is a high risk of chromosomal abnormalities. Although PGT is a solution for many inherited chromosomal disorders, many ethical dilemmas surround its application. Thus, the aim of this study is to evaluate the community awareness and acceptance of PGT which will eventually lead to a healthier society through disease-free babies in Eastern Province, Kingdom of Saudi Arabia (KSA). Methodology: A qualitative cross-sectional questionnaire-based study was conducted within the population of the Eastern Province of Saudi Arabia. The questionnaire was designed in Arabic and distributed electronically through social media platforms. Results: The study included 837 participants, whose ages ranged from 18 to 65 years with the mean age 33.5 ± 11.9 years. Good awareness and acceptance were detected among 53.7% of the old aged group (50 years or more) compared to 39.5% of the young age group. Also, 44.9% of female participants had good awareness in comparison to 34.2% of males (p=.033). Participants with a higher number of children had significantly higher awareness and acceptance of PGT. Also, 44.3% of participants who knew someone in need of assisted reproductive technology, had good awareness and acceptance levels compared to 36.9% of those who did not (p=.033). Conclusion: The perception of Eastern Province’s Saudi citizens toward PGT is found to be low. Increasing their perception toward such technology is needed as it is known that many chromosomal abnormalities are prevalent among this population, particularly sickle cell disease. Achieving this goal will eventually lead to decrease the burden of prevalent inherited diseases. Since Saudis' opinions are almost influenced by cultural and religious points of view, care should be given to these aspects.

Abstract
This study examined perspectives on the ethical implications of preimplantation genetic testing (PGT) among individuals who actually (not hypothetically) used or considered using PGT. Most of the prior patient-centered research on PGT ethics used qualitative designs (9 out of the 11 articles) and focused only on single gene testing. This cross-sectional study used an anonymous online questionnaire; 15 items assessed potential ethical concerns involved in PGT decision-making, including clinical indications for PGT, the greater implications of PGT for society, and unused embryo disposition. N = 207 individuals (mean female/male age 35.7/38.9 years, 21% Hispanic or non-White) who had recently used or considered using PGT for single gene (60%) or for chromosomal testing (40%) completed the questionnaire. Most respondents supported PGT screening for disease conditions with childhood or adult onset that are untreatable (64%-85% across items); most opposed PGT for trait selection (76%-81%). Most respondents agreed that PGT aids in parental decision-making (66%-67%), although some expressed concern over potential unforeseen consequences (25%-30%). Regarding disposition of embryos without known genetic abnormalities, most respondents favored freezing indefinitely (86%) or donating to another family (69%), while for embryos with genetic abnormalities, most respondents favored donating to research (78%) or destroying them (62%). Stratification by religious affiliation revealed several differences, such as less acceptance of PGT for diseases that occur in adulthood and have no treatment options among Protestants (p = .015) and greater willingness to donate surplus embryos to research among participants without a religious affiliation (p < .001). These results are limited by the relatively homogeneous sample of participants (mostly White, married, and predominantly college-educated). In summary, participants who considered/used PGT found PGT acceptable overall for screening for disease conditions; most opposed using PGT for trait selection. Our novel questionnaire provides a structured tool for assessing the ethical perspectives surrounding the use of PGT.

Abstract
What are the ethical perspectives of preimplantation genetic testing in patients using/considering PGT-A compared to those using/considering PGT-M? A 17-item questionnaire administered online was used to assess ethical perspectives in US patients who recently used/considered PGT-A (n=80) vs. those who used/considered PGT-M (n=72). Kruskal-Wallis, Chi-square, and Fisher exact tests were conducted with STATA. Most PGT-A and PGT-M users/considerers supported using PGT to screen for diseases fatal in childhood (86-89%) and those causing lifelong disabilities (76-79%) and opposed using PGT to screen for non-medical physical (80-87%) or intellectual traits (74-86%). Both groups agreed that PGT aids in parental decision-making, although some expressed concern over its potential to lead to unforeseen consequences for society and the PGT offspring. More PGT-M than PGT-A users/considerers opposed implanting genetically abnormal embryos when requested by parents (29% PGT-A vs. 56% PGT-M, p = 0.007). For embryo disposition, more PGT-A users/considerers favored freezing (95% PGTA vs. 82% PGT-M, p = 0.018) or donating genetically normal embryos to research (73% PGT-A vs. 57% PGT-M, p = 0.044), while more PGT-M users/considerers supported donating embryos with known genetic abnormalities to research (56% PGT-A vs. 81% PGT-M, p = 0.001). Regardless of the reason for using PGT, users generally agreed on the acceptable and unacceptable uses for it, as well as the potential societal impact. PGT-M users/considerers expressed more opposition than PGT-A users/considerers to implanting embryos with a genetic alteration when requested by the parents.

A review on the motivations, decision-making factors, attitudes and experiences of couples using pre-implantation genetic testing for inherited conditions. Hum Reprod Update 2021; 27:944-966.

Abstract
BACKGROUND In pre-implantation genetic testing (PGT), fertile couples undergo IVF with genetic testing of embryos to avoid conceptions with a genetic condition. There is an exponentially increasing uptake with over 600 applications listed by the Human Fertilisation and Embryology Authority in the UK. The psychological aspects of the decision-making process and the experience of PGT, however, are relatively underevaluated, with the potential to leave patients unsupported in their journeys. OBJECTIVE AND RATIONALE In this review, we aim to comprehensively report on every aspect of couples' experiences of PGT. We consider what motivates users, the practical and ethical decisions involved and how couples navigate the decision-making process. Additionally, we report on the social and psychological impact on couples who are actively undergoing or have completed the PGT process. SEARCH METHODS A systematic search of English peer-reviewed journals of three computerized databases was undertaken following PRISMA guidelines. Studies that examined the motivations, attitudes, decision-making factors and experiences of patients who have been actively engaged in the PGT process were included. No restrictions were placed on study design or date of publication. Studies examining patients using PGT in a hypothetical context or solely using PGT for aneuploidy were excluded. Qualitative data were extracted using thematic analysis. OUTCOMES The main outcomes were patient motivations, deciding factors and attitudes, as well as the patient experience of coming to a decision and going through PGT.Patients were primarily motivated by the desire to have a healthy child and to avoid termination of pregnancy. Those with a sick child or previous experience of termination were more likely to use PGT. Patients also felt compelled to make use of the technology available, either from a moral responsibility to do so or to avoid feelings of guilt if not. The main factors considered when deciding to use PGT were the need for IVF and the acceptability of the technology, the financial cost of the procedure and one's ethical standpoint on the creation and manipulation of embryos. There was a general consensus that PGT should be applied to lethal or severe childhood disease but less agreement on use for adult onset or variable expression conditions. There was an agreement that it should not be used to select for aesthetic traits and a frustration with the views of PGT in society. We report that couples find it difficult to consider all of the benefits and costs of PGT, resulting in ambivalence and prolonged indecision. After deciding on PGT use, we found that patients find the process extremely impractical and psychologically demanding. WIDER IMPLICATIONS This review aimed to summarize the current knowledge on how patients decide to use and experience PGT and to make suggestions to incorporate the findings into clinical practice. We cannot stress enough the importance of holistic evaluation of patients and thorough counselling prior to and during PGT use from a multidisciplinary team that includes geneticists, IVF clinicians, psychologists and also patient support groups. Large prospective studies using a validated psychological tool at various stages of the PGT process would provide an invaluable database for professionals to better aid patients in their decision-making and to improve the patient experience.

Abstract
Preimplantation genetic testing (PGT) is an alternative reproductive technology integrated with in vitro fertilization (IVF). It is a well-established technique offering a reproductive option for families at a high risk of transmitting a genetic disorder, allowing them to avoid making a decision about termination of an affected pregnancy (TOP). In Arab communities and particularly in Oman, where TOP is not favored under the majority of implemented Muslim law, termination of pregnancy for fetal indications is not always possible. As these communities are in favor of consanguineous marriage, they are at increased risk of serious and lethal autosomal recessive conditions, and as a result, PGT is a feasible option as a TOP decision can be avoided. However, undergoing PGT is relatively new in the Arab Muslim countries and Omani patients have only recently had access to the service. This qualitative study utilized a phenomenological approach to explore the experience of Omani families who had selected to undergo PGT as a means of reducing the risk of having a child affected with a genetic disorder. Fourteen participants from eight families who underwent PGT were interviewed. Data collected were analyzed using thematic analysis. The research identified four main themes: Anxiously waiting 'Taraqub'; Unforeseen; Secrecy; and Me and My Partner. The findings of the research have provided insight into the PGT experiences of Omani families. Unique cultural and religious perspectives should be considered when counseling Omani Muslim couples.

Abstract
OBJECTIVE To analyze psychometric properties of two novel instruments assessing decisional distress and uncertainty experienced by individuals considering preimplantation genetic testing (PGT). METHODS The new PGT Decisional Distress instrument (22 items) assesses negative/positive emotions. The new PGT Decisional Uncertainty instrument assesses Clarity about test benefits/disadvantages (5 items) and Certainty of having adequate information/support to make a good decision (7 items). Scales ranged from 0 to 4. Psychometrics (central tendencies, internal consistency reliability, and discriminant validity) were evaluated. Stratified analysis by decision stage was conducted. All participants had considered or used PGT in the previous 6 months. RESULTS N = 106 females (mean age 36.5 ± 4.8 years; 16% non-Caucasian; 9% Hispanic) across 16 US states completed an online anonymous questionnaire. On average, respondents reported minimal distress (mean 0.96), high clarity (mean 3.26), and high certainty (mean 3.06), particularly those who had already decided compared to undecided women (P ≤ .02). Instruments had excellent internal consistency (Cronbach's α's 0.92-0.94) and displayed sufficient inter-individual variability (SD's 0.75-0.89). Correlations confirmed expected patterns of association between instruments (P's < .01), indicating discriminant validity. CONCLUSION We document initial reliability and validity of new instruments to measure emotional distress and uncertainty in female patients who have recently considered PGT for single-gene or chromosomal disorders.

Abstract
There has been considerable recent progress in the implementation of public health genomics policy throughout the developed world. However, in the developing world, genetic services still remain limited, or unavailable to most. Here, we discuss challenges and opportunities related to the implementation of public health genomics in developing countries. We focus on Pakistan, a country with one of the world's highest rates of inter-family marriages and prevalence of inherited genetic conditions. Pakistan still lacks a national newborn screening programme, clinical genetic testing services, or public health genomics framework. The medical infrastructure in Pakistan, characterized by limited publicly-funded health services and a significant burden of infectious disease, may contribute to de-prioritization of genetic health services. In addition, there are a number of societal, cultural and religious factors to consider. Recently a number of large research studies have been conducted in populations of Pakistani descent, mostly in collaboration with major US, UK and European institutions. Some of these have yielded high-impact scientific findings, but have yet to translate into public health outcomes in Pakistan. Before the benefits of genomics can be realized in developing countries, the first initial steps towards strategic prioritization, resourcing, and long-term goal setting are required. We propose some practical recommendations and possible first steps forward.

The increasing technical complexity and evolving options for repro-genetic testing have direct implications for information processing and decision making, yet the research among patients considering preimplantation genetic diagnosis (PGD) is narrowly focused. This review synthesizes the literature regarding patient PGD decision-making factors, and illuminates gaps for future research and clinical translation. Twenty-five articles met the inclusion criteria for evaluating experiences and attitudes of patients directly involved in PGD as an intervention or considering using PGD. Thirteen reports were focused exclusively on a specific disease or condition. Five themes emerged: (1) patients motivated by prospects of a healthy, genetic-variant-free child, (2) PGD requires a commitment of time, money, energy and emotions, (3) patients concerned about logistics and ethics of discarding embryos, (4) some patients feel sense of responsibility to use available technologies, and (5) PGD decisions are complex for individuals and couples. Patient research on PGD decision-making processes has very infrequently used validated instruments, and the data collected through both quantitative and qualitative designs have been inconsistent. Future research for improving clinical counseling is needed to fill many gaps remaining in the literature regarding this decision-making process, and suggestions are offered.

Abstract
Hemoglobinopathies (HBP) are the most common genetic disorder in Oman and are in need of prevention programs due to the high incidence of β-thalassemia major and sickle cell disease. Prenatal diagnosis (PD) and selective pregnancy termination is shown to be the most effective prevention tool for the control of HBP. However, PD is not available in Oman thus far because abortion is subject to religious, cultural and ethical issues. We have examined the attitude of a number of Omani HBP carrier couples towards prenatal diagnosis and selective abortion. We have interviewed 35 couples at risk visiting the main premarital clinic in Muscat between Jan 2011 and Jan 2012. Couples were interviewed using a pre-structured questionnaire. The majority would have accepted prenatal diagnosis (94%) if the service would be available in the country but pregnancy termination was greatly influenced by religious values.

Abstract
Haemoglobinopathies including the thalassemias and sickle cell disease are known to be prevalent inherited disorders in most Arab countries with varying prevalence rates and molecular characterisation. β-thalassemia is encountered in polymorphic frequencies in almost all Arab countries with carrier rates of 1-11 % and a varying number of mutations. The most widespread mutation in Lebanon, Egypt, Syria, Jordan, Tunisia and Algeria is the IVS-I-110 (G>A). In the Eastern Arabian Peninsula, the Asian Indian mutations (IVS-I-5 (G>C), codons 8/9 (+G) and IVS-I (-25 bp del)) are more common. The α-thalassemias are encountered in the majority of Arab countries in frequencies ranging from 1 to 58 % with the highest frequencies reported from Gulf countries. The (-α(3.7)) mutation is the most frequent followed by the non-deletional α2 polyadenylation signal mutation (AATAAA>AATAAG) and the α2 IVS1 5-bp deletion. The rates of sickle cell trait in Arab countries range from 0.3 to 30 %, with the Benin, the Arab-Indian and the Bantu haplotypes constituting the bulk of the haplotypes, leading to two major phenotypes; a mild one associated with the Arab-Indian and a severe one with the Benin and Bantu haplotypes. Public health approaches targeting prevention of haemoglobinopathies in Arab countries include newborn screening for sickle cell disease, and premarital screening for carriers of β-thalassemia and sickle cell disease. These services are still patchy and inadequate in many Arab countries recommending the upgrade of these services with strengthening of the education and training of health care providers and raising public awareness on the feasibility of prevention and care for haemoglobinopathies.
