Abstract
The development in human genetics must be tracked with the knowledge to provide support and positive attitudes towards genetic research and its healthcare applications, including genetic testing. Unfortunately, there has been a delay in enacting public policies related to the genetics professionals as well as the diagnosis, treatment, and prevention of genetic diseases in Indonesia. This research was conducted to build an overview of genetic knowledge and public attitudes toward genetic testing among Indonesian undergraduates. This cross-sectional study involved undergraduate students selected using the convenience sampling method. The questionnaire consisted of two parts: a true/false questionnaire (16 statements) regarding knowledge of genetics and a 5-points Likert scale questionnaire (27 statements) pertaining to attitudes towards genetic testing. A total of 1596 undergraduate students completed online questionnaire. The highest knowledge score and the most positive overall attitudes were observed in the healthcare-related majors compared to those who studied science and technology and social and humanity. A weak positive correlation was observed between knowledge and attitude toward genetic testing (Pearson's r = 0.206, p < 0.001). Undergraduate students from healthcare-related majors displayed better in both knowledge of genetics and had more positive attitudes toward genetic testing.

Attitudes towards genetic testing: The role of genetic literacy, motivated cognition, and socio-demographic characteristics. PLoS One 2023; 18:e0293187. [PMID: 37967060 PMCID: PMC10651000 DOI: 10.1371/journal.pone.0293187] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 09/26/2023] [Indexed: 11/17/2023] Open
Abstract
Understanding reasons for why people choose to have or not to have a genetic test is essential given the ever-increasing use of genetic technologies in everyday life. The present study explored the multiple drivers of people's attitudes towards genetic testing. Using the International Genetic Literacy and Attitudes Survey (iGLAS), we collected data on: (1) willingness to undergo testing; (2) genetic literacy; (3) motivated cognition; and (4) demographic and cultural characteristics. The 37 variables were explored in the largest to-date sample of 4311 participants from diverse demographic and cultural backgrounds. The results showed that 82% of participants were willing to undergo genetic testing for improved treatment; and over 73%-for research. The 35 predictor variables together explained only a small proportion of variance: 7%-in the willingness to test for Treatment; and 6%-for Research. The strongest predictors of willingness to undergo genetic testing were genetic knowledge and deterministic beliefs. Concerns about data misuse and about finding out unwanted health-related information were weakly negatively associated with willingness to undergo genetic testing. We also found some differences in factors linked to attitudes towards genetic testing across the countries included in this study. Our study demonstrates that decision-making regarding genetic testing is influenced by a large number of potentially interacting factors. Further research into these factors may help consumers to make decisions regarding genetic testing that are right for their specific circumstances.

Abstract
With the increasing number of cancer cases worldwide, genetic testing for familiar cancers seems inevitable, yet little is known on population interest and the monetary value for cancer genetic risk information. The current study aimed to determine the willingness to undergo and pay for cancer genetic testing among the Malaysian population. A self-administered questionnaire was distributed to cancer patients and their family members in the oncology and daycare units in several government hospitals. Of 641 respondents (354 patients, 287 family members), 267 (41.7%) were willing to undergo cancer genetic testing. The median that respondents were willing to pay was USD 48.31 (MYR 200.00) IQR USD 96.91 (MYR 400), while 143 (22.3%) respondents were willing to pay a shared cost with the insurance company. Regression analysis identified independent positive predictors of willingness to pay as respondent's status as a family member, high education level, and willingness to undergo cancer genetic testing in general, while in patients, female gender and high level of education were identified as independent positive predictors. Generally, the population needs more information to undergo and pay for cancer genetic testing. This will increase the utilization of the services offered, and with cost-sharing practices with the provider, it can be implemented population-wide.

Abstract
The aim of this study is to assess attitudes towards genetic testing in Georgian public. We used a Likert-scale written questionnaire. The survey was completed by 480 respondents. A majority of respondents (75.3%) curious about predictive genetic testing and 40.6% of participants preferred to be tested only for disorders that are treatable or preventable. Approximately 65% of the participants would like to test their newborn children for late-onset disorders and undergo preconception carrier screening (73%). In addition, the majority (59%) of our respondents were not worried that genetic testing would further stigmatize people with disabilities. These results indicate that the respondents surveyed in our study may have placed particularly high importance on the availability of genetic testing and greatly valued access to genomic information.

Abstract
We live in an age of rapidly advancing genetic research. This research is generating new knowledge that has implications for personal health and well-being. The present study assessed the level of genetic knowledge and personal engagement with genetics in a large sample (N = 5404) of participants. Participants received secondary education in 78 countries, with the largest samples from Russia, the UK and the USA. The results showed significant group differences in genetic knowledge between different countries, professions, education levels and religious affiliations. Overall, genetic knowledge was poor. The questions were designed to assess basic genetic literacy. However, only 1.2% of participants answered all 18 questions correctly, and the average score was 65.5%. Genetic knowledge was related to peoples' attitudes towards genetics. For example, those with greater genetic knowledge were on average more willing to use genetic knowledge for their personal health management. Based on the results, the paper proposes a number of immediate steps that societies can implement to empower the public to benefit from ever-advancing genetic knowledge.

Abstract
In clinical practice and in research, there is an ongoing debate on how to return incidental and secondary findings of genetic tests to patients and research participants. Previous investigations have found that most of the people most of the time are in favor of full disclosure of results. Yet, the option to reject disclosure, based on the so-called right not to know, can be valuable especially for some vulnerable subgroups of recipients. In the present study we investigated variations in informational preferences in the context of genetic testing in a large and diverse German sample. This survey examined health care professionals, patients, participants of genetic counseling sessions and members of the general population (N = 518). Survey participants were assessed regarding their openness to learning about findings under various hypothetical scenarios, as well as their attitudes about the doctor-patient-relationship in a disclosure situation and about informational transfer to third parties. While the majority of participants wanted to learn about their findings, the extent of support of disclosure varied with features of the hypothetical diagnostic scenarios (e.g., controllability of disease; abstract vs. concrete scenario description) and demographic characteristics of the subjects. For example, subjects with higher levels of education were more selective with regards to the kind of information they want to receive than those with lower levels of education. We discuss implications of these findings for the debate about the right not to know and for the clinical practice of informed consent procedures.

Abstract
AIMS To explore the views of the Belgian public on various topics surrounding genetics and genetic testing (GT). MATERIALS AND METHODS A written questionnaire was administered to visitors of the annual cartoon festival in Knokke-Heist, Belgium, during the summer of 2014. The main theme of the festival was challenges and progress in human genetics and it was attended by more than 100,000 visitors. RESULTS The survey was completed by 1182 respondents, resulting in a demographically diverse sample with a mean age of 48.5 years. Our respondents expressed moderate interest in predictive GT, with 39.1% willing to learn about their predisposition to diseases through GT and 49.5% indicating interest in getting tested exclusively for treatable/preventable diseases. We observed higher interest in GT for reproductive purposes, such as preconception screening for recessive disorders (53.8%) and prenatal GT (60.7%). A substantial minority (46.4%) of the respondents were worried that GT could further stigmatize people with disabilities, while 39.7% believed that carrier screening for recessive diseases would lead to an inferior image of people affected by them. CONCLUSION Paying due attention to the attitudes, beliefs, and concerns of the general public is important to ensure ethically sound and socially acceptable implementation of new genetic technologies.

Abstract
Clinical deficiency of the B-vitamin riboflavin (vitamin B2) is largely confined to developing countries; however accumulating evidence indicates that suboptimal riboflavin status is a widespread problem across the developed world. Few international data are available on riboflavin status as measured by the functional biomarker, erythrocyte glutathione reductase activation coefficient, considered to be the gold standard index. One important role of riboflavin in the form of flavin dinucleotide is as a co-factor for the folate-metabolising enzyme methylenetetrahydrofolate reductase (MTHFR). Homozygosity for the common C677T polymorphism in MTHFR, affecting over 10 % of the UK and Irish populations and up to 32 % of other populations worldwide, has been associated with an increased risk of CVD, and more recently with hypertension. This review will explore available studies reporting riboflavin status worldwide, the interaction of riboflavin with the MTHFR C677T polymorphism and the potential role of riboflavin in personalised nutrition. Evidence is accumulating for a novel role of riboflavin as an important modulator of blood pressure (BP) specifically in individuals with the MTHFR 677TT genotype, with results from a number of recent randomised controlled trials demonstrating that riboflavin supplementation can significantly reduce systolic BP by 5-13 mmHg in these genetically at risk adults. Studies are however required to investigate the BP-lowering effect of riboflavin in different populations and in response to doses higher than 1·6 mg/d. Furthermore, work focusing on the translation of this research to health professionals and patients is also required.

Abstract
The notion of educating the public through generic healthy eating messages has pervaded dietary health promotion efforts over the years and continues to do so through various media, despite little evidence for any enduring impact upon eating behaviour. There is growing evidence, however, that tailored interventions such as those that could be delivered online can be effective in bringing about healthy dietary behaviour change. The present paper brings together evidence from qualitative and quantitative studies that have considered the public perspective of genomics, nutrigenomics and personalised nutrition, including those conducted as part of the EU-funded Food4Me project. Such studies have consistently indicated that although the public hold positive views about nutrigenomics and personalised nutrition, they have reservations about the service providers' ability to ensure the secure handling of health data. Technological innovation has driven the concept of personalised nutrition forward and now a further technological leap is required to ensure the privacy of online service delivery systems and to protect data gathered in the process of designing personalised nutrition therapies.

Abstract
BACKGROUND The pace of discoveries and advances in genomic research is not reflected in the pace of their translation and incorporation into day-to-day clinical medicine to individualize healthcare decision-making processes. One of the main obstacles is the poor understanding of the policies and the key stakeholders involved in these translation processes. METHODS We used the computerized version of the PolicyMaker political mapping tool to collect and organize important information about the pharmacogenomics and genomic medicine policy environment, serving as a database for assessments of the policy's content, the major players, their power and policy positions, their interests, and networks and coalitions that interconnect them. RESULTS AND CONCLUSIONS Our findings indicate that the genomic medicine policy environment in Greece seems to be rather positive, as the vast majority of the stakeholders express their medium to high support in the initially set goals of genomic medicine policy environment. The Ministry of Health and public healthcare insurance funds seem to oppose it, most likely due to financial constrains. These findings would contribute in selecting and implementing policy measures that will expedite the adoption of genomics into conventional medical interventions.

Abstract
Aim: In the postgenomic era, in many European countries, very little is known regarding the level of awareness of healthcare professionals with respect to pharmacogenomics and personalized medicine. Methods: Here, we report the findings of an in-depth study, involving 86 pharmacists and 208 physicians, to assess their level of awareness of pharmacogenomics and personalized medicine. Results: Our findings indicate that approximately 60% of pharmacists consider their level of knowledge of personalized medicine to be very low, while over half of the pharmacists and physicians intimate that they would be unable to explain the results of pharmacogenomic tests to their customers or patients, respectively. This situation may be directly related to the low level of their undergraduate education in genetics and pharmacogenomics. Conclusion: These findings provide the basis for assessing the views of healthcare professionals in relation to personalized medicine in Greece, and should help to facilitate the integration of genomics into the medical decision-making process.

Abstract
There is growing expectation that advances in genomics herald the age of personalized medicine. Medicine has always been personal; however, the growing availability of genomic tools and technologies enable more precise risk stratification and disease management than ever before. Notably, a key aspect of the success of personalized medicine is related to public acceptance and engagement. For example, the public must be willing to collect and utilize family history and other genomic information, and individuals must be able to interpret and comprehend the significance of genomic information for their health and well-being. In this article, we review public engagement initiatives with personalized medicine, outline some of the challenges to engaging the public with personalized and genomic medicine and offer suggestions for future engagement initiatives. As genomic advances continue, the need for public input in the development of appropriate institutional practices and public policy about personalized medicine is ever important.

Genomic medicine seeks to exploit an individual’s genomic information in the context of guiding the clinical decision-making process. In the post-genomic era, a range of novel molecular genetic testing methodologies have emerged, allowing the genetic testing industry to grow at a very rapid pace. As a consequence, a considerable number of different private diagnostic testing laboratories now provide a wide variety of genetic testing services, often employing a direct-to-consumer (DTC) business model to identify mutations underlying (or associated with) common Mendelian disorders, to individualize drug response, to attempt to determine an individual’s risk of a multitude of complex (multifactorial) diseases, or even to determine a person’s identity. Recently, we have noted a novel trend in the provision of private molecular genetic testing services, namely saliva and buccal swab collection kits (for deoxyribonucleic acid (DNA) isolation) being offered for sale over the counter by pharmacies. This situation is somewhat different from the standard DTC genetic testing model, since pharmacists are healthcare professionals who are supposedly qualified to give appropriate advice to their clients. There are, however, a number of issues to be addressed in relation to the marketing of DNA collection kits for genetic testing through pharmacies, namely a requirement for regulatory clearance, the comparative lack of appropriate genetics education of the healthcare professionals involved, and most importantly, the lack of awareness on the part of both the patients and the general public with respect to the potential benefits or otherwise of the various types of genetic test offered, which may result in confusion as to which test could be beneficial in their own particular case. We believe that some form of genetic counseling should ideally be integrated into, and made inseparable from, the genetic testing process, while pharmacists should be obliged to receive some basic training about the genetic tests that they offer for sale.

Abstract
It is predicted that non-communicable diseases will account for over 73 % of global mortality in 2020. Given that the majority of these deaths occur in developed countries such as the UK, and that up to 80 % of chronic disease could be prevented through improvements in diet and lifestyle, it is imperative that dietary guidelines and disease prevention strategies are reviewed in order to improve their efficacy. Since the completion of the human genome project our understanding of complex interactions between environmental factors such as diet and genes has progressed considerably, as has the potential to individualise diets using dietary, phenotypic and genotypic data. Thus, there is an ambition for dietary interventions to move away from population-based guidance towards 'personalised nutrition'. The present paper reviews current evidence for the public acceptance of genetic testing and personalised nutrition in disease prevention. Health and clear consumer benefits have been identified as key motivators in the uptake of genetic testing, with individuals reporting personal experience of disease, such as those with specific symptoms, being more willing to undergo genetic testing for the purpose of personalised nutrition. This greater perceived susceptibility to disease may also improve motivation to change behaviour which is a key barrier in the success of any nutrition intervention. Several consumer concerns have been identified in the literature which should be addressed before the introduction of a nutrigenomic-based personalised nutrition service. Future research should focus on the efficacy and implementation of nutrigenomic-based personalised nutrition.

Public attitudes towards genetic testing revisited: comparing opinions between 2002 and 2010. Eur J Hum Genet 2012; 21:793-9. [PMID: 23249955 DOI: 10.1038/ejhg.2012.271] [Citation(s) in RCA: 81] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2012] [Revised: 10/10/2012] [Accepted: 11/13/2012] [Indexed: 01/30/2023] Open
Abstract
Ten years after the Human Genome Project, medicine is still waiting for many of the promised benefits, and experts have tempered their high expectations. Public opinion on genetic testing has generally been favourable but is this still the case? The aim of this study is to compare public experiences, beliefs and expectations concerning genetic testing over the years (2002 vs 2010). A cross-sectional questionnaire survey was conducted using the Dutch Health Care Consumer Panel in 2002 and 2010. Responses to questions in identical wording were compared. In 2002 and 2010, 817 (63%) and 978 (70%) members responded, respectively. Awareness and reported use of genetic tests remained stable over time. In 2010, more respondents expected genetic testing to become more widely applied, believed that knowledge about the genetic background of disease helps people live longer, and that testing should be promoted more intensively. In 2010, they were also more interested in their own genetic make-up. On the one hand, the concern that a dichotomy would emerge between people with 'good genes' and 'bad genes' was higher. On the other hand, respondents thought that insurance companies would be less likely to demand a genetic test in order to calculate health insurance premiums. In conclusion, the results suggest that in 8 years, expectations of benefits and potential use of genetic testing have been raised among the public, resulting in more positive opinions. Worries on inequity remain, although worries about premium differentiation by insurance companies have decreased.

Abstract
Misconceptions about genetics and genomics, such as notions of genetic determinism and the existence of ‘genes for’ particular traits, are widespread both in educational contexts and in the public perception of genetics and genomics. Owing to such misunderstandings, the prospect of personalized medicine often raises concerns with the general public about possible adverse societal consequences of the technologies that are implemented. Among the questions that are to be addressed in this context are: to what extent is personalized medical treatment possible? Does it require access to sensitive personal data? Who should be given such access? What other ethical issues might be raised by personalized medicine? How could these be answered? We argue that scientists have a professional responsibility to effectively communicate current knowledge and views about potential applications to the public in order to better address and resolve such issues.

Abstract
AIM The aim of this study was to understand the general public's and healthcare professionals' views on nutrigenomics. PATIENTS & METHODS We designed a cross-sectional survey of healthcare professionals (n = 87) and the general public (n = 1504) in the three largest cities in Greece (Athens, Thessaloniki and Patras). RESULTS Our data revealed that only 11.5% of respondents from the general public had been advised to take a genetic test in order to explore the relationship between their genes and their nutritional status. Although 80.5% of healthcare professionals would have been willing to recommend their patients/clients to undergo nutrigenomic analysis to correlate their genetic profile with their diet, only 17.2% of respondents had actually done so. In general, the general public was opposed to direct-access nutrigenomics testing. CONCLUSION The application of genomic information in the context of nutritional choice requires the continuing education of healthcare professionals and the dissemination of accurate and reliable information to the general public.

Abstract
AIM Progress in deciphering the functionality of the human genome sequence in the wake of technological advances in the field of genomic medicine have dramatically reduced the overall costs of genetic analysis, thereby facilitating the incorporation of genetic testing services into mainstream clinical practice. Although Greek genetic testing laboratories offer a variety of different genetic tests, relatively little is known about how either the general public or medical practitioners perceive genetic testing services. MATERIALS & METHODS We have therefore performed a nationwide survey of the views of 1717 members of the general public, divided into three age groups, from all over Greece, and residing in both large and small cities and villages, in order to acquire a better understanding of how they perceive genetic testing. We also canvassed the opinions of 496 medical practitioners with regard to genetic testing services in a separate survey that addressed similar issues. RESULTS Our subsequent analysis indicated that a large proportion of the general public is aware of the nature of DNA, genetic disorders and the potential benefits of genetic testing, although this proportion declines steadily with age. Furthermore, a large proportion of the interviewed individuals would be willing to undergo genetic testing even if the cost of analysis was not covered by healthcare insurance. However, a relatively small proportion of the general public has actually been advized to undergo genetic testing, either by relatives or physicians. Most physicians believe that the regulatory and legal framework that governs genetic testing services in Greece is rather weak. Interestingly, the vast majority of the general public strongly opposes direct-access genetic testing, and most would prefer referral from a physician than from a pharmacist. CONCLUSION Overall, our results provide a critical evaluation of the views of the general public with regard to genetics and genetic testing services in Greece and should serve as a model for replication in other populations.

Abstract
The concept of syntropic diseases was proposed at the beginning of the last century to emphasize the phenomenon of nonrandom co-occurrence of human disorders. Common genes underlying specific syntropic diseases were called syntropic genes. The application of this concept to contemporary genomic studies will facilitate the understanding of the molecular basis of complex diseases, provide future direction for discovering new targets for therapy and prognosis, and may even lead to the reassessment of disease classification for the practice of more precise personalized medicine. With the acceptance of the syntropic genes theory, new genetic tests, focused on markers pointing to a set of pathogenetically linked diseases rather than to a single nosology, can be developed.
