Under this premise, at IVI we advocate offering genetic screening tests in assisted reproduction centres in a systemic way. In fact, in some countries preconception carrier screening is indicated to any couple wishing to become pregnant, through family medicine, as is the case in Israel, for example\u201d, said Dr. Pla.<\/p>\n<p>Prevention involves preconception genetic testing to inform about the <strong>risk or the predisposition to suffer from certain illnesses or troubles<\/strong>.<\/p>\n<p>\u201c<a href=\"https:\/\/ivi-fertility.com\/assisted-reproduction-treatments\/pgd-pgt\/\">Preconception genetic testing<\/a> as a preventive tool aims to inform people about the risk of having children with autosomal recessive and X-linked recessive disorders. This enables informed decision-making about their reproductive choices. Preconception genetic testing as a widespread practice among women or couples considering starting a family would drastically reduce the prevalence of this type of hereditary disease\u201d, added Dr. Pla.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Most_frequent_inherited_diseases\"><\/span>Most frequent inherited diseases<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In the last two decades, <strong>more than 1,300 recessive inherited disorders<\/strong> with mild to severe impact on health and life expectancy have been identified. Among the most frequent diseases in the population &#8211; high frequency of carriers &#8211; we could highlight the following:<\/p>\n<ul>\n<li>Cystic fibrosis (1 in 25-30 people are carriers)<\/li>\n<li>Alpha and beta thalassaemia (1 in 25-30 people are carriers)<\/li>\n<li>Non-syndromic hearing loss (1 in 30-40 people are carriers)<\/li>\n<li>Spinal muscular atrophy (1 in 45 people are carriers)<\/li>\n<li>Congenital adrenal hyperplasia (1 in 50 people are carriers)<\/li>\n<li>Everyone is a carrier of between 3 and 5 recessive genetic mutations, which does not mean they suffer from the disease. But if they get pregnant with another person with the same altered gene, there is a 25% risk that the children will suffer from this disease.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"i\"><\/span>\u00a0<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h2><span class=\"ez-toc-section\" id=\"Genetic_compatibility_tests\"><\/span>Genetic compatibility tests<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>At IVI we made the so-called <a href=\"https:\/\/ivi-fertility.com\/assisted-reproduction-treatments\/cgt-547\/\">genetic compatibility test<\/a> available to our patients many years ago. Thanks to these we can discover which mutations each individual has and whether there is a risk of transmission to offspring.<\/p>\n<p>\u201cWhatever the result, the <strong>genetic counselling service<\/strong> will explain to our patients the reproductive options available to them in order to achieve their objective with the highest guarantees. Furthermore, this test is compulsory for all our donors. The reason is\u00a0to offer patients who make use of these donated gametes the greatest security in their processes\u201d, explained Dr. Pla.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"New_horizons_in_reproductive_genetics\"><\/span>New horizons in reproductive genetics<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Genetics is here to stay. This is demonstrated by the &#8216;<strong>genetic revolution<\/strong>&#8216; we have experienced in recent years. According to Dr. Pla, the future of genetics in reproductive medicine can be outlined along these 3 lines.<\/p>\n<p>First, the individual study of each case will continue to focus on genetic testing to find out the exact problem that stands between the patient and paternity\/maternity. This will increase the personalization of each treatment.<\/p>\n<p>Then, the increasing number of studies available before pregnancy will allow for a robust model of preventive medicine. In this way, some diseases that until now had no known cause will begin to have an identified cause that helps to make reproductive choices.<\/p>\n<p>And finally, <strong>gene editing<\/strong>, which makes it possible to correct or alter an individual&#8217;s genetic information. This is a field that has shown promise for years, but has been held back, in part, by the legal and ethical considerations that have arisen around it.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Genetic_counsellors\"><\/span>Genetic counsellors<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>Genetic counsellors<\/strong> will become a key figure in reproductive medicine, enabling the patient to make autonomous decisions.<\/p>\n<p>\u201cThis revolution will not stop. The growth seen in genetic testing, coupled with the significant reduction in the price of these tests will make this possible. We cannot imagine a future of assisted reproduction without a strong influence from genetics. There is an increasing tendency to include genetic counsellors, as has been the case at IVI for years, to accompany and bring this type of information closer to the patient\u201d, concluded Dr. Pla.<\/p>\n","protected":false},"excerpt":{"rendered":"According to the World Health Organisation (WHO), at least 1 in 100 couples in the general population is at high risk of having a child with a
