href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a> is a disorder caused by abnormalities in the chromosomes, which contain the genes and DNA inherited from the parents.<\/p>\n\n\n\n<p>Normally, 23 chromosomes are inherited from the father and 23 from the mother, for a total of 46 chromosomes. However, in <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a>, there is an extra copy of the 21st chromosome, leading to various intellectual and physical disabilities.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a> is a disorder that was described in 1866 and is named after Dr. Down, who reported it in a paper. Among chromosomal abnormalities, which occur due to abnormalities in the chromosomes, <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a> is considered one of the most common disorders. Its incidence rate is about 1 in 600 to 800 people.<\/p>\n\n\n\n<p>However, as the mother&#8217;s age at childbirth increases, the likelihood of the baby having <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a> also rises. Additionally, if the mother has <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a>, the probability of the baby having <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a> is higher compared to a mother who does not have Down syndrome.<\/p>\n\n\n\n    <a href=\"\/nipt\/about-down-syndrome\/\" class=\"blog-card\">\n      <div class=\"blog-card-content\">\n          <div class=\"blog-card-title\">\u30c0\u30a6\u30f3\u75c7\uff0821\u30c8\u30ea\u30bd\u30df\u30fc\uff09\u3068\u306f\uff1f\u539f\u56e0\u3084\u7279\u5fb4\u30fb\u691c\u67fb\u65b9\u6cd5\u3092\u89e3\u8aac <\/div>\n          <div class=\"blog-card-excerpt\">\u30c0\u30a6\u30f3\u75c7\uff0821\u30c8\u30ea\u30bd\u30df\u30fc\uff09\u3068\u306f\uff1f\u539f\u56e0\u3084\u7279\u5fb4\u3001\u907a\u4f1d\u306e\u53ef\u80fd\u6027\u3001\u9ad8\u9f62\u51fa\u7523\u3068\u306e\u95a2\u4fc2\u3001\u75c7\u72b6\u3001\u652f\u63f4\u5236\u5ea6\u306a\u3069\u3092\u8a73\u3057\u304f\u89e3\u8aac\u3002\u598a\u5a20\u4e2d\u306e\u4e0d\u5b89\u306b\u5bc4\u308a\u6dfb\u3046\u60c5\u5831\u3092\u63d0\u4f9b...<\/div>\n      <\/div>\n    <\/a>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"c2\"><span class=\"ez-toc-section\" id=\"Facial_Features_of_Down_Syndrome\"><\/span>Facial Features of Down Syndrome<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>When <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a> occurs, characteristic facial features appear.<\/p>\n\n\n\n<p>The main facial features of <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a> are as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Small head<\/li>\n\n\n\n<li>Broad, flat nose<\/li>\n\n\n\n<li>Slanted, narrow eyes<\/li>\n\n\n\n<li>Large tongue<\/li>\n\n\n\n<li>Excess skin at the back of the neck ,etc.<\/li>\n<\/ul>\n\n\n\n<p>While not all facial features necessarily appear in every case of <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a>, there is a tendency for these characteristic facial features to develop.<\/p>\n\n\n\n<p>In addition to facial features, physical characteristics include reduced muscle tone throughout the body, short fingers, and short stature. There is also a higher risk of obesity due to limited physical activity and dietary imbalances.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"c3\"><span class=\"ez-toc-section\" id=\"Complications_of_Down_Syndrome\"><\/span>Complications of Down Syndrome<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Individuals with <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a> may develop various complications. Approximately 50% have congenital heart disease, with ventricular septal defect and common atrioventricular canal being the most frequently occurring heart conditions.<\/p>\n\n\n\n<p>Additionally, there is a high frequency of gastrointestinal complications, such as duodenal obstruction or stenosis, Hirschsprung&#8217;s disease (a neurogenic disorder of the intestines), and celiac disease (which causes malabsorption). Other potential systemic complications include hypothyroidism, diabetes, and thrombocytopenia.<\/p>\n\n\n\n<p>In the past, individuals with <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a> were considered to have a short lifespan due to complications. However, with the advancement of medical treatments for complications associated with <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a>, the average life expectancy has increased to around 60 years, with some individuals living into their 70s and 80s.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"600\" height=\"400\" src=\"\/nipt\/wp-content\/uploads\/2022\/01\/confronting-down-syndrome02.jpg\" alt=\"\u30c0\u30a6\u30f3\u75c7\u306e\u5b50\u3069\u3082\" class=\"wp-image-22124\"\/><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"c4\"><span class=\"ez-toc-section\" id=\"Intellectual_Disability_in_Down_Syndrome\"><\/span>Intellectual Disability in Down Syndrome<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Many individuals with <a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/about-down-syndrome\/?lang=en\">Down syndrome<\/a> experience intellectual disabilities along with various physical symptoms.<\/p>\n\n\n\n<p>The degree of intellectual disability ranges widely, from mild intellectual disabilities with an IQ of around 50\u201375 to severe intellectual disabilities with an IQ of around 20\u201335. Additionally, there may be issues such as lack of attention, hyperactivity, and autistic behaviors, with the latter being more common in individuals with more pronounced intellectual disabilities.
