Of the 23 pairs, 22 are called autosomes, numbered 1 through 22.<\/p>\n\n\n\n<p>The remaining pair is called the sex chromosomes, and the combination of the X and Y chromosomes determines a person&#8217;s gender (males have an X and Y combination, females have an X and X combination).<\/p>\n\n\n\n<p>A single chromosome can be further divided into smaller parts, with a centromere in the center, which divides into a short arm and a long arm. The short arm is called &#8220;p&#8221; and the long arm is called &#8220;q.&#8221; For example, in the case of chromosome 5, the short arm is called 5p and the long arm is called 5q.

In approximately 85% of cases, neither parent has a chromosomal abnormality, and it is thought to be due to a mutation. Approximately 80% of mutations occur in the father&#8217;s sperm, and abnormalities occur when chromosomes are broken for some reason during the sperm formation process. There are individual differences in how much of the chromosome is missing, and&nbsp;generally<a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/partialdeletions\/?lang=en\">&nbsp;the larger&nbsp;<\/a><a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/partialdeletions\/?lang=en\">the deletion<\/a>&nbsp;, the more severe the symptoms tend to be.<\/p>\n\n\n\n<p>The remaining 10% or so are caused by unbalanced reciprocal translocations. This type occurs when one of the parents has a chromosomal abnormality called a &#8220;translocation,&#8221; and the disease is passed down from parent to child.<\/p>\n\n\n\n<p>The remaining 5% or so are called mosaic types, in which&nbsp;<a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/partialdeletions\/?lang=en\">chromosome deletions<\/a>&nbsp;occur during the cell division process of the fertilized egg after fertilization. In the fertilized egg, normal cells and cells with chromosomal abnormalities are mixed together like a &#8220;mosaic.&#8221; Since not all cells have chromosomal abnormalities, symptoms are generally mild.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"600\" height=\"400\" src=\"\/nipt\/wp-content\/uploads\/2021\/12\/Baby9-min.png\" alt=\"\u30af\u30ea\u30fb\u30c7\u30e5\u30fb\u30c1\u30e3\u30c3\u30c8\u75c7\u5019\u7fa4\uff08\u732b\u9cf4\u304d\u75c7\u5019\u7fa4\u30015p\u30de\u30a4\u30ca\u30b9\u75c7\u5019\u7fa4\uff09 \" class=\"wp-image-20172\"\/><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"c4\"><span class=\"ez-toc-section\" id=\"How_to_test_for_Cri_du_Chat_syndrome_cri-du-chat_syndrome_5p_minus_syndrome\"><\/span><strong>How to test for Cri du Chat syndrome (cri-du-chat syndrome, 5p minus syndrome)<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The diagnosis of Cri du Chat syndrome is made after birth based on physical findings and confirmed by a blood chromosomal test called the FISH method. Recently,&nbsp;<a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/\">a new type of prenatal testing called non-invasive prenatal genetic testing (NIPT)<\/a>&nbsp;has also become available that can detect&nbsp;small chromosomal&nbsp;<a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/partialdeletions\/?lang=en\">deletions that cause Cri du Chat syndrome.<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/\">NIPT (New Prenatal Testing)<\/a>&nbsp;is a new screening test that involves taking blood from the mother and analyzing the DNA fragments of the baby in the mother&#8217;s blood to check for chromosomal diseases and abnormalities. Tokyo Hygienic Laboratory, which is affiliated with&nbsp;<a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/\">Hiro Clinic NIPT<\/a>&nbsp;, has the latest genetic testing device called VeriSeqNIPT Solution V2, which makes it possible to detect small chromosomal abnormalities that are difficult to detect with other devices. (Although it cannot detect all cases of Cri du Chat syndrome, it can detect&nbsp;deletions&nbsp;<a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/partialdeletions\/?lang=en\">of 7 million bases or more.)<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/www.hiro-clinic.or.jp\/nipt\/nipt\/\">At Hiro Clinic NIPT,<\/a>&nbsp;it is possible to undergo chromosome testing immediately after confirming pregnancy with an ultrasound examination.<\/p>\n\n\n\n    <a href=\"\/nipt\/nipt\/nipt\/\" class=\"blog-card\">\n      <div class=\"blog-card-content\">\n          <div class=\"blog-card-title\">\u77e5\u7684\u969c\u304c\u3044\u304c\u308f\u304b\u308bNIPT\u3068\u306f\uff08NIPT\u306e\u57fa\u672c\uff09 <\/div>\n          <div class=\"blog-card-excerpt\">\u30d2\u30ed\u30af\u30ea\u30cb\u30c3\u30af\u3067\u884c\u3063\u3066\u3044\u308bNIPT\u306e\u307e\u3068\u3081\u3067\u3059\u3002\u30d2\u30ed\u30af\u30ea\u30cb\u30c3\u30af\u306eNIPT\u3067\u306f\u77e5\u7684\u969c\u5bb3\u30fb\u767a\u9054\u969c\u5bb3\u3092\u4f34\u3046\u591a\u6570\u306e\u75be\u60a3\u3092\u51fa\u751f\u524d\u306b\u691c\u51fa\u3059\u308b\u3053\u3068\u304c\u53ef\u80fd\u3067...<\/div>\n      <\/div>\n    <\/a>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"c5\"><span class=\"ez-toc-section\" id=\"Probability_of_getting_Cri_du_Chat_syndrome_Cry-the-Cat_syndrome_5p_minus_syndrome\"><\/span><strong>Probability of getting Cri du Chat syndrome (Cry-the-Cat syndrome, 5p minus syndrome)<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Cri du Chat syndrome is thought to occur in one in every 15,000 to 50,000 births, making it a relatively rare condition.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"c6\"><span class=\"ez-toc-section\" id=\"Treatment_for_Cri_du_Chat_syndrome_Cry-du-Chat_syndrome_5p_minus_syndrome\"><\/span><strong>Treatment for Cri du Chat syndrome (Cry-du-Chat syndrome, 5p minus syndrome)&nbsp;<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There is currently no specific treatment for Cri du Chat syndrome.
