An Oakland County toddler&#8217;s rare diagnosis is raising awareness"},"content":{"rendered":"<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">WATERFORD, Mich. \u2013 Only about 150 people in the world are living with an ultra-rare genetic disorder called CACNA1E, according to experts. A 1-year-old girl in Waterford is one of them.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">Her family says a lack of awareness makes finding treatment hard. They want to change that.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\"><a href=\"https:\/\/www.clickondetroit.com\/news\/local\/2026\/05\/19\/waterford-toddler-with-ultra-rare-genetic-disorder-could-lose-lifesaving-treatment-over-insurance-dispute\/\" target=\"_blank\" rel=\"noreferrer nofollow noopener\" title=\"https:\/\/www.clickondetroit.com\/news\/local\/2026\/05\/19\/waterford-toddler-with-ultra-rare-genetic-disorder-could-lose-lifesaving-treatment-over-insurance-dispute\/\">In May, Local 4 reported on 1-year-old Lorelei Dunn\u2019s story. <\/a>At the time, she could have lost her shot at lifesaving treatment because her insurance coverage could have been canceled.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">After the story aired, things turned around. But now, her family wants others to know why that research and treatment are so important on this CACNA1E Awareness Day.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">\u201cShe gets these three twice a day, this one once a day,\u201d Kayleigh Dunn, Lorelei\u2019s mom, said. \u201cThese two I have to crush up and mix with water \u2013 which is a lot harder than you would think it is.\u201d<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">That\u2019s how Mom Dunn begins each day, with a careful routine centered on caring for Lorelei.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">Just a few years ago, Dunn never imagined she would become an expert on one of the rarest genetic mutations in the world. That all changed when her family got the diagnosis.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">Lorelei was just a few months old.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">\u201cBecause of that, it causes her to have a seizure disorder,\u201d Dunn said. \u201cShe has severe hypotonia. She cannot hold her head up. She has no trunk support. Because of some complications we\u2019ve had with eating, she does have a feeding tube.\u201d<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">There are only about 150 people in the world who are known to have CACNA1E \u2013 and Lorelei is one of only 30 with her specific mutation.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">When the diagnosis came, the family was told their options were scarce and nearly nonexistent.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">Then, they connected with a renowned neurologist at the University of Michigan Medicine.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">The neurologist told them about a specific gene therapy that could help. Hopeful and grateful, the family wanted to get the process moving.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">But in May, that possibility was nearly pulled out from under them when their insurance coverage was threatened.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">\u201cIf we had lost our coverage and we were going to have to move, see a different neurologist,\u201d Dunn said. \u201cThere was no neurologist in the state of Michigan that we found that would be willing to take this on. This is a big \u2026 to do what we want to do, they have to agree to a case study. It means long hours, extra shifts.\u201d<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">Local 4 told their story, and eventually, the coverage was extended. With that came renewed hope and Lorelei\u2019s chance at treatment.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">Her family says awareness fuels research, and research can open the door to lifesaving care.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">\u201cShe\u2019s proven time and time again that she is not defined by her mutation, but it\u2019s my life, and it\u2019s tough. It\u2019s tough, right,\u201d Dunn said.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">To support Lorelei and her family, <a href=\"https:\/\/www.gofundme.com\/f\/faith-love-lorelei-the-dunn-familys-journey?attribution_id=sl:d238edec-2efb-4800-8127-bd5813088301&amp;lang=en_US&amp;ts=1765393761&amp;utm_campaign=fp_sharesheet&amp;utm_content=amp17_ta&amp;utm_medium=customer&amp;utm_source=copy_link\" target=\"_blank\" rel=\"nofollow noopener\">click this link.<\/a><\/p>\n<p>What is CACNA1E?<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\">According to <a href=\"https:\/\/www.cacna1e.org\/about-cacna1e\/\" target=\"_blank\" rel=\"noreferrer nofollow noopener\" title=\"https:\/\/www.cacna1e.org\/about-cacna1e\/\">CACNA1E International<\/a>, CACNA1E is an abbreviation of the gene\u2019s full name, \u201cCAlcium voltage-gated ChaNnel subunit Alpha 1E.\u201d <\/p>\n<p class=\"sc-dLMFU sc-fHjqPf dnEXRF\">\u201cCACNA1E is one out of 20,000-25,000 genes in our body and plays a role in the communication between neurons in the brain. It is located on the short arm of chromosome 1 at position 25.3 and encodes the neuronal<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf dnEXRF\">R-Type CaV2.3 channel. This subunit helps to form the channel pore (hole) through which ions flow. A change in the gene changes the function of the channel and affects the release of neurotransmitters.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf dnEXRF\">Normal calcium channels, without a mutation, open and closes regularly.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf dnEXRF\">All previous studies showed that CACNA1E shows up as a \u201cGain of function\u201d modification. <\/p>\n<p class=\"sc-dLMFU sc-fHjqPf dnEXRF\">This means that the calcium channel opens and stays open for a long time. As a result, calcium ion influx is increased, causing too much neuron excitability.<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf dnEXRF\">Mutations in CACNA1E causes a number of neurological phenotypes (=observable characteristics).<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf dnEXRF\">Most affected individuals present in infancy with epilepsy (refractory seizures, most commonly spasms) and developmental delay or no development at all. Many patients have joint contractures (hands or feet pull to the side &#8211; google: \u201culnar deviation\u201d, clubbed feet, &#8230;) and macrocephaly (a bigger head).&#8221;<\/p>\n<p>CACNA1E International<\/p>\n<p class=\"sc-dLMFU sc-fHjqPf jbiTJv kYFPaL article-text\"><a href=\"https:\/\/www.cacna1e.org\/about-cacna1e\/\" target=\"_blank\" rel=\"nofollow noopener\">You can find more information about CACNA1E here.<\/a><\/p>\n<p>Copyright 2026 by WDIV ClickOnDetroit &#8211; All rights reserved.<\/p>\n","protected":false},"excerpt":{"rendered":"WATERFORD, Mich. \u2013 Only about 150 people in the world are living with an ultra-rare genetic disorder called&hellip;\n","protected":false},"author":2,"featured_media":461548,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[34],"tags":[143,904,145,144,30022,8093],"class_list":["post-461547","post","type-post","status-publish","format-standard","has-post-thumbnail","category-oakland","tag-oakland","tag-oakland-county","tag-oakland-headlines","tag-oakland-news","tag-waterford","tag-waterford-township"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/461547","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/comments?post=461547"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/461547\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/461548"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=461547"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=461547"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=461547"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
