This disorder leads to a build-up of these sugars in various organs and tissues, causing progressive damage and multiple symptoms. Sanfilippo Syndrome is a serious condition that can cause significant developmental delays, cognitive impairment, childhood dementia, and physical abnormalities.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">In this article, experts at the <\/span><a href=\"\/pemc-florida\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400\">Pediatric Endocrine and Metabolic Center of Florida<\/span><\/a><span style=\"font-weight: 400\"> will explore the causes, symptoms, and treatment options for Sanfilippo Syndrome and current support options for affected individuals and families.<\/span><\/p>\n<h2><b>What Causes Sanfilippo Syndrome?<\/b><\/h2>\n<p><span style=\"font-weight: 400\">Sanfilippo Syndrome is caused by mutations in the genes responsible for producing specific enzymes needed to break down complex sugars called heparan sulfate. These enzymes are necessary for the normal metabolism of these sugars, and their build-up in the body causes the symptoms of Sanfilippo disease.<\/span><\/p>\n<p><span style=\"font-weight: 400\">There are four types of Sanfilippo Syndrome, each caused by a different gene mutation:\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Type A is caused by a mutation in the SGSH gene.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Type B is caused by a mutation in the NAGLU gene.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Type C is caused by a mutation in the HGSNAT gene.<\/span><\/li>\n<li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Type D is caused by a mutation in the GNS gene.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">The disorder is inherited in an autosomal recessive pattern, meaning a child has to inherit two copies of the mutated gene (one from each parent) to develop the condition. If a person inherits only one copy of the mutated gene, they will be a carrier of the disorder but will not develop symptoms.<\/span><\/p>\n<p><span style=\"font-weight: 400\">It is a rare disorder, with an estimated incidence of 1 in 70,000 live births. It occurs in all ethnic groups, and both males and females are affected equally. The disorder is usually diagnosed in early childhood and can lead to severe cognitive and physical developmental problems.<\/span><\/p>\n<h2><b>The Signs and Symptoms of Sanfilippo Syndrome<\/b><\/h2>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-1981\" src=\"https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/The-Signs-and-Symptoms-of-Sanfilippo-Syndrome.jpg\" alt=\"Doctor Give High Five To Cute Small 7S Boy Patient at Consultation With Mom in Hospital\" width=\"1000\" height=\"667\" srcset=\"https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/The-Signs-and-Symptoms-of-Sanfilippo-Syndrome-200x133.jpg 200w, https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/The-Signs-and-Symptoms-of-Sanfilippo-Syndrome-300x200.jpg 300w, https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/The-Signs-and-Symptoms-of-Sanfilippo-Syndrome-400x267.jpg 400w, https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/The-Signs-and-Symptoms-of-Sanfilippo-Syndrome-600x400.jpg 600w, https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/The-Signs-and-Symptoms-of-Sanfilippo-Syndrome-768x512.jpg 768w, https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/The-Signs-and-Symptoms-of-Sanfilippo-Syndrome-800x534.jpg 800w, https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/The-Signs-and-Symptoms-of-Sanfilippo-Syndrome.jpg 1000w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p>\n<p><span style=\"font-weight: 400\">The signs and symptoms of Sanfilippo disease can vary depending on the type of the disorder and the severity of the gene mutation. However, some common symptoms are seen in all types of the disorder.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Children with Sanfilippo Syndrome may struggle with memory, attention, and problem-solving skills. They may display aggression, self-injurious behavior, and sleep disturbances. In the early stages of the disorder, affected children may have delayed developmental milestones such as delayed speech and language development, difficulty with fine motor skills, and hyperactivity. As the disorder progresses, cognitive impairment, behavioral problems, and childhood dementia may become more pronounced.<\/span><\/p>\n<p><span style=\"font-weight: 400\">The physical symptoms of Sanfilippo disease include coarse facial features, enlarged liver and spleen, joint stiffness, and skeletal deformities. Children with the disorder may also experience recurrent infections, hearing loss, and vision problems.<\/span><\/p>\n<p><span style=\"font-weight: 400\">In type A and type B, symptoms usually appear between the ages of two and six, while type C and type D symptoms usually appear between the ages of four and eight. As the disorder progresses, affected individuals may experience a decline in their overall health and develop complications such as respiratory infections, sleep apnea, and heart problems.<\/span><\/p>\n<p><span style=\"font-weight: 400\">It is important to note that the symptoms and progression of the disorder can vary widely among affected individuals, even among those with the same type of disease. Early diagnosis and Sanfilippo Syndrome treatment are crucial to managing the symptoms and complications of the disorder.<\/span><\/p>\n<h2><b>How Is Sanfilippo Syndrome Diagnosed?<\/b><\/h2>\n<p><span style=\"font-weight: 400\">Sanfilippo Syndrome is a rare genetic disorder, and diagnosis can be challenging. A combination of tests is usually used to diagnose the disorder, including:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><b>Physical examination<\/b><span style=\"font-weight: 400\">: Your doctor will perform a physical examination to look for common physical characteristics of Sanfilippo Syndrome, such as coarse facial features, joint stiffness, and skeletal deformities.<\/span><\/li>\n<li style=\"font-weight: 400\"><b>Blood tests<\/b><span style=\"font-weight: 400\">: Blood tests will be performed to measure the levels of specific enzymes that break down complex sugars called heparan sulfate. Low levels of these enzymes can indicate Sanfilippo Syndrome.<\/span><\/li>\n<li style=\"font-weight: 400\"><b>Genetic testing<\/b><span style=\"font-weight: 400\">: Genetic testing can confirm the diagnosis of Sanfilippo Syndrome by identifying the specific gene mutation responsible for the disorder. This test is usually done after a positive result from a blood test.<\/span><\/li>\n<li style=\"font-weight: 400\"><b>Imaging studies<\/b><span style=\"font-weight: 400\">: Imaging studies such as X-rays, CT scans, or MRI may be performed to look for signs of organ damage or other disorder complications.<\/span><\/li>\n<li style=\"font-weight: 400\"><b>Developmental assessments<\/b><span style=\"font-weight: 400\">: Developmental assessments such as cognitive, speech, and language checks may be performed to evaluate the child&#8217;s developmental milestones and cognitive function.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">It is important to note that the symptoms of Sanfilippo Syndrome can be similar to those of other conditions, so a combination of tests is usually needed to confirm a diagnosis. A genetic counselor can help families understand the results and implications of genetic testing. An early diagnosis also allows families to plan for the future and access support services.<\/span><\/p>\n<h2><b>Sanfilippo Syndrome Treatment Options<\/b><\/h2>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-1982\" src=\"https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/Sanfilippo-Syndrome-Treatment-Options.jpg\" alt=\"Doctor and Little Girl Patient Using Digital Tablet Sharing Good Health Test News With Happy Mom Sit On Couch in House\" width=\"1000\" height=\"527\" srcset=\"https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/Sanfilippo-Syndrome-Treatment-Options-200x105.jpg 200w, https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/Sanfilippo-Syndrome-Treatment-Options-300x158.jpg 300w, https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/Sanfilippo-Syndrome-Treatment-Options-400x211.jpg 400w, https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/Sanfilippo-Syndrome-Treatment-Options-600x316.jpg 600w, https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/Sanfilippo-Syndrome-Treatment-Options-768x405.jpg 768w, https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/Sanfilippo-Syndrome-Treatment-Options-800x422.jpg 800w, https:\/\/www.toplinemd.com\/pemc-florida\/wp-content\/uploads\/sites\/111\/2023\/02\/Sanfilippo-Syndrome-Treatment-Options.jpg 1000w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p>\n<p><span style=\"font-weight: 400\">There is currently no cure for this disorder, and Sanfilippo Syndrome treatment options are primarily focused on managing its symptoms and complications.
