This Rare Disease Makes Babies Appear Healthy, But Their Brains Deteriorate Slowly

This Rare Disease Makes Babies Appear Healthy, But Their Brains Deteriorate Slowly. Imagine a baby who looks normal and healthy, but in silence, their body fails to process an essential vitamin. As a result, brain cells begin to deteriorate one by one without being noticed. This is the reality for those suffering from biotinidase deficiency, a rare genetic disease. Without early treatment, it can cause seizures, hearing loss, and lifelong learning problems.. When Vitamin 'H' Becomes a Matter of Life and Death Have you ever heard of biotin? If not, don't worry — many people don't know. Biotin, or vitamin B7, is a water-soluble nutrient crucial for metabolizing fats, carbohydrates, and proteins. But what happens if our bodies can't use the biotin we have? That's exactly what happens to people with biotinidase deficiency, a very rare autosomal recessive metabolic disorder. Biotinidase is an enzyme that releases biotin from proteins in food. When this enzyme doesn't function properly, biotin cannot be recycled within the cell. As a result, the body's biotin stores quickly run out, and cells start starving. Without biotin, our bodies cannot produce energy properly — especially in the brain and nervous system. Symptoms: From Dry Skin to Coma In the early stages, symptoms of biotinidase deficiency may appear like common issues: dry skin, hair loss, or red rashes around the eyes and mouth. But don't be deceived — within a few weeks or months, the condition can become more severe. Babies affected may experience seizures, weak muscles, coordination problems, and slow brain development. In severe cases, they can fall into a coma. Neurological symptoms such as hearing loss, vision problems, and developmental delays can also occur. The most alarming part: all of this can be prevented if detected early. Who Is at Risk? The Answer Lies in DNA Biotinidase deficiency is a genetic disease. That means it is inherited from parents who each carry one copy of the defective gene. When two carriers marry, each child has a 25% chance of inheriting two copies of the faulty gene and developing the disease. This disease is rare, but more common in certain populations. In Europe, the prevalence rate is about 1 in 60,000 to 1 in 200,000 births. In Malaysia? Data is limited, but experts suspect many cases go undiagnosed because the symptoms can be mistaken for other diseases. Diagnosis: A Simple Test That Saves Lives Fortunately, there is an easy way to detect biotinidase deficiency — a newborn screening test. Only a drop of blood from the baby's heel is needed. This test is already routine in many developed countries, but in Malaysia, it is not yet nationally mandated. If a baby is diagnosed early, the treatment is very simple: daily biotin supplements. Just by taking an adequate dose of biotin, symptoms can be completely controlled. Moreover, most children who receive early treatment can live normally without any problems. But if the diagnosis is delayed, the nerve damage that has already occurred may be permanent. That's why awareness of this disease is so important. Parents need to know that rashes, seizures, or developmental delays are not something to be taken lightly. Hope Behind a Vitamin Although it sounds frightening, the good news is: biotinidase deficiency can be easily managed. With just one biotin pill a day, these children can lead lives like their peers. They can go to school, play, and dream big — without worrying about seizures or brain damage. The key is not the treatment, but early detection. Every baby born deserves a chance to live healthily. And sometimes, that chance comes in the form of a drop of blood and a small vitamin. --- Reference: Biotinidase deficiency — Wikipedia https://en.wikipedia.org/wiki/Biotinidase deficiency
