Holocarboxylase synthetase (HCS) deficiency was defined as a distinct genetic disorder several years after its initial clinical description, similar. Because of the acute and fulminant initial presentation of holocarboxylase synthetase (HCS) deficiency, treatment is almost always initiated in. Holocarboxylase synthetase deficiency is an inherited metabolic disorder in which the body is unable to use the vitamin biotin effectively. This disorder is.

OMIM Entry – # – HOLOCARBOXYLASE SYNTHETASE DEFICIENCY
Holocarboxylase synthetase deficiency MCD is a condition in which the body is unable to break down proteins and carbohydrates. People with this condition have trouble using deficiencg, a vitamin that helps turn certain carbohydrates and proteins into energy for the body.
Holocarboxylase synthetase deficiency is considered an organic acid condition because it can lead to a harmful buildup of organic acids and toxins in the body. Early detection and holoxarboxylase often can prevent the severe outcomes of MCD.
It is important to remember that an out-of-range screening result does not necessarily mean that your child has the condition. An out-of-range result may occur because the initial blood sample was too small or the test was performed too early. However, a few babies do have the condition, so it is very important that you go to your follow-up appointment for a confirmatory test. Because the harmful effects of untreated MCD can occur soon after birth, follow-up testing must be completed as soon as possible to determine whether or holofarboxylase your baby has the condition.
In some cases, follow-up testing may holocarbxoylase testing a very small sample of skin. Signs of holocarboxylase synthetase deficiency MCD begin in infancy, usually in the first few days of life. Many of these signs may occur when your baby eats foods that their body cannot break down. They can be triggered by long periods of time without eating, illnesses, and infections.
Holocarboxylase synthetase deficiency – Wikipedia
Babies with holocarboxylase synthetase deficiency MCD need to synthtase biotin supplements to replace the natural biotin that is not working correctly. Biotin is a holocarbixylase of vitamin that your body needs to digest food.
These supplements can prevent your baby from experiencing many of the signs of MCD mentioned in the Early Signs section. In some cases, biotin supplements can reverse any signs that are already present. This is usually the only treatment your baby will need, but it is important to start treatment early to avoid any life-threatening signs and symptoms.
If your baby takes biotin supplements, they can live a healthy life and have typical development. With biotin treatment, your child will not need restricted diets or activities. If holocarboxylase synthetase deficiency is not treated, children can develop seizures or permanent brain damage.
When we eat food, enzymes help break it down for energy. Vitamins are also important to help our bodies break down food. In holocarboxylase synthetase deficiency MCDthe enzyme holocarboxylase synthetase is not working correctly.
These other enzymes need biotin in order to break down food. When holocarboxylase synthetase is not working correctly, food cannot be broken down completely. This causes harmful holcoarboxylase to build up in the body. MCD is an autosomal recessive genetic condition. This means that a child must inherit two copies of the non-working gene for MCD, one from each parent, in order to have the condition.
The parents of a child with an autosomal recessive condition each carry one copy of the non-working gene, but they typically do not show signs and symptoms of the condition. While having a child with MCD is rare, when both parents are carriers, they can have more than one child with the condition. Learn more about autosomal recessive inheritance. Support groups can help connect families who have a child or other family member affected with holocarboxylase synthase deficiency with a supportive community of people who have experience and expertise in living with the holocarboxylaee.
These organizations offer resources for families, affected individuals, healthcare providers, and advocates. Some children with holocarboxylase synthase deficiency MCD have developmental delays. Because MCD is a genetic conditionyou may holkcarboxylase to talk with a genetics specialist. A genetic counselor or geneticist can help you understand the causes of the condition, discuss genetic testing for MCD, and understand what this diagnosis means for other family members and future pregnancies.
At this time, we do not have any family stories for this particular condition. If your family is affected by holocarboxylase synthetase MCDwe would love to hear from youso that others may benefit from your story.
Each family has a unique experience and each condition is very different. However, you may find it useful to read the stories of families affected by other conditions, such as biotinidase deficiency, that may have similar evaluations and treatment.
You can read stories of families affected by biotinadase deficiency on this support group website. Healthcare professionals can learn more about confirmatory testing by reading the American College of Medical Genetics and Genomics’ Algorithm for Diagnosis and ACT Sheet holocxrboxylase, a guide for follow-up after newborn screening.
