Is biotinidase deficiency an autosomal recessive disorder?

Biotinidase deficiency has an autosomal recessive pattern of inheritance. Mutations in the BTD gene cause biotinidase deficiency. Biotinidase is the enzyme that is made by the BTD gene. Many mutations that cause the enzyme to be nonfunctional or to be produced at extremely low levels have been identified.

What are the symptoms of biotinidase deficiency in newborns?

Babies may be born without signs of biotinidase deficiency, but the symptoms become apparent after the first few weeks or months of life. Chief characteristics include weak muscles (hypotonia), seizures, hair loss (alopecia), an inflammatory skin rash (eczema), developmental delays, and lactic aciduria.

How is biotin deficiency treated?

Biotin deficiency is reversible. People with BTD will be prescribed biotin supplements, which will stop the symptoms, but they will usually need to take the supplements long-term. The FDA does not monitor supplements as closely as they monitor food and drugs so a person should choose from a reputable source.

Can biotin deficiency cause seizures?

Patients with severe biotinidase deficiency (BD), if untreated, may exhibit seizures, psychomotor delay, deafness, ataxia, visual pathology, conjunctivitis, alopecia, and dermatitis. Clinical features normally appear within the first months of life, between two and five.

One in 110,000 people have partial biotinidase deficiency. One in 60,000 people have either profound or partial biotinidase deficiency. Approximately 1 in 120 people are carriers of one gene for BTD, but this number may be higher in the Hispanic population and lower in the African American population.

How common is biotin deficiency?

Biotin deficiency in humans is rare. The first indicator of human biotin deficiency appears to be a drop in urinary biotin, with a maintenance of plasma levels of the vitamin. The deficiency can result from a rare genetic deficiency in biotinidase.

What is biotinidase deficiency?

Biotinidase deficiency is an inherited disorder in which the body is unable to recycle the vitamin biotin. The disorder may become apparent in the first few months of life, or later in childhood. The more severe form of the disorder is called 'profound biotinidase deficiency' and may cause delayed development, seizures, weak muscle tone ( hypotonia ), breathing problems, hearing and vision loss, problems with movement and balance ( ataxia ), skin rashes, hair loss (alopecia), and a fungal infection called candidiasis. The milder form is called 'partial biotinidase deficiency'; without treatment, affected children may experience hypotonia, skin rashes, and hair loss. In some cases, these symptoms only appear during illness, infection, or other times of stress on the body. Biotinidase deficiency is caused by mutations in the BTD gene and is inherited in an autosomal recessive manner. Lifelong treatment with biotin can prevent symptoms and complications from occurring or improve them if they have already developed. [1]

How long does it take for biotinidase deficiency to appear?

The signs and symptoms of biotinidase deficiency typically appear within the first few months of life , but the age of onset varies. Children with profound biotinidase deficiency, the more severe form of the condition, may have seizures, weak muscle tone ( hypotonia ), breathing problems, and delayed development.

Is biotinidase inherited?

What are the two types of biotinidase deficiency?

Biotinidase deficiency is sometimes categorized into groups depending on how much of the biotinidase enzyme is working. These two categories are profound BTD and partial BTD. People with profound BTD tend to have more severe symptoms earlier in life than people with partial BTD.

How to diagnose biotinidase deficiency in newborns?

Biotinidase deficiency can be diagnosed in newborns through newborn screening. Newborn screening is a special type of screening test that newborns receive to see if they have certain diseases. Because the newborn screen is a screening test, a positive result does not mean that an infant definitely has the disease.

What is the BTD gene?

The BTD gene instructs the body in creating the enzyme biotinidase that helps the body recycle an important vitamin called biotin (vitamin H). When the body is not able to recycle biotin, health concerns like the symptoms above can happen. We all have two copies of every gene.

What is BTD in biology?

Biotinidase deficiency ( BTD) deficiency is a treatable, inherited condition. BTD affects the way the body processes a vitamin called biotin (sometimes called vitamin H). Biotin is an important vitamin that helps the body break down protein, fats, and carbohydrates. Biotinidase is an enzyme that helps recycle biotin to be reused by the body.

What are the symptoms of BTD?

Some other common features of BTD include eye infections, like pink eye (conjunctivitis), hair loss (alopecia), and a certain type of skin rash called eczema. Infants with BTD may have specific molecules in their urine, such as lactic acid (lactic aciduria) or low but noticeable amounts of ammonia.

What is the risk of having a child with two carriers?

The risk for two carrier parents to both pass the non-working gene and, therefore, have an affected child is 25 percent with each pregnancy. The risk to have a child who is a carrier like the parents is 50 percent with each pregnancy.

Can biotinidase be taken for life?

With biotin treatment, symptoms of the disorder may disappear. However, a person with biotinidase deficiency may have to take biotin for his/her entire lifetime. Genetic counseling is recommended for families of a child with biotinidase deficiency.

What is biotin dependent carboxylase?

Biotin-dependent carboxylase deficiency. Clinical Information. A genetic disorder caused by mutations in the btd gene. It is characterized by reduced or absent activity of the enzyme biotinidase which is responsible for the recycling of the vitamin biotin.

What happens if you leave a carboxylase deficiency untreated?

If left untreated, it leads to vision and hearing loss, infections, alopecia and ataxia.
