Biotinidase Deficiency (BTD) Gene Analysis

The Biotinidase Deficiency (BTD) Gene Analysis is a genetic test that examines the BTD gene for disease-causing variants associated with biotinidase deficiency, an inherited metabolic disorder. Changes in this gene can reduce or eliminate the activity of the biotinidase enzyme, preventing the body from effectively recycling biotin (vitamin B7). This test helps identify the genetic cause of the condition, confirms a suspected diagnosis, and supports carrier detection, family screening, and genetic counselling for individuals at risk.

Who should get this test done?

This test may be recommended for individuals who:

●     Have symptoms suggestive of biotinidase deficiency, such as developmental delay, seizures, hearing problems, or muscle weakness.

●     Have an abnormal newborn screening result indicating possible biotinidase deficiency.

●     Have a family history of biotinidase deficiency or a known BTD gene mutation.

●     Require genetic confirmation of a suspected inherited metabolic disorder.

●     Are planning a family and wish to determine their carrier status for biotinidase deficiency.

Why consider this test?

The Biotinidase Deficiency (BTD) Gene Analysis provides a detailed evaluation of the BTD gene to identify genetic changes responsible for this inherited metabolic disorder. Confirming the underlying genetic cause can help healthcare professionals better understand the condition and support personalised clinical care. The test is also valuable for identifying carriers within affected families, guiding reproductive planning, and providing important information through genetic counselling. It plays a key role in the long-term management of individuals with inherited metabolic conditions.

More Information

The BTD gene contains the instructions for producing the biotinidase enzyme, which is responsible for recycling biotin so it can be reused by the body. Genetic changes in this gene can reduce enzyme activity and affect several metabolic pathways that depend on biotin. This analysis examines the BTD gene for disease-associated variants, providing a comprehensive assessment of the genetic basis of biotinidase deficiency. The information gained from this test helps clarify the inherited nature of the condition and supports family-based risk assessment.
