Biotinidase Newborn Screening Overview

Biotinidase newborn screening test is used by doctors to detect and diagnose biotinidase deficiency in newborns. Biotinidase deficiency is an inherited condition where newborn babies have difficulty in processing proteins, carbohydrates, and fats in their body correctly. This condition is caused by a change in the BTD gene. This gene gives your body instructions for making the enzyme biotinidase. This condition makes it difficult for the baby’s body to produce energy and expel waste.

There are two types of biotinidase deficiency depending on the proper activity of biotinidase in the child’s body: severe (called profound biotinidase deficiency) and mild (called partial biotinidase deficiency). Without appropriate treatment this condition can cause serious complications for children as carbohydrates, proteins, and fats that are not broken down completely due to this condition can be toxic for the child. Hence adding biotin to the baby’s diet can allow these enzymes to function. The goal of this test is to measure the activity of the enzyme biotinidase and start appropriate treatment measures for the newborn.
