01

Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Individuals with symptoms suggestive of D-bifunctional protein deficiency (e.g., developmental delays, liver dysfunction, metabolic imbalances).
  • ✓Patients with unexplained metabolic disorders.
  • ✓Individuals with a family history of D-bifunctional protein deficiency.
  • ✓Confirmation of diagnosis in suspected cases.
  • ✓Genetic counseling for families with affected members.
02

In plain language

What this test helps you understand

This test helps diagnose D-bifunctional protein deficiency by identifying mutations in the HSD17B4 gene. It aids in understanding the genetic cause of metabolic disorders, guiding treatment strategies, and providing information for genetic counseling and family planning.
The HSD17B4 Gene D-Bifunctional Protein Deficiency NGS Genetic DNA Test is a diagnostic tool used to identify mutations in the HSD17B4 gene. These mutations are linked to metabolic disorders, specifically D-bifunctional protein deficiency, which affects the body's ability to process fatty acids. This test utilizes Next Generation Sequencing (NGS) technology for accurate and comprehensive analysis. Understanding the genetic basis of these disorders is crucial for effective patient management and treatment planning. This test can help identify the specific genetic changes causing the condition, leading to more personalized care.

MethodologyNext Generation Sequencing (NGS) of the HSD17B4 gene.
PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test detects mutations within the HSD17B4 gene. It may not detect all possible mutations (e.g., deep intronic mutations, large deletions/duplications not detectable by NGS). A negative result does not completely rule out D-bifunctional protein deficiency if clinical suspicion remains high. Results must be interpreted in the context of clinical findings and family history.

What common result terms mean

PositiveA finding was identified. Your clinician or counselor will explain what it means for your care.
NegativeThe specific finding tested for was not identified. It does not rule out every possible cause.
VUSA variant was found, but current evidence is not enough to classify it. Your counselor can explain follow-up.
