- Peroxisome biogenesis disorders, also called Zellweger syndrome spectrum (PBD, ZSS) that include Zellweger syndrome (ZS), neonatal adrenoleukodystrophy (NALD), and infantile Refsum disease (IRD).
- X-linked adrenoleukodystrophy and adrenomyeloneuropathy.
- Rhizomelic Chondrodysplasia Punctata, Types 1, 2, and 3.
- Refsum Disease or phytanoyl-CoA hydroxylase deficiency.
- Acyl-CoA oxidase (ACOX1) deficiency.
- D-bifunctional protein (DBP) deficiency
- 2-Methylacyl-CoA racemase (AMACR) deficiency.
- Hyperoxaluria Type 1 or alanine glyoxylate aminotransferase deficiency.
- Mulibrey nanism.
- Sterol carrier protein X (SCP2) deficiency.
- DNM1L-related encephalopathy.
- ABCD3-related congenital bile acid synthesis defect
This test is indicated for:
- Confirmation of a clinical/biochemical diagnosis of peroxisomal disorders.
- Carrier testing in adults with a family history of peroxisomal disorders.
Please note that a "backbone" of probes across the entire genome are included on the array for analytical and quality control purposes. Rarely, off-target copy number variants causative of disease may be identified that may or may not be related to the patient's phenotype. Only known pathogenic off-target copy number variants will be reported. Off-target copy number variants of unknown clinical significance will not be reported.
