Invitae Elevated C4-OH Test
Use
The Invitae Elevated C4-OH Test analyzes the HADH and HIBCH genes, which are associated with elevations of C4-OH acylcarnitine on newborn screening (NBS) or plasma acylcarnitine analysis. Genetic testing of this gene may confirm a diagnosis and help guide treatment and management decisions. Early diagnosis and detection may improve the long-term outcome of these patients and may prevent sudden death. Patients are responsive to diazoxide therapy.
Special Instructions
Not provided.
Limitations
The test has >99% analytical sensitivity and specificity for single nucleotide variants, insertions, and deletions <15bp, and exon-level deletions and duplications. Sensitivity for larger insertions and deletions may be marginally reduced. Certain structural rearrangements and variants in complex sequences may not be detected. Sequencing changes in promoter, non-coding exons, and non-coding regions are not covered unless guaranteed.
