HelpTest Code HYPBG Hypobetalipoproteinemia Gene Panel, Varies
Ordering Guidance
This gene panel contains genes in common with HCHLG / Hypercholesterolemia Gene Panel, Varies. These tests should not be ordered concurrently as they assist in diagnosing conflicting disorders. For low levels of cholesterol (hypocholesterolemia), order this test. For high levels of cholesterol (hypercholesterolemia), order HCHLG.
Customization of this panel and single gene analysis for any gene present on this panel are available. For more information see CGPH / Custom Gene Panel, Hereditary, Next-Generation Sequencing, Varies.
Targeted testing for familial variants (also called site-specific or known mutations testing) is available for the genes on this panel. See FMTT / Familial Variant, Targeted Testing, Varies. To obtain more information about this testing option, call 800-533-1710.

Useful For
Providing a genetic evaluation for patients with a personal or family history suggestive of familial hypobetalipoproteinemia
Genetics Test Information
This test utilizes next-generation sequencing to detect single nucleotide and copy number variants in 5 genes associated with familial hypobetalipoproteinemia: ANGPTL3, APOB, MTTP, PCSK9, and SAR1B. See Targeted Genes and Methodology Details for Hypobetalipoproteinemia Gene Panel and Method Description for additional details.
Identification of a disease-causing variant may assist with diagnosis, prognosis, clinical management, familial screening, and genetic counseling for familial hypobetalipoproteinemia.
Prior Authorization is available for this assay.
