Inborn Errors of Immunity Panel | NGS

Genes Sequenced9 genes sequenced: FAS, JAK1, KRAS, NRAS, PIK3CD, PIK3R1, STAT5B, TLR8 and UBA1.
Test DetailsThis targeted hybrid capture-based test is designed to detect somatic single nucleotide variants, insertions and deletions (indels). At a mean depth of coverage of at least 4000x across the captured region, this test has 89.84% sensitivity for variants at a variant allelic fraction (VAF) of 1.25% and 99.48% for variants at a VAF of at least 2.5%. Identified variants classified using ACMG/AMP, ClinGen and internally developed guidelines.
