We offer family variant testing for all blood relatives of patients who undergo full single gene sequencing, multigene panel testing or exome sequencing at Ambry Genetics and are found to have a pathogenic or likely pathogenic variant. Testing must be completed within 90 days of the original report date. Whenever possible, more closely related relatives should be tested before more distant relatives. If you or a family member are interested in learning more about our family testing program or when family testing may be clinically indicated, please contact us or your provider for additional information. Note that Ambry can only provide such family testing services to patients receiving medical care in the U.S or US territories.
Order NowClinical sensitivity for these genes is not well defined. Ambry's surfactant dysfunction testing can detect >99.9% of described mutations in the included genes, when present (analytic sensitivity).
Our Surfactant Dysfunction panel includes Sanger Sequencing of ABCA3, SFTPB, and SFTPC. Genomic deoxyribonucleic acid (gDNA) is isolated from the patient’s specimen using standardized methodology and quantified. All the analyzed regions of the gene are amplified through polymerase chain reaction (PCR) and sequence alterations are identified by double-stranded sequencing from sense and anti-sense directions. This test targets detection of DNA sequence mutations in all coding domains, and well into the 5’ and 3’ ends of all the introns and untranslated regions.
