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.

Our Pancreatitis panel includes next generation sequencing (NGS) of CPA1, CASR, PRSS1, SPINK1, CTRC, and CFTR. Genomic deoxyribonucleic acid (gDNA) is isolated from the patient’s specimen using a standardized kit and quantified. Sequence enrichment of the targeted coding exons and adjacent intronic nucleotides is carried out by a bait-capture methodology using long biotinylated oligonucleotide probes, followed by polymerase chain reaction (PCR) and next generation sequencing (NGS). Additional Sanger sequencing is performed for any regions missing, or with insufficient read depth coverage for reliable heterozygous variant detection. Potentially homozygous variants, variants in regions complicated by pseudogene interference, and variant calls not satisfying depth of coverage and variant allele frequency quality thresholds are verified by Sanger sequencing. 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.
