Pancreatitis: Three-gene Profile (PRSS1, SPINK1, CFTR) (Full Gene Sequencing)
Use
This test is used for the full sequencing of the PRSS1, SPINK1, and CFTR genes to detect known variants associated with chronic pancreatitis. It involves sequencing all coding regions of these genes, including flanking intronic nucleotides and conserved splice sites, as well as UTR regions. This is typically conducted to support a diagnosis or assess risk in individuals suspected of having hereditary pancreatitis conditions or related syndromes.
Special Instructions
Not provided.
Limitations
The test is unable to reliably detect mosaic variants, large deletions, large duplications, deep intronic variants, and certain rearrangements. Factors such as allele dropout and the inability to detect the exact number of microsatellite repeats may impede certain analyses. Diagnosis based on this test should be clinically correlated due to its analytical limitations.
