    Introduction

    The pancreas is an important organ behind and below the stomach. It releases enzymes to help

    us digest our food and also releases hormones (insulin and glucagon) to help the body control

    how it uses the food for energy. If the pancreas becomes inflamed, it is called pancreatitis. In

    some people, pancreatitis may have come on suddenly and only lasts for a short time (acute

    pancreatitis). Other people may have been sick with pancreatitis for a long time (chronic

    pancreatitis). Chronic pancreatitis may seem to run in some families, and as a result these cases

    may be caused by genetic problems. Genetic testing has sometimes been done to see if a

    person has hereditary pancreatitis. This policy discusses when genetic testing for hereditary

    pancreatitis may be medically necessary.

    Note: The Introduction section is for your general knowledge and is not to be taken as policy coverage criteria. The

    rest of the policy uses specific words and concepts familiar to medical professionals. It is intended for

    providers. A provider can be a person, such as a doctor, nurse, psychologist, or dentist. A provider also can

    be a place where medical care is given, like a hospital, clinic, or lab. This policy informs them about when a

    service may be covered.

    Genetic Counseling

    Genetic counseling is primarily aimed at patients who are at risk for inherited disorders, and

    experts recommend formal genetic counseling in most cases when genetic testing for an

    inherited condition is considered. The interpretation of the results of genetic tests and the

    understanding of risk factors can be very difficult and complex. Therefore, genetic counseling

    will assist individuals in understanding the possible benefits and harms of genetic testing,

    including the possible impact of the information on the individuals family. Genetic counseling

    may alter the utilization of genetic testing substantially and may reduce inappropriate testing.

    Genetic counseling should be performed by an individual with experience and expertise in

    genetic medicine and genetic testing methods.

    Consideration of Age

    The age described in this policy for medical necessity of genetic testing for hereditary

    pancreatitis is age 18 and younger. Having recurrent pancreatitis in children is not very

    common. The literature regarding genetic testing for hereditary pancreatitis in children is sparse.

    Although there is a lot of evidence, there is consensus opinion from physician medical societies

    that, in children with more than one episode of pancreatitis, a positive result of this genetic

    testing may make additional invasive testing unnecessary. See the Evidence Review section

    below for more detail.

    Evidence Review

    Description

    In chronic pancreatitis (CP), recurrent attacks of acute pancreatitis evolve into a chronic

    inflammatory state with exocrine insufficiency, diabetes mellitus, and increased risk for

    pancreatic cancer. Hereditary pancreatitis (HP) is a subset of CP defined clinically as a familial

    pattern of CP. Variants of several genes are associated with HP. Demonstration of a pathogenic

    genetic variant in one or several of these genes can potentially be used to confirm the diagnosis

  • Page | 4 of 12

    of HP, provide information on prognosis and management, and/or determine the risk of CP in

    asymptomatic relatives of patients with HP.

    Background

    Pancreatitis

    Acute and chronic pancreatitis (CP) is caused by the premature activation of trypsinogen into

    trypsin within the pancreas, resulting in autodigestion, inflammation, increased levels of

    pancreatic enzymes in the serum, and abdominal pain. CP is defined as an ongoing

    inflammatory state associated with chronic/recurrent symptoms and progression to exocrine

    and endocrine pancreatic insufficiency.

    Alcohol is the major etiologic factor in 80% of CP, which has a peak incidence in the fourth and

    fifth decades of life. Gall stones, hypercalcemia, inflammatory bowel disease, autoimmune

    pancreatitis, and peptic ulcer disease can also cause CP. About 20% of CP is idiopathic.

    A small percentage of CP is categorized as hereditary pancreatitis (HP), which usually begins

    with recurrent episodes of acute pancreatitis in childhood and evolves into CP by age 20 years.

    Multiple family members may be affected over several generations, and pedigree analysis often

    reveals an autosomal dominant pattern of inheritance. Clinical presentation and family history

    alone are sometimes insufficient to distinguish between idiopathic CP and HP, especially early in

    the course of the disease. Individuals with HP have an estimated 40% to 55% lifetime risk of

    developing pancreatic cancer.1

    Genetic Determinants of Hereditary Pancreatitis (HP)

    PRSS1 Variant

    Whitcomb (2001) discovered that disease-associated variants of protease, serine, 1 (trypsin 1)

    (PRSS1) on chromosome 7q35 cause HP. PRSS1 encodes cationic trypsinogen. The gain of

    function variants of the PRSS1 gene cause HP by prematurely and excessively converting

    trypsinogen to trypsin, which results in pancreatic autodigestion. Between 60% and 80% of

    people who have a disease-associated PRSS1 variant will experience pancreatitis in their

    lifetimes; 30% to 40% will develop CP. Most, but not all, people with a disease-associated variant

    of PRSS1 will have inherited it from one of their parents. The proportion of HP caused by a de

    novo variant of PRSS1 is unknown. In families with 2 or more affected individuals in 2 or more

  • Page | 5 of 12

    generations, genetic testing has shown that most have a demonstrable disease-associated

    PRSS1 variant. In 60% to 100%, the variant is detected by sequencing technology (Sanger or

    next-generation), and duplications of exons or the whole PRSS1 gene are seen in about 6%. Two

    PRSS1 point variants (p.Arg122His, p.Asn29Ile) are most common, accounting for 90% of

    disease-associated variants in affected individuals. Over 40 other PRSS1 sequence variants have

    been found, but their clinical significance is uncertain. Pathogenic PRSS1 variants are present in

    10% or less of individuals with CP.2

    Targeted analysis of exons 2 and 3, where the common disease-associated variants are found, or

    PRSS1 sequencing, are first-line tests, followed by duplication analysis. The general indications

    for PRSS1 testing and emphasis on pre- and post-test genetic counseling have remained central

    features of reviews and guidelines.3,4 However, several other genes have emerged as significant

    contributors to both HP and CP. They include the cystic fibrosis (CF) transmembrane

    conductance regulator (CFTR) gene, serine peptidase inhibitor, Kazal type 1 (SPINK1) gene,

    chymotrypsin C (CTRC) gene, and claudin-2 (CLDN-2) gene.

    CFTR Variants

    Autosomal recessive variants of CFTR cause CF, a chronic disease with onset in childhood that

    causes severe sinopulmonary disease and numerous gastrointestinal abnormalities. The signs

    and symptoms of CF can vary widely. On rare occasions, an affected individual may have mild

    pulmonary disease, pancreatic exocrine sufficiency, and may present with acute, recurrent acute,

    or CP.3 Individuals with heterozygous variants of the CFTR gene (CF carriers) have a 3- to 4-fold

    increased risk for CP. Individuals with 2 CFTR variants (homozygotes or compound

    heterozygotes) will benefit from CF-specific evaluations, therapies, and genetic counseling.

    SPINK Variants

    The SPINK gene encodes a protein that binds to trypsin and thereby inhibits its activity. Variants

    in SPINK are not associated with acute pancreatitis but are found, primarily as modifiers, in

    recurrent acute pancreatitis and seem to promote the development of CP, including for

    individuals with compound heterozygous variants of the CFTR gene. Autosomal recessive

    familial pancreatitis may be caused by homozygous or compound heterozygous SPINK variants.5

  • Page | 6 of 12

    CTRC Variants

    CTRC is important for the degradation of trypsin and trypsinogen, and 2 variants (p.R254W and

    p.K247_R254del) are associated with an increased risk for idiopathic CP (odds ratio [OR], 4.6),

    alcoholic pancreatitis (OR =4.2), and tropical pancreatitis (OR =13.6).6

    CLDN2 Variants

    CLDN2 encodes a member of the claudin protein family, which acts as an integral membrane

    protein at tight junctions and has tissue-specific expression. Several single nucleotide

    polymorphisms in CLDN2 have been associated with CP.

    Genetic Testing for Variants

    Testing for variants associated with HP is typically done by direct sequence analysis or next-

    generation sequencing (NGS). A number of laboratories offer testing for the relevant genes,

    either individually or as panels. For example, ARUP Laboratories (Salt Lake City, UT) offers a

    Pancreatitis Panel, which includes direct (Sanger) sequencing of CFTR, CTRC, PRSS1, and SPINK.7

    Prevention Genetics (Marshfield, WI) offers a Chronic Pancreatitis Sequencing Panel, which

    includes NGS of 5 genes: CASR, CFTR, CTRC, PRSS1, and SPINK1.8 Ambry Genetics (Aliso Viejo,

    CA) offers a Pancreatitis Panel, which includes NGS of PRSS1, SPINK1, CTRC, and CFTR.9 Ambrys

    PancNext panel for variants associated with increased risk of pancreatic cancer consists of NGS

    of 13 genes: APC, ATM, BRCA1, BRCA2, CDKN2A, EPCAM, MLH1, MSH2, MSH6, PALB2, PMS2,

    STK11, and TP53.10

    Summary of Evidence

    For individuals who have CP or ARP who receive testing for genes associated with HP, the

    evidence includes cohort studies on variant detection rates and a systematic review. Relevant

    outcomes are test accuracy, symptoms, change in disease status, morbid events, and

    hospitalizations. There are studies on the detection rate of HP-associated genes in various

    populations. Few studies have enrolled patients with known HP; those doing so have reported

    detection rates for disease-associated variants between 52% and 62%. For other studies that

    tested patients with CP or ARP, disease-associated variant detection rates varied widely across

    studies. There is a lack of direct evidence that testing for HP improves health outcomes and

  • Page | 7 of 12

    insufficient indirect evidence that, in patients with CP or ARP, management would change after

    genetic testing in a manner likely to improve health outcomes. The evidence is insufficient to

    determine the effects of the technology on health outcomes.

    For individuals who are asymptomatic with family members with HP who receive testing for a

    known familial variant associated with HP, the evidence includes a very limited number of

    studies. Relevant outcomes are test accuracy, symptoms, change in disease status, morbid

    events, and hospitalizations. No direct evidence was identified comparing outcomes in patients

    tested or not tested for a familial variant. It is possible that at-risk relatives who are identified

    with a familial variant may alter lifestyle factors (eg, diet, smoking, alcohol use), and this might

    delay or prevent CP onset. However, studies evaluating behavioral changes and impact on

    disease are lacking. The evidence is insufficient to determine the effects of the technology on

    health outcomes.

    Ongoing and Unpublished Clinical Trials

    A search of ClinicalTrials.gov in December 2017 did not identify any ongoing or unpublished

    trials that would likely influence this review.

    Clinical Input Received from Physician Specialty Societies and Academic

    Medical Centers

    While the various physician specialty societies and academic medical centers may provide

    appropriate reviewers who collaborate with and make recommendations during this process,

    input received does not represent an endorsement or position statement by the physician

    specialty societies or academic medical centers, unless otherwise noted.

    In response to requests, input was received from 4 academic medical centers (one of which

    provided 2 responses) and 2 specialty medical societies (one of which provided 2 responses)

    when this policy was under review in 2014, with specific focus on testing in children. There was

    consensus among reviewers that genetic testing for HP is medically necessary in children.

    Medicare National Coverage

    There is no national coverage determination (NCD). In the absence of an NCD, coverage

    decisions are left to the discretion of local Medicare carriers.

    Regulatory Status

    Clinical laboratories may develop and validate tests in-house and market them as a laboratory

    service; laboratory-developed tests (LDTs) must meet the general regulatory standards of the

    Clinical Laboratory Improvement Amendments (CLIA). Genetic testing for hereditary pancreatitis

    is available under the auspices of CLIA. Laboratories that offer LDTs must be licensed by CLIA for

    high-complexity testing. To date, the U.S. Food and Drug Administration has chosen not to

    require any regulatory review of this test.
