Overview
Other Diagnostic Studies
Genetic testing :
- Genetic testing and genetic counselling is recommended for patients with hereditary pancreatitis.[1]
- Patients with hereditary pancreatitis who require genetic testing need to be counselled before and after the genetic testing is done.[2][1][3]
- Genetic testing is generally done for the following genes:[4]
- PRSS1
- CFTR
- SPINK1
- CTRC
In Symptomatic patients:
- Patients with any one of the following featires should be considered for genetic testing:[2][5]
- A positive history of unexplained documented episode of pancreatitis in childhood
- Idiopathic chronic pancreatitis before 25yr age
- Family history of any mutations associated with hereditary pancreatitis
- Recurrent acute attacks of pancreatitis of unknown etiology
- A positive family history of any one of the following with an unknown etiology;
- Recurrent acute pancreatitis
- Idiopathic chronic pancreatitis
- Childhood pancreatitis
In Asymptomatic patients (Predictive testing):
- Predictive testing is done only after expert genetic counseling and may be considered for patients who have a first-degree relative with a known PRSS1 mutation.[5][2]
- Predictive testing is not done for patients below 16 yr age.
- Predictive testing is usually not recommended for patients with SPINK1 or CFTR mutations.
