Disorders for CTRC Gene

(1) OMIM Diseases for CTRC Gene (601405)


  • Pancreatitis, hereditary (PCTT) [MIM:167800]: A disease characterized by pancreas inflammation, permanent destruction of the pancreatic parenchyma, maldigestion, and severe abdominal pain attacks. {ECO:0000269 PubMed:18059268, ECO:0000269 PubMed:18172691, ECO:0000269 PubMed:22580415, ECO:0000269 PubMed:22942235}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry. Loss-of-function CTRC variants predispose to pancreatitis by diminishing its protective trypsin-degrading activity (PubMed:18059268). They cause loss of function by one or more of three mechanisms: reduced secretion, catalytic defect and increased degradation by trypsin (PubMed:22942235). {ECO:0000269 PubMed:18059268, ECO:0000269 PubMed:22942235}.
