Genes affected

CTRC (HGNC:2523): (chymotrypsin C) This gene encodes a member of the peptidase S1 family. The encoded protein is a serum calcium-decreasing factor that has chymotrypsin-like protease activity. Alternatively spliced transcript variants have been observed, but their full-length nature has not been determined. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.-1C>T variant is located in the 5' untranslated region (5’ UTR) of the CTRC gene. This variant results from a C to T substitution 1 bases upstream from the first translated codon. This alteration was detected in one individual with chronic pancreatitis; however, clinical details were limited (Zhou J et al. J Gastroenterol Hepatol, 2011 Aug;26:1238-46). Based on nucleotide sequence alignment, this nucleotide position is well conserved in available vertebrate species. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
