Genes affected
CTRL (HGNC:2524): (chymotrypsin like) This gene encodes a serine-type endopeptidase with chymotrypsin- and elastase-2-like activities. The gene encoding this zymogen is expressed specifically in the pancreas and likely functions as a digestive enzyme. [provided by RefSeq, Sep 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 15, 2024The c.724C>T (p.R242C) alteration is located in exon 7 (coding exon 7) of the CTRL gene. This alteration results from a C to T substitution at nucleotide position 724, causing the arginine (R) at amino acid position 242 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
