Genes affected
CELA2B (HGNC:29995): (chymotrypsin like elastase 2B) Elastases form a subfamily of serine proteases that hydrolyze many proteins in addition to elastin. Humans have six elastase genes which encode the structurally similar proteins elastase 1, 2, 2A, 2B, 3A, and 3B. Like most of the human elastases, elastase 2B is secreted from the pancreas as a zymogen. In other species, elastase 2B has been shown to preferentially cleave proteins after leucine, methionine, and phenylalanine residues. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2021The c.391G>A (p.V131I) alteration is located in exon 5 (coding exon 5) of the CELA2B gene. This alteration results from a G to A substitution at nucleotide position 391, causing the valine (V) at amino acid position 131 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
