Genes affected

CELA2A (HGNC:24609): (chymotrypsin like elastase 2A) 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 2A is secreted from the pancreas as a zymogen. In other species, elastase 2A has been shown to preferentially cleave proteins after leucine, methionine, and phenylalanine residues. [provided by RefSeq, May 2009]

Collection Method: clinical testing

The c.568G>A (p.A190T) alteration is located in exon 6 (coding exon 6) of the CELA2A gene. This alteration results from a G to A substitution at nucleotide position 568, causing the alanine (A) at amino acid position 190 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
