Genes affected

CELA1 (HGNC:3308): (chymotrypsin like elastase 1) 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. Unlike other elastases, pancreatic elastase 1 is not expressed in the pancreas. To date, elastase 1 expression has only been detected in skin keratinocytes. Clinical literature that describes human elastase 1 activity in the pancreas or fecal material is actually referring to chymotrypsin-like elastase family, member 3B. [provided by RefSeq, May 2009]

Ambry Genetics

Jul 13, 2021

The c.265T>C (p.Y89H) alteration is located in exon 4 (coding exon 4) of the CELA1 gene. This alteration results from a T to C substitution at nucleotide position 265, causing the tyrosine (Y) at amino acid position 89 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
