Genes affected

ERAP2 (HGNC:29499): (endoplasmic reticulum aminopeptidase 2) This gene encodes a zinc metalloaminopeptidase of the M1 protease family that resides in the endoplasmic reticulum and functions in N-terminal trimming antigenic epitopes for presentation by major histocompatibility complex (MHC) class I molecules. Certain mutations in this gene are associated with the inflammatory arthritis syndrome ankylosing spondylitis and pre-eclampsia. This gene is located adjacent to a closely related aminopeptidase gene on chromosome 5. [provided by RefSeq, Jul 2016]

Feb 28, 2023

The c.769G>A (p.V257I) alteration is located in exon 4 (coding exon 3) of the ERAP2 gene. This alteration results from a G to A substitution at nucleotide position 769, causing the valine (V) at amino acid position 257 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
