ERAP1

Genetic variation of the antigen processing machinery (APM) components TAP2, LMP7, and ERAP1 is related to cervical carcinoma risk, although the relation with expression and clinical outcome remains unknown.

The location of the ERAP1-127 SNP in the peptidase M1 domain of the ERAP1 aminopeptidase suggests the possibility of direct functional consequences of variation at this locus.

 cervical peidermoid carcinoma (cervical cancer)

• Genetic variation in APM component genes, particularly ERAP1, is an important contributing factor in cervical carcinogenesis, progressive tumor growth and survival.
