Finally, six proteins were found to be unique in the infertile group; these were neuroblast differentiation-associated protein (AHNAK), isoaspartyl peptidase/L-asparaginase (ASRGL1), UMP-CMP kinase (CMPK1), phosphoglucomutase-1 (PGM1), cornulin (CRNN), and suprabasin (SBSN). This evidence concerns the gene PGM1 and Infertility.
