To validate this finding in an independent cohort, we obtained MKRN2 expression data from sperm samples (including 8 OAT patients and 13 normal subjects) of American populations which was submitted to the database of European Bioinformatics Institute (EBI) by Platts and colleagues (E-GEOD-6872)16. Here, MKRN2 is linked to thyroid gland oncocytic adenoma.
