GJB2 and nodular sclerosis classical Hodgkin lymphoma: In the current study, the majority of pathogenic variants of GJB2, SLC26A4 and MT-RNR1 were obtained and a primary genetic test for NSHL was designed using an SNPscan genotyping technique with the ability to simultaneously detect 115 different variants in GJB2 (n = 36), SLC26A4 (n = 77), and MT-RNR1 (n = 2), the common genes related to HL.
