Lastly, 14 different non-GJB2 HL disease causing variants in 10 genes (CHD7, HDAC8, MITF, NEFL, OTOF, SF3B4, SLC26A4, TECTA, TMPRSS3, and USH2A) were found among 13 patients confirming the extreme genetic heterogeneity of hereditary HL. The gene discussed is TMPRSS3; the disease is Hodgkins lymphoma.
