DDRGK1 and acute promyelocytic leukemia: Translocations in regions near the DDRGK1 gene on chromosome 20p13 have been found to be associated with acute myeloblastic leukemia and acute promyelocytic leukemia [13], [14], and a recent genome-wide association study identified one SNP (rs11697186) located in the DDRGK1 gene that showed strong associations in the minor-allele-dominant model with the decrease in platelet counts that occurs in response to pegylated interferon and ribavirin therapy for chronic hepatitis C [15].
