DDRGK1 and Thrombocytopenia: Interestingly, a genome-wide association study (GWAS) study has identified one SNP (rs11697186) in DDRGK1 (same as UFBP1) gene that is strongly associated with anemia and thrombocytopenia in peggylated interferon and ribavirin therapy for chronic hepatitis C patients, which provides clinical evidence for possible involvement of UFBP1 in regulation of erythropoiesis [14].
