Single nucleotide polymorphism (SNP) analysis demonstrates a significant association of tumour necrosis factor-alpha (TNFA) with primary immune thrombocytopenia among Caucasian adults
T-helper 1 polarization in patients with primary immune thrombocytopenia (ITP) is well documented. However, the genetic contribution to this imbalance remains unclear. To address this question, we selected six candidate single nucleotide polymorphisms within cytokine or cytokine receptor genes for association testing among Caucasian adults. Patients from the United Kingdom Adult ITP Registry were
