In addition, we think that two variants in the GATA6 promoter region (rs1416421760, MAF: A = 0.000023; rs1040912117, MAF: T = 0.000043) and one variant in the TBX3 promoter region (rs968910973, MAF: A = 0.00004), all with minor allele frequencies (MAF) of less than 1%, may play a regulatory role in GATA6 and TBX3 expression levels in patients with IIH. Here, TBX3 is linked to pseudotumor cerebri.
