With the exception of a weak association between the BMP4 tagging SNP rs2761884 and the combined patient group HTG+OHT that did not withstand permutation testing (uncorrected p=0.0400, corrected p=0.1320), no associations (p<0.05) were identified between the patient groups (HTG and OHT) and FOXC1, TGFβ2, and BMP4 alleles and haplotypes compared to the control group.
