Two SNPs, rs2280543 from BET1L (χ<sup>2</sup> = 18.3, OR = 0.64, P = 1.87 × 10<sup>-5</sup>) and rs12484776 from TNRC6B (χ<sup>2</sup> = 19.7, OR = 1.40, P = 8.91 × 10<sup>-6</sup>), were identified as significantly associated with the disease status of UL.
Meta-analysis showed a strong association at blocked early in transport 1 homolog (BET1L) rs2280543 for intramural UFs (meta-OR = 0.51, standard error (SE) = 0.14, Q = 0.590, I = 0, p = 2.48 × 10(-6)), which is stronger than the overall association with UF risk.
