SOS1 and endometriosis: The genes enriched for association with endometriosis (P < 0.05) in this pathway were (i) FN1 (fibronectin 1, P = 9.75 × 10−4); (ii) FGA (fibrinogen alpha chain, P = 1.95 × 10−3); (iii) FGB (fibrinogen beta chain; P = 3.95 × 10−3); (iv) FGG (fibrinogen gamma chain; P = 1.95 × 10−3); (v) RAP1B (Ras-related protein Rap-1b; P = 9.67 × 10−3) and (vi) SOS1 (Son of sevenless homolog 1; P = 7.50 × 10−4).
