Among the proteins identified, four had never previously been associated with leiomyoma: isoform 2 of guanine nucleotide-binding protein G(I)/G(S)/G(T) subunit β-1, isoform 3 of polymerase I and transcript release factor, isoform 5 of prelamin-A/C and FHL1. This evidence concerns the gene FHL1 and leiomyoma.
