A study in South Korea failed to find associations of EGFR single-nucleotide polymorphisms (SNPs) 151904 A>T, 162093 G>A, or 181946 C>T with advanced endometriosis.[11] A similar lack of association was reported for the polymorphisms Egfr+2073 A/T and Egf+61 G/A and risk of endometriosis in a Japanese population.[12] However, a study found evidence of an association of T-containing genotypes and alleles at the EGFR single-nucleotide polymorphism (SNP) 2073∗ with greater risk of endometriosis and leiomyoma.[13]. Here, EGFR is linked to leiomyoma.
