ERCC2 and oculopharyngeal muscular dystrophy: In our review of 47 eligible studies, six SNPs in GSTM1 (null)[15], [16], [17], [18], CCND1 (G870A)[19], [20], MMP3 (-1171; promotor region)[21], [22], TNFα (-308; rs800629) [23], [24], XPD (codon 751)[25], [26] and Gemin3 (rs197412) [27], [28] were identified as suggestive markers for OPMD susceptibility in populations worldwide and an additional SNP in p53 (codon72) for Indian populations [29], [30].
