Low-frequency coding variants (LFCVs) in growth differentiation factor 9 (GDF9) identified by DNA sequencing in samples from mothers of dizygotic twins. The locations of LFCVs significantly associated with twinning are shown together with the minor allele frequency (MAF) in cases (Ca) and the P-value for association. The c.393insT LFCV was not tested (NT) in the full sample (Palmer et al., 2006).
