APOM and type 2 diabetes mellitus: Unfortunately, the lowing of plasma apoM levels of -C724del mutant allele carriers compared to the wide-type homozygotes carriers in T2DM patients was not statistically different (18.20 ± 8.53 ng/uL vs 20.44 ± 10.21 ng/uL, P = 0.245) in present study, so further researchs were needed by enlarging the sample.
