Imprinted Genes with Aberrant DNA Methylation.

Note: E = parent with expressed allele; # = number of significantly altered loci in low motility samples; MS = methylation status of the loci; M = maternally expressed; P = paternally expressed; N = parent of origin not determined; − = loci hypomethylated in low motility samples; + = loci hypermethylated in low motility samples; −/+ = more than two loci were altered and some of the loci were hypomethylated and some of were hypermethylated. Genes with * have been previously reported differentially methylated in sperm.
