... Both distributions have a Zipfian shape, which means that few SFs occur very frequently in MEDLINE, and many SFs occur rarely. There are 24,393 human genes in Locuslink, of which 12,533 (51.4%) have at least two symbols (or synonyms). 16,828 genes have a matching LF. Of these genes, 5,812 (34.5%) ha ...

Imprinting evolution and the price of silence
... Other than typical sequence polymorphisms that do not correlate with imprint status, the nucleotide sequence of the two alleles of imprinted genes are identical. Therefore, the imprint marks that distinguish the two parental alleles must be epigenetic in nature. Epigenetic alterations are defined as ...
