WebH19 is a gene for a long noncoding RNA, found in humans and elsewhere.H19 has a role in the negative regulation (or limiting) of body weight and cell proliferation. This gene also has a role in the formation of some cancers and in the regulation of gene expression. .. The H19 gene is expressed exclusively on one parental allele in a phenomenon known as imprinting. WebIgf2 (insulin-like growth factor 2) and H19 genes are imprinted in mammals; they are expressed unevenly from the two parental alleles. Igf2 is a growth factor expressed in most normal tissues, solely from the paternal allele. H19 gene is transcribed (but not translated to a protein) from the materna …
