genomic imprinting

Pronunciation:(jeh-NOH-mik im-PRIN-ting)

Definition: An epigenetic process resulting in the inactivation of an allele depending on which parent it was inherited from. Genomic imprinting can have clinical relevance because it may affect the expression of a gene mutation (i.e., the phenotype) in the offspring of an affected parent depending on which parent is passing on the mutation.GeneticsHealth professional
