Genomic imprinting is also known as Parental imprinting - when a child receives two (2) sets of chromosomes , one set from the mother, and the other from the father. The expression of the genes in each set is in accordance with the parent of origin. If the child receives both sets of chromosomes from the same parent, there will be a loss of expression of the genes of the other parent. This abnormal imprinting has been associated with several neurodevelopmental disorders.
