Genomic imprinting: parental influence on the genome

WitrynaLike Ipl, Tih1 is a small gene with a single small intron. Tih1 maps to distal mouse Chr 1 and human Chr 1q31, chromosomal regions that have not shown evidence for imprinting and, in contrast to Ipl, Tih1 is expressed equally from both parental alleles. Ipl, Tih1, and TDAG51 have overlapping but distinct patterns of expression. Witryna6 sie 2024 · Imprinted genes have many notable features that set them apart from the vast majority of the genome.
