Although many people refer to the rotator cuff as a general area in the shoulder, your rotator cuff itself is a group of 4 tendons located at the top of your humerus. These tendons are called the subscapularis tendon, the supraspinatus tendon, the infraspinatus tendon, and the teres minor tendon.lthough many people refer to the rotator cuff as a general area in the shoulder, your rotator cuff itself is a group of 4 tendons located at the top of your humerus.

Genomic imprinting is the epigenetic phenomenon by which certain genes are expressed in a parent-of-origin-specific manner. If the allele inherited from the father is imprinted, it is thereby silenced, and only the allele from the mother is expressed.f the allele from the mother is imprinted, then only the allele from the father is expressed. Forms of genomic imprinting have been demonstrated in fungi, plants and animals.
Genomic imprinting is an example of epigenetic inheritance in which differences in gene function depend on whether the allele was inherited from the mother or father. Many disorders appear to involve epigenetic alterations to imprinted genes. Genes involved in imprinting play important roles in both preâ and postânatal growth and neurodevelopment. Imprinting disorders include several childhood genetic disorders such as PraderâWilli, Angelman and BeckwithâWiedemann syndromes, as well as several types of cancer including Wilms tumour. Recent evidence suggests a correlation between assisted reproductive technologies (ART) and imprinting disorders, a phenomenon requiring more inâdepth studies as the prevalence of ART is increasing.
