AS also have deletions in this region. However, the analysis of patients with imprinting mutations resulting in PWS or AS showed that the smallest regions of overlap for the imprinting mutations are not the same for the two groups of individuals. The IC is thus a bipartite structure with one proximal region of about 880 bp that regulates the paternal-to-maternal imprinting switch, and when disrupted may lead to AS, and another, distal 4.3-kb region that when disrupted results in PWS[14] (see Angelman Syndrome). The imprinting center deletions are also identified in the fathers of the affected individuals, and are associated with a 50% recurrence risk for subsequent pregnancies. On the other hand, the imprinting defects without identifiable IC deletions (Type IVb) are considered sporadic, and are not associated with greater recurrence risk.[13] A summary of Types I-IV is given in Table 1.

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
