The best example of how epigenetic mechanisms can influence fetal growth are imprinting disorders such as Angelman syndrome and Beckwith–Wiedemann syndrome. A sentinel hand feature of this condition is syndactyly of … 24). By ultrasound, the sutures normally are hypoechogenic, meaning they do not return the ultrasound signal and appear as dark areas on the images.

Epigenetic modifications of the genome provide a mechanism that allows the stable propagation of gene activity states from one generation of cells to the next. Fewer studies considered the use of machine learning methods to identify defects existing in the fetal brains [ 7 , 8 ]. In each cell, there are 46 chromosomes, found in 23 matching pairs.
