We are living in an era of extremely fast developing advancements in the field of genetics. With the completion of full genome mapping, there has been a race to improve our understanding of human genetics.
Approximately 75% of individuals with a clinical diagnosis of Kabuki are caused by an MLL2 mutation. According to a study published in July 2011 the presenting characteristics of MLL2 mutation-positive cases did not differ greatly from the MLL2 mutation-negative cases. the one exception being that renal anomalies were more common in the mutation-positive group.
The human body has many different
cells yet they all share identical information content. The human genome (the
book of life), which is the encyclopedia of all the machinery in all the cells
has about 20000 genes (words). How does a cell decide which genes (words) to
use at a specific time? One way is through the use of epigenetics. Epigenetic
modifications sit close to the genes (words) they affect and thereby
essentially highlight (or strikethrough) the genes (words) that should be used
by that cell type at that time.
