I will write a separate blog about several of these topics individually, but below are some interesting points about genetics.<\/p>\n<ul>\n<li>The human genome contains 3.2 billion (!!) base pairs, or chemical nucleotides.<\/li>\n<li>There are approximately 25,000-30,000 human genes, which are the smallest units of &#8220;instructions&#8221;.<\/li>\n<li>99.9% of the human genome sequence is the same!<\/li>\n<li>Genetic variation can often arises from what is called a SNP (&#8220;snip&#8221;), a single nucleotide polymorphism. One nucleotide change within a gene can result in no discernible change, or can result in a change in phenotype (an observable trait, characteristic, shape, etc&#8230;)<\/li>\n<li>Tooth development, or odontogenesis, involves over 300 genes.<\/li>\n<li>Sporadic changes, or snips, in the genome can cause dental agenisis (failure to develop, or missing teeth), or a change in the size or number of teeth.<\/li>\n<li>About 2-9% of the U.S. population has hypodontia, or teeth that are developmentally missing.<\/li>\n<li>Genes such as AXIN2 and PAX9 have been identified as genes that can contribute to a family history of teeth that are missing.<\/li>\n<\/ul>\n<p>I will follow up with an article on the genetic influence on obstructive sleep apnea,\u00a0and its ramifications on orthodontic treatment.<\/p>\n<p><strong><em>Dr, Dan Rejman is a Board Certified Orthodontic Specialist.
