Epigenopathies were introduced in an earlier post Today’s post takes another dip into the genetics of autism and currently existing therapies that could be re-purposed for autism.  We also see that many secrets remain beyond the 3% of your DNA that usually gets all the research attention.  The remaining 97% is not junk after all. There was an earlier post on this blog that introduced Epigenetics.  It is not such a complicated subject, just think about it as little tags on your DNA that turn genes on/off usually when they should not be, but there remains the possibility to use epigenetics for good.  In people with under-expression of an important gene you could “tag it” and then increase its expression. The exome is the part of your DNA that encodes the various proteins needed to build your body.  The remaining 97% of your DNA was once thought to be just junk; we saw in recent post that one part contains enhancers and silencers that control expression of the gen...

Today’s post is about epigenetics, a complex area of science, that has been touched upon in previous posts. Since none of us are experts in genetics we will focus on the application of epigenetics rather than going into the excruciating details.  Skip over any parts that get too technical. Some of the interesting studies, that are of more academic interest, I will put in a later post. Epigenetics is just one way in which gene expression (whether genes are turned on or off) can be altered.  There are other ways, which may be equally important. It is evident that epigenetics plays a role in many conditions including autism, schizophrenia, inflammation, asthma, COPD and cancer. Even based on today’s highly superficial review, there is an immediate, practical, therapeutic prospect, worthy of investigation.  Thanks to Professor Peter Barnes in London and again those irrepressible researchers in Tehran, who were actually trialing theophylline for entirely different reasons.
