Is Cold Sores Genetic

TUESDAY, Sept. 17 (HealthDay News) – A gene mutation explains why some people develop cold sores while others do not, according to a new study.

They then looked at blood samples from people with cold sores and found that one of the genes previously identified – IL28b – was mutated.

What Are Cold Sores?

They did a mathematical analysis and found that the odds of linkage from one of the six genes on chromosome 21 to cold sores stands at 2, 500: 1. That’s strong enough to indicate a connection, according to the researchers who presented their finding at the recent Infectious Disease Society of America’s annual meeting.

Both HSV-1 (which produces most cold sores) and HSV-2 (which produces most genital herpes) are ubiquitous and contagious. These genes encode a variety of proteins involved in forming the capsid, tegument and envelope of the virus, as well as controlling the replication and infectivity of the virus. The goal of our investigation was to define genes linked to cold sore frequency. SNP genotyping is a test that detects genetic make-up variations between individuals. People who get frequent flare-ups of cold sores may have variations of an obscuregene, according toa study published this weekin theJournal of Infectious Diseases. Twenty-one percent of the trait is due to genetic factors, said study author, Dr. Ever feel a little embarrassed when a cold sore flare up comes around because you’ve been told its herpes? Well, rest-easy friend because scientists are giving you a much more socially-acceptable excuse by blaming it on a genetic mutation. A genetically engineered version of a virus that normally causes cold sores shows real promise for treating skin cancer, say researchers. Fever blisters, also called cold sores, usually occur outside the mouth-on the lips, chin, cheeks or in the nostrils. Genetic studies show that susceptibility to recurrent outbreaks of the sores is inherited in some patients.

Herpes Simplex Virus

Researchers have posted excellent results from a Phase III trial, which used a genetically modified version of the virus which causes cold sores to target and kill cancer cells even in patients with inoperable tumours. If you’ve ever wondered why you always seem to get one of those pesky cold sores, new research suggests your genes might have something to do with it. But your genes could be partially to blame for cold sores, which are actually the herpes simplex 1 virus, also known as HSV-1. A new study published in the Journal of Infectious Disease found that a certain gene is responsible for 21 percent of cold sore outbreaks. Overall, around a quarter of Britons have the genetic flaw that makes them prone to cold sores, the journal PLoS Pathogens reports. Genital herpes is a sexually transmitted disease (STD) caused by a virus group that may also cause cold sores in the mouth. It is contagious and can be spread by carrierspersons who are infected with the virus but have no symptoms of the disease. Inheritance and Genetics of Cold sores including heritability, family history, and inheritance patterns. We identified a 3-megabase region on human chromosome 21 containing 6 candidate genes associated with herpes simplex labialis (HSL, cold sores). A genetically-engineered version of a virus that normally causes cold sores shows real promise for treating skin cancer, say researchers. I was searching for a forum that talks about cold sores and found this one. I’m looking for a product that works for the cold sore. Your toothbrush can harbor the virus for up to seven days and if you keep your toothbrush, you’re taking a chance of getting more cold sores. Sure it can be a hassle but better safe than sorry, right? !
