‘Telepathic’ genes

 
New research has shown evidence that genes have the ability to recognize similarities in each other from a distance, without any proteins or other biological molecules aiding the process. This discovery could explain how similar genes find each other and group together in order to perform key processes involved in the evolution of species.
According to […]

GEN2PHEN web based project to capture health & disease genetic knowledge

The EU funded GEN2PHEN project plans to internationally orchestrate the electronic gathering and use of data that show how gene sequences (’genotypes’) contribute to individual differences in disease, drug response, and other characteristics (’phenotypes’). These relationships (usually in the form of “genotype-phenotype” information stored in scattered databases) are deemed to become essential for future prognosis, […]

Human-animal embryo hybrid testing given go ahead in UK

Early embryos yield stem cells,(photo courtesy of BBC news www.bbc.co.uk/news) 
The Uk’s fertility regulator Human Fertilisation and Embryology Authority (HFEA) has given the green light to two teams of scientists for the creation of hybrid human-animal embryos.
Scientists, research institutions and patient groups have challenged the UK government for much of the last year: the Department of Health wanted […]

b5’s Kids Health Notes and Autism Vox - CNTNAP2 implicated in autism

Grace at Kids Health Notes and Kristina at Autism Vox have both written about the gene CNTNAP2 being unequivocally implicated in Type 1 Autism.
In her article CNTNAP2, an autism susceptibility gene which I highly recommend,  Kristina writes a personal account of her ongoing experience with her son Charlie’s autism and discusses the recent research findings.
Do read […]

Great genetics based article on Autism at b5’s Autism Vox

My colleague Kristina at Autism Vox has written a great article about the genetic basis of Autism.  Research has indicated that either a deletion or a duplication of a section of chromosome 16 seems to contribute strongly to susceptibility to autism.
I highly recommend you click on the following link to read more:

Breast cancer risk varies amongst BRCA gene carriers

 
Breast awareness and regular checking are important in early detection of breast cancer
Further to my articles on the BRCA breast cancer genes, an American and Danish study has found the risk of developing cancer amongst carriers of the BRCA1 and 2 breast cancer gene mutations varies greatly.  The risk of breast cancer in BRCA1 and […]

Down’s Syndrome gene may protect against cancer

 
 Male Down’s Syndrome with trisome at chromosome 21
People with Down’s Syndrome are less likey to get solid tumor cancers, research from Johns Hopkins University has revealed.
Up to 95% of Down’s syndrome cases are caused by “trisomy 21″, in which the baby has three, rather than two, copies of chromosome 21, and the hundreds of genes it […]

New fertility technique allows boys born with extra X chromosome (Klinefelter’s) to become fathers

     
Klinefelter’s Syndrome
Almost one in every 500-1,000 males babies are born with an extra X chromosome.  This condition is known as Klinefelter’s Syndrome. These men are also known as XXY males or 47XXY males.
Klinefelter’s syndrome is a condition that occurs in men who have an extra X chromosome in most of their cells. The syndrome can affect different […]
