Casamento e... Genes?

Citando:
"the OXTR gene has been linked with physiological responses to social support and traits believed to be critical to support processes, like empathy. Considered alongside findings that the quality of social support is a major determinant of overall marital quality, the evidence implied that variations on the OXTR gene could be tethered to later marital quality by influencing how partners support each other. To test this hypothesis, I pulled together a multidisciplinary team of scientists including psychologists with additional expertise in marital research, a geneticist and a neuroendocrinologist specializing in oxytocin."

Estudo sobre genes e sono

https://www.thesun.co.uk/news/8306330/depression-schizophrenia-risk-increase-night-owl/

Citando:
"They identified 351 genetic variations linked to being a “morning lark” or “night owl”.

Those with the most “night” variations were programmed to wake up to 25 minutes later.

And they were more likely to suffer frommental health issues.

But the boffins found no link between these genetic variations, sleep duration and sleep quality.

They also made no difference to the risk of developing type 2 diabetes or obesity.

Eye opening

It is thought the genes affect the effectiveness of the retina, which reacts to sunlight and “resets” the body clock each day."

Gebes associados a regeneração do coração?

Citando:
"Para realizar a pesquisa, a equipe de Mommersteeg estudou dois tipos de peixes tetra mexicanos: aqueles que vivem nos rios e têm a capacidade de autorregenerar o coração e aqueles que viveram nas cavernas há cerca de 1,5 milhão de anos atrás e, com a evolução, perderam essa habilidade.

Ao compararem os dois tipos de peixe, os pesquisadores descobriram que dois genes (lrrc10 e caveolina) se tornavam muito mais ativos nos peixes de rio após uma lesão cardíaca.'

Longevidade e genes?

Nem tanto:

Citando:
"It turns out that through every generation, people are much more likely to select mates with similar lifespans than random chance would predict. The phenomenon, called “assortative mating,” could be based on genetics, or sociocultural traits, or both. For example, you might choose a partner who also has curly hair, and if the curly-haired trait winds up being somehow associated with long lifespans, this would inflate estimates of lifespan heritability passed on to your kids. Same thing for non-genetic traits like wealth, education, and access to good health care. People tend to choose partners in their same income bracket with the same terminal degree, both of which are associated with living longer, healthier lives.

The first hint that something other than genetics or a shared family environment might be at work came when Ruby tried looking at in-law relatives."

Genes e listeriose

https://observador.pt/2018/07/27/descoberto-gene-que-controla-infecao-alimentar-mais-mortifera-da-europa/

Citando:
"Neste estudo, que deu origem a um artigo publicado na revista académica Nucleic Acids Research, a equipa descobriu que é o gene denominado MouR que determina a patogenicidade da bactéria ‘Listeria monocytogenes’, responsável por causar a listeriose. Este gene é responsável por “uma adaptação radical da bactéria” ao organismo que, além de desencadear um conjunto de mecanismos que lhes permite enganar o sistema imunológico e estimular a capacidade proliferativa da bactéria, tem a capacidade de formar biofilmes no trato intestinal humano."

287 mutações em cerca de 100 genes (herdados da mãe) associadas a calvície severa

Mais sobre a calvície, e como para a altura, a coisa é mais complicada que parece:

Citando:
"The researchers then analyzed participants' genomes, looking for genetic variations, known as single-nucleotide polymorphisms, or SNPs, that were linked with severe hair loss. That search revealed 287 genetic variations, located on more than 100 genes, that were linked with severe hair loss.

Many of the genetic variations were located on or near genes that have previously been linked with hair growth, hair graying or the biological structures involved in making hair, the researchers said.

Forty of the genetic variations were located on the X chromosome, which men inherit from their mothers, the researchers said. One of the genes on the X chromosome — the gene for the androgen receptor, which binds to the hormone testosterone — was strongly linked with severe hair loss. Previous studies have also pinpointed this gene as tied to male pattern baldness.

The researchers then created a formula, which resulted in a genetic "risk score," to try to predict the chances of severe hair loss in the men."

Mais de 700 genes podem estar envolvidos na definição da altura

Citando:
"When scientists first read out the human genome 15 years ago, there were high hopes that we'd soon understand how traits like height are inherited. It hasn't been easy. A huge effort to find height-related genes so far only explains a fraction of this trait.
Now scientists say they've made some more headway. And the effort is not just useful for understanding how genes determine height, but how they're involved in driving many other human traits."

Há genes da depressão?

A depressão é genética ou deriva de factores ambientais? Provavelmente é uma mistura dos dois. E nem todas as depressões são iguais, assim como o cancro é um nome comum para várias doenças (tipos de cancro), o que torna a resposta à questão especialmente complexa:
http://www.independent.co.uk/life-style/health-and-families/healthy-living/why-is-there-no-gene-for-depression-a7291016.html


Citando:
"So is there a gene for depression? No, there isn’t. We don’t have genes for diseases, we have genes that encode proteins that serve functions in cells. So does that mean if your DNA has the relevant change in your LHPP or SIRT1 genes that you are going to develop depression? No, it probably means you may have an increased risk to develop depression depending on the environment you experience.
In the same way that we think about heart disease, cancer, obesity as having multiple “susceptibility genes”, the same is probably true for depression. "

Should You Get Tested for the Breast Cancer Genes? - Scientific American

Should You Get Tested for the Breast Cancer Genes? - Scientific American



Citando:

"The mostly common involved and most familiar breast cancer genes are the BRCA-1 and BRCA-2 genes. This sort of gene testing can be performed on blood, saliva, or even cheek swabbing.  The challenge? Hundreds of genes involving these two mutations have been discovered. Therefore, obtaining a complete test for all involved possibilities can cost up to 4,000 dollars. If patients meet certain criteria, however, insurance may cover up to 90% of the testing cost. What may be less costly and more simple, however, is if you already have an identified gene in another relative, in which testing can be more targeted and therefore much less costly."
