Genes of Your Uncle or Aunt May Decide Your Longevity, Says Study

The study has led us to be far stricter in selecting the people in whom you have to look for those genes, the researchers said

The key to longevity can probably be found in the genes of your long-living uncles and aunts and not just parents, finds a study.

Researchers, from Netherlands’ Leiden University and US’ University of Utah, showed that an individual’s chances of dying is reduced, even if the parents themselves did not live to be extremely old, but aunts and uncles are among the top survivors in the family.

Top survivors refers to people in the top 10 per cent age-wise of a group of people born in a family within a given time period.

“We observed the more long-lived relatives you have, the lower your hazard of dying at any point in life,” said lead author Niels van den Berg, doctoral student at Leiden University in the Netherlands.

“Longevity is heritable, but that primarily applies to persons from families where multiple members are among the top 10 per cent survivors of their birth cohort. The key to a long life can probably be found in the genes of these families,” said the paper published in the journal Nature Communications.

For the study, the team analysed the genealogies of nearly 314,819 people from over 20,360 families.

The search for genes associated with human longevity has been ongoing for a long time but those genes turned out to be much more difficult to discover than genes for diseases.

The study has led us to be far stricter in selecting the people in whom you have to look for those genes, the researchers said.

According to Ken Smith, Professor at Utah, the findings underscore the importance of constructing high-quality family trees that “allow us to observe complete life-spans of individuals over generations and in diverse locations. (IANS)

Researchers Identify Gene Linked to Obesity in Children

Approximately 70 per cent of the human population carries at least one variant of this polymorphism, which is associated with an increased risk of obesity

Researchers have identified a common gene variant that increases the risk of obesity in children.
In a study published in Obesity journal, the researchers from University of Columbia found that a specific variant (single nucleotide polymorphism) of a gene called “FTO” affects eating behaviour that may be predictive of subsequent weight gain in children, who are at obesity risk.
“Early identification of the physiology and behaviours that constitute early risk factors for subsequent weight gain will help inform best practices for intervention and prevention of obesity in children,” said study author Michael Rosenbaum, a professor at Columbia University.
“This study shows that even before the development of an obese phenotype, children at risk, in this case by virtue of a common genetic variant, exhibit increased food intake,” added Rosenbaum.
For the study, the researchers included 122 children in the 5-10 year age group.

The study discovered that children who are at risk of obesity due to this genetic variant had an increased calorie intake which may contribute to gaining excess weight.
“Even though 65 calories is not a lot per se, if this pattern generalized to multiple meals per week or day, this increased caloric intake can add up over time and may contribute to gaining excess weight,” said Rosenbaum.
According to the researchers, the report could be used to further study children at obesity risk for other reasons.
“The ultimate goal is to prevent the at-risk child or the child who has obesity from becoming an adult with obesity,” added Rosenbaum.
