Scientists identify new genetic disease that delays children’s intellectual development

Scientists identify new genetic disease that delays children’s intellectual development

Scientists have identified a new genetic disease, which causes some children’s brains to develop abnormally, resulting in delayed intellectual development. The majority of patients with the condition, that is so new it doesn’t have a name yet, have severe learning difficulties which affect their quality of life. An international team of researchers from the universities … Read more

Digging Deep: Is genetic recombination linked to expression of harmful traits?

Digging Deep: Is genetic recombination linked to expression of harmful traits?

Most mammals, including humans, are diploid. That is, nuclear DNA (nrDNA) exists as pairs of chromosomes (humans have 23 pairs of chromosomes, while mice have 20). This pair of chromosomes are homologous, in that the sequence of genes on both the chromosomes is the same. However, a gene that sits on a particular address (‘locus’) … Read more

South Carolina researchers tackle health disparities using genetics

South Carolina researchers tackle health disparities using genetics

Quenton Tompkins’ family tree is deeply rooted in rural McCormick County, South Carolina. His grandfather was a sharecropper in McCormick. His mother, who turns 88 this month, grew up as the youngest of 24 children. Branches of aunts, uncles, and cousins ​​now stretch from Florida to Chicago. And although 48-year-old Tompkins has heard plenty of … Read more

Most synonymous genetic mutations are strongly harmful, study shows

Most synonymous genetic mutations are strongly harmful, study shows

In the early 1960s, University of Michigan alumnus Marshall Nirenberg and a few other scientists deciphered the genetic code of life, determining the rules by which information in DNA molecules are translated into proteins, the working parts of living cells. They identified three-letter units in DNA sequences, known as codons, that specify each of the … Read more

Researchers discover specific genetic signals in people who develop severe COVID-19

Researchers discover specific genetic signals in people who develop severe COVID-19

Researchers from the University of Sheffield and Stanford University in the US have discovered there are specific genetic signals in people who develop severe coronavirus infection. It is known that age, body mass index and pre-existing health problems account for some of the disparities, but genetics also play a significant role. This pioneering research aimed … Read more

Whole genome sequencing of 1,700-year-old individuals shows genetic heterogeneity in ancient Koreans from Gaya

Most synonymous genetic mutations are strongly harmful, study shows

An international team led by The University of Vienna and the Ulsan National Institute of Science and Technology in collaboration with the National Museum of Korea has successfully sequenced and studied the whole genome of eight 1,700-year-old individuals dated to the Three Kingdoms period of Korea (approx. 57 BC-668 AD). The first published genomes from … Read more
