Two times two equals five. Some of the genetics behind mathematical capability

November 19, 2020 – Does genetic variation gives rise to differences in mathematical ability? Based on the observation that certain individuals can solve a simple mental arithmetic, such as the square root of nine, in a split second while other individuals need days to do so, one could assume that certain genes for these interindividual differences in mathematical ability could be involved.

Study looks at genetic background of healthy people who develop severe Covid-19 illness

June 13, 2020 – To help disentangle the secrets of Covid-19 disease, researchers are sequencing the DNA of young grown-ups and children who suffer from extreme Covid-19 disease ailments in spite of having no hidden clinical issues. The scientists are searching for hereditary genetic risk factors that could put certain people at high danger of getting seriously sick from the novel coronavirus,

Diagnoses for children with rare genetic diseases by 3-D facial scans

June 07, 2020 – Most children with rare genetic diseases spend years undergoing medical tests and waiting for a diagnosis—a long, exhausting process that takes its toll on children and their families. Almost half of these children never get a definitive diagnosis.

In a new and exciting development,

Host factors may influence Covid-19 severity more than viral genetic variation

May 22, 2020 – Host factors (i.e., disease phenotypes and/or predispositions) instead of viral genetic variation seem to impact more on sickness severity among Covid-19 patients, as indicated by an investigation from China. Scientists in Shanghai analyzed clinical, atomic, and immunological information from in excess of 300 individuals with affirmed Covid-19.

Besides the now approved remdesivir: Emerging options to treat Covid-19

May 03, 2020 –  The world is desperate in the search for a treatment or better yet a vaccine in the Covid-19 pandemic. Slowly, there are some options emerging at least for the treatment of seriously ill Covid-19 patients. First of all,  the American Food and Drug Administration just issued an emergency use authorization (EUA) for the investigational antiviral drug remdesivir for the treatment of suspected or laboratory-confirmed COVID-19 in adults and children hospitalized with severe disease.

Klotho’s role in some patients with Alzheimer’s disease revealed?

April 24, 2020 – The klotho gene is named after the fanciful Greek goddess of destiny Clotho who turns the string of life known to be related with longer life and improved cognizance. In modern biology, allelic variants of the klotho gene in fact have been associated with long life span.

First therapy for children with debilitating NF-1 approved in the USA

April 12, 2020 – The human genetic disease neurofibromatosis type 1 (NF-1) is a complex multi-system disorder caused by the mutation of a gene  (NF1 gene) on chromosome 17 that is responsible for production of a protein called neurofibromin which is needed for normal function in many human cell types.

Inherited mutation in ELP1 predisposes children to medulloblastoma

April 03, 2020 – Medulloblastoma is the most common malignant pediatric brain tumor. Medulloblastomas are invasive, rapidly growing tumors that, unlike most brain tumors, spread through the cerebrospinal fluid and frequently metastasize to different locations along the surface of the brain and spinal cord.

  • Gene that protects against osteoarthritis identified December 2, 2020
    Osteoarthritis is one of the most common problems associated with aging, and although there are therapies to treat the pain that results from the breakdown of the cartilage that cushions joints, there are no available therapies to modify the course of the disease.
  • Treating brain diseases now possible December 1, 2020
    Neurological diseases of the brain such as dementia, autism and schizophrenia are now a growing social problem. Nevertheless, studies on their definitive cause are still insufficient. Recently, a POSTECH research team has identified the mechanism in which such neurological diseases occur, thus solving the enigma to treating them.
  • Scientists identify new genetic MND risk factor in junk DNA December 1, 2020
    A new genetic risk factor for Motor Neurone Disease (MND), which if treated could halt or prevent the degenerative condition, has been identified in so-called 'junk DNA' by scientists at the University of Sheffield. The newly discovered genetic changes are present in up to one percent of MND patients.
  • Genomic analysis of mako shark reveals genes relating to tumor suppression in humans December 1, 2020
    Anecdotal reports claim that the incidence of cancer in sharks is very low, but there is not enough data to confirm this estimate categorically. A study published in the journal Genomics, however, presents strong evidence of anti-tumor activity in the genome of the Shortfin mako shark, Isurus oxyrinchus.
  • A large-scale tool to investigate the function of autism spectrum disorder genes November 30, 2020
    Scientists at Harvard University, the Broad Institute of MIT and Harvard, and MIT have developed a technology to investigate the function of many different genes in many different cell types at once, in a living organism. They applied the large-scale method to study dozens of genes that are associated with autism spectrum disorder, identifying how […]
