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.

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.

Are Asians at higher genetic risk of serious adverse events to common medications?

March 10, 2020 – A widespread assumption is, the people of Asian descent are more prone to serious, sometimes deadly adverse drug reactions, even when taking rather common medications prescribed for gout through to depression. In the ages of genetics and precision medicine, the question then comes up if Asian people could be at such heightened risk because of underlying particular genetic factors.
