■ GNB1 Encephalopathy
◇ Context: Researchers at the Indian Institute of Technology (IIT), Madras, Tel Aviv University and Columbia University are studying a rare genetic brain disease called “GNB1 Encephalopathy” and trying to develop a drug to treat it effectively.
□ About GNB1 Encephalopathy:
◇ GNB1 Encephalopathy is a kind of neurological disorder, which affects individuals in the foetus stage.
◇ Scientists say delayed physical and mental development, intellectual disabilities, and frequent epileptic seizures, are among the early symptoms of the disease.
◇ A single nucleotide mutation in the GNB1 gene that makes one of the G-proteins, the “Gβ1 protein,” causes this disease.
◇ Children born with GNB1 mutation experience mental and physical developmental delay, epilepsy (abnormal brain activity), and movement problems.
