Date Time Researchers Discover New Genetic Variants Responsible for Neurodevelopmental Disorders Researchers at the Center for Applies Genomics (CAG) at Children’s Hospital of Philadelphia (CHOP) have revealed how variants of a gene responsible for packing and condensing genetic material present a novel cause for certain neurodevelopmental disorders. The findings were published today in Science Advances. Many neurodevelopmental disorders classified as intellectual disabilities are linked to certain genetic variants. Despite this, the underlying molecular mechanism for most of these patients is unknown. In particular, several neurodevelopmental disorders have been linked to pathogenic variants in genes responsible chromatin remodeling, or the rearrangement of the structure of chromosomes that allows for the transcription of DNA into directions to carry out necessary functions of the cells in the body.
