Nasal glial heterotopia Nasal glial heterotopia Nasal glial heterotopia refers to congenital malformations of displaced normal, mature glial tissue, which are no longer in continuity with an intracranial component. This is distinctly different from an encephalocele, which is a herniation of brain tissue and/or leptomeninges, that develops through a defect in the skull, where there is a continuity with the cranial cavity. While nasal glial heterotopia (NGH) is the preferred term, synonyms have included nasal glioma. However, this term is to be discouraged, as it implies a neoplasm or tumor, which it is not. By definition, nasal glial heterotopia is a specific type
Human germline engineering Human germline engineering Human germline engineering is the process by which the genome of an individual is edited in such a way that the change is heritable. This is achieved through genetic alterations within the germinal cells, or the reproductive cells, such as the oocyte and spermatogonium. Human germline engineering should not be confused with gene therapy. Gene therapy consists of altering somatic cells, which are all cells in the body that are not involved in reproduction. While gene therapy does change the genome of the targeted cells, these cells are not within the germline, so the alterations are not
