Genetic Architecture of Grey Matter - A Review

Abstract

Genetic architecture explains about characteristics of different types of genetic variants which affect the traits for heritable variability. The present review is to document the deeper understanding of the genetic architecture of grey matter obtained from reliable sources of information which are associated with grey matter density and volume, cortical thickness, surface area, genetic variants, genetic heritability and genetic effects including Alzheimer disease, Huntington disease and some various diseases. The literature search on genetic architecture was carried out for papers published by google scholar and PubMed with the intention of retrieving all original reports that were relevant to it. The quality assessment of selected studies was conducted for 77 collected articles. This review is an attempt to update recent advances and provide a deeper understanding of the genetic architecture of grey matter which benefits scientists and geneticists.
