Skewed x linked inactivation
Webb1 dec. 2024 · Female somatic X-chromosome inactivation (XCI) balances the X-linked transcriptional dosages between the sexes, randomly silencing the maternal or paternal X chromosome in each cell of 46,XX females. WebbOverview: At a certain point in development, females no longer require gene expression from both X chromosomes. Typically, one X chromosome is randomly selected to be silenced. When silencing is non-random, X-inactivation is skewed. Females with skewed X-inactivation and a pathogenic mutation in an expressed X-linked gene can develop X …
