Descriptor English: Chromosomal Position Effects
Descriptor Spanish: Efectos de la Posición Cromosómica
Descriptor efectos de la posición cromosómica
Scope note: Efectos sobre la expresión génica que dependen de la locación del gen con respecto a los genes vecinos y región del cromosoma. Los efectos de posición estables son dependientes de la secuencia. Los efectos de posición variegados dependen de si el gen está localizado o adyacente a la HETEROCROMATINA o EUCROMATINA.

Tree number(s): G05.308.203.124
RDF Unique Identifier: https://id.nlm.nih.gov/mesh/D055012
Scope note: The effects on gene expression that depend on the location of a gene with respect to its neighboring genes and region of chromosome. Stable position effects are sequence dependent. Variegated position effects depend on whether the gene is located in or adjacent to HETEROCHROMATIN or EUCHROMATIN.
