Because these genes are carried on the X-chromosome, they are subject to a process known as X-chromosomeinactivation.
由于这些基因存在于X染色体上,它们发生了X染色体失活的处理。

This phenomenon is mostly seen in imprinted genes and X-chromosomeinactivation where DNA methylation of promoter regions leads to repression of gene expression.
To assess the clonal origin of renal clear cell carcinomas by the study of X-chromosomeinactivation pattern in female clear cell renal carcinomas and normal renal tissues.
