From: Heritability of skewed X-inactivation in female twins is tissue-specific and associated with age

Skewed X-inactivation varies across tissues with a higher prevalence in blood than fat and skin tissues. Distribution of the degree of skewing (top row) and XISTASE (bottom row) in LCLs (n = 422 samples), whole-blood (n = 72 samples), fat (n = 378 samples) and skin (n = 336 samples) tissues. XISTASE XIST allele-specific expression.
