Gene symbols : the challenge

Almost certainly, one day, you'll have between your hands a list of outdated gene symbols. And you'll probably think that updating them is a straightforward task, but it's not that simple! Because there's the word 'bio' in bioinformatician, updating the gene symbols reminds me of the futile cycle. According to Wikipedia's definition, a futile cycle occurs when two metabolic pathways run simultaneously in opposite directions and have no overall effect other than to dissipate energy in the form of heat**.  Updating the [...]

Assessing enrichment

Working on a set of RNA-seq of AML patient samples, I stumble on gene X.  When its expression is high, 50% of the samples are mutated on gene Y, a mutation that has a prevalence of only 20% in the rest of the dataset.  Is there a link between these two observations?  Let's put some numbers on this:  among the 131 samples of the dataset, 28 show mutations on gene Y, 6 have high expression of X and 3 have both "features".  The table below is [...]
