“They found SNPs that regulate one gene (Ikaros) in different cell types, meaning they found different cis-regulatory regions for a single gene, that map to different pathways…. they used the cell-type specific information from ENCODE data.”

here are three more relevant papers about retroduplications :

Human chimp increase in segmental duplications

Sunday, September 1st, 2013

QT:”
Our results suggest that the evolutionary properties of copy-number mutation differ significantly from other forms of genetic mutation and, in contrast to the hominid slowdown of single-base-pair mutations, there has been a genomic burst of duplication activity at this period during human evolution.

This is a paper on increased rates of segmental duplications along the lineage to human and chimp.
This should have some implications for pseudogene numbers between organisms.

Analysis of 6,515 exomes reveals the recent origin of most human protein-coding variants : Nature : Nature Publishing Group

Saturday, August 31st, 2013

QT:”
We estimate that approximately 73% of all protein-coding SNVs and approximately 86% of SNVs predicted to be deleterious arose in the past 5,000–10,000 years.

Gene intolerance scores in a Plos Gen paper

Monday, August 26th, 2013

http://www.plosgenetics.org/article/info%3Adoi%2F10.1371%2Fjournal.pgen.1003709#pgen-1003709-g006
This paper discusses gene intolerance score — very similar to depletion of common polymorphisms. They don’t analyze non-coding regions — this is using exome data only. Blue for tolerant and red for intolerant (see Figure 1) .

Strict evolutionary conservation followed rapid gene loss on human and rhesus Y chromosomes.
