http://en.wikipedia.org/wiki/International_HapMap_Project
HapMap计划,目的是描绘人类基因多样性分布规律,研究人类基因的不同变型对人类健
康、疾病和适应能力的影响。
这个项目成果发表在《自然》等顶级科学杂志上,比如这篇2007年的:
Genome-wide detection and characterization of positive selection in human
populations.

SAN DIEGO, CALIFORNIA--Whether you have a poker-straight black mane
or frizzy blond locks, your hair depends on your ancestry. Now
researchers have come closer to figuring out just how hair traits are
passed down. According to a talk presented here last week at the annual
meeting of the American Society of Human Genetics, a single genetic
variant may explain why East Asians have thicker hair fibers than other
populations. The discovery ... 阅读全帖

攒人品,顺便回答一下 iiiir 的问题。
我们尝试过好几种不同的SNP calling的方法,包括GATK, Samtools, Varscan,
SeqGenes, 等,并且做了SNP array 作为gold standard比较各种方法的prediction
power。
从我们的经验,BWA + GATK 最好,sensitivity 和 specificity 都在95%以上。

Blinded by Big Science: The lesson I learned from ENCODE is that projects
like ENCODE are not a good idea
By Michael Eisen | Published: September 10, 2012
When the draft sequence of the human genome was finished in 2001, the
accomplishment was heralded as marking the dawn of the age of “big biology
”. The high-throughput techniques and automation developed to sequence DNA
on a massive scale would be wielded to generate not just genomes, but

由中科院上海生命科学研究院、北京基因组研究所、中国水稻研究所等单位合作的研究成果《水稻地方品种重要农艺性状相关基因的全基因组关联分析》,日前在线发表在《自然―遗传学》(Nature Genetics)杂志上。
该研究报道了中国水稻地方品种的全基因组的遗传多态性和单倍体型图谱,并对籼稻品种的14个重要农艺性状进行了全基因组关联分析,确定了这些农艺性状相关的候选基因位点,对水稻的遗传学研究和分子育种提供了重要资源。
论文一经发表,便迅速引起了世界同行的关注,许多人称之为作物遗传学研究中里程碑式的工作。
《自然―遗传学》副主编Pamela Colosimo介绍,这篇论文从编辑部到同行专家评议都获得了高度评价,是她在该杂志遇到的发表最为顺利的一篇论文。中科院副院长李家洋也对研究团队的成果表达了高度赞赏。
功不可没的GWAS
全基因组关联研究(Genome-wide Association Study,简称GWAS)是一种用来寻找基因变异与表型之间关系的遗传学方法,最近几年在人类医学遗传学领域中发展迅速。
以常见人类遗传疾病的GWAS为例,研究者首先要选取一个较大的人群样本,考察哪些是患者,然后... 阅读全帖

haploview虽然能给出一些risk haplotype, 但是老板让我作功能相关的研究,验证这
些结果,非常挠头,不知道从哪里下手,有人跟我说,针对p值高的分析一些dna 蛋白
结合,EMSA, 但是我感觉很多SNPs都很难说,有点瞎猫碰死耗子的感觉。
老板一心想深入下去,而且还在作进一步的sequencing,并且给我很多比hapmap和
1000genom project 里面更全的genotypes data。 弄得我都不知道怎么利用这些东西
了。

any comments?
http://www.nature.com/news/2011/110519/full/news.2011.304.html#
All science students learn the 'central dogma' of molecular biology: that
the sequence of bases encoded in DNA determines the sequence of amino acids
that makes up the corresponding proteins. But now researchers suggest that
human cells may complicate this tidy picture by making many proteins that do
not match their underlying DNA sequences.

hg18 hg 19的区别
Why are some variants mapped to hg18 but not hg19?
When the variation data was mapped to hg19, we did our best to come up with
a process that would result in a low error rate, while maximizing the number
of variants kept in hg19. Due to changes in the underlying assembly, some
regions are re-arranged while others contain novel sequence, thus changing
the structure of the region. In most cases the assembly hasn't changed
enough to cause difficultly in remapping,... 阅读全帖
