We need to leverage our current knowledge to deliver actionable results to regular people. Data generation is pretty reasonable from the standpoint of time and costs, data storage who owns it, has rights to it, and how to deliver incites from that data to regular providers (see family practitioners) that aren't deeply knowledgeable about genomics and their interpretation.

The problem to tackle, IMO, is medical privacy and intellectual property. We've created a system where the only sane way for a biomedical company to behave is to patent, copyright, and hide as much medical information as possible. Further, we've made it REALLY hard to share such medical data in the first place. Now, I get WHY we do this. There are a lot of good reasons (privacy and insurance issues come to the top of my mind). However, we should be working to eliminate those reasons as much as possible. What we need to advance human understanding of medicine is a national database of medical data that's publicly available. Ideally, We'd record every measurable aspect about a person in this database and update it throughout their lives (when did they get vaccinated? What allergies do they have? Did they get any cancers?) That sort of a database would make it really easy to start mining for treatments, correlations, etc. It'd even have some positive benefits like removing the need for every doctors visit giving you a form with 50000 questions you've answered a million times before. But I get why we don't do this. We don't do this for fear of police overly relying on genetic information to "prove" someone committed a crime (We found your DNA at the scene, you must be guilty). We don't do this out of fear of Insurance companies exploding their rates when any sort of marker comes up (Oh, you've got Gene XYZ that means you'll probably die sooner, so you get a higher rate or we won't insure you). We don't do this because of issues around discrimination (Oh, you have (had?) HIV? You must be gay and we hate gay people here). But, man, do I wish we could somehow shape society so some day we could do it. It'd have the potential for so much good.

One thing that surprisingly hasn't happened in the 30 years since the Human Genome Project is a Nobel Prize for the work. There are examples from large physics projects where the leaders were awarded the prize. Surely Francis Collins and perhaps Craig Venter are deserving.
- jdale27 6y ago
  Francis Collins and Craig Venter certainly got a lot of the publicity, but arguably there are others who were more influential. E.g. Leroy Hood who developed the first automated DNA sequencer, and Mike Hunkapiller who led the commercial development of the technology at Applied Biosystems to the point where it was practical to sequence the whole genome. Hunkapiller was also the impetus behind the formation of Celera, though Venter was its leader.

Shockingly the human genome itself has not been fully sequenced, despite the human genome project completing years ago [0]. There are difficult to map regions of the genome, some of which are interesting. Only recent advances in long read sequencers have helped to solve some of these issues [1]. For the future to truly be amazing with one sequencing the lab prep, chemistry, and equipment required needs to advance. Oxford Nanopore has some advancements here [2] but it's still a ways to go before you could have a sample prepared as easily as an ultrasound or x-ray.

  The Telomere-to-Telomere consortium has made fantastic progress on this in the last year or two: https://genomeinformatics.github.io/CHM13v1/ https://genomeinformatics.github.io/CHM13v1/ Thanks to them we now have a nearly completed genome, only missing the deconvoluted rDNA array segments (~12mb or so, we know the sequences since they’re basically identical but no one has accurately placed the individual array variants yet).

  I wonder what if genes are only like "functions" and inputs still come from environment. This makes it easy to not change that function often as the output changes based on input received from the environment. While only in very rare cases the function itself needs to be modified or simply put inside another function to give the function inside access to more environmental inputs.

There was an interesting comment made on the recent "Bio Eats World" episode [0] that genetic tests are not aligned with health care reimbursement cycles. Jorge Conda [0] cited two reasons that genome sequencing (Different from 23andMe's GWAS, for example). First he cited the high upfront cost to buy the machines (Usually meaning you need to be a big hospital). The second fact was a bit more interesting, which is that doing one expensive test (Genome sequencing) which then your health care provider could do cheap queries against ("Which other users have your symptoms and similar mutations in key genes" for example) does not align with the current billing model. I think that's the "What's next". Finding a way to effectively bring genomic care to the general population, to allow for better research into genetic conditions. If you're interested in how "big" this can be, here's a case where "This American Life" covered how just a few genetic differences was the difference between an olympic athlete and a muscular dystrophy patient [2]. There's also the bio-terrorism and pandemic response angle, which is why the DoD is investing in third-generation sequencing systems where portability has finally become more of a priority.

  There are a handful of sequencing-based genetic tests that have achieved fairly wide penetration; NIPT and cancer panels are probably the best examples. However, if the question is why whole-genome sequencing has not gained wider clinical usage, I think the answer is less about reimbursement, and more the fact that there are just very few clinically compelling reasons to sequence a whole human genome. Then there is the fact that although we have ostensibly achieved the fabled "$1000 whole genome" that was touted as the tipping point for clinical acceptance, that was really more of a publicity stunt by Illumina. In reality a clinical-grade WGS still costs a multiple of $1000 (see, e.g., https://bmchealthservres.biomedcentral.com/articles/10.1186/s12913-020-05318-y https://bmchealthservres.biomedcentral.com/articles/10.1186/...). The Moore's Law-like cost reductions of genome sequencing are a bit of a myth at the present time; in practice Illumina has a monopoly on the technology used for clinical WGS, and therefore they have a great deal of influence over the effective cost of sequencing.

  > Is it possible to get my sequence from one of the commercial groups doing this, and then "look it up" in a genome reference to verify my brown eyes, for example? Yes and no. Brown eyes aren't controlled by a single gene, so it's not straightforward to look this up from your genome profile. What genome profiling companies will do is assay a finite number of specific locations on your DNA (SNPs), to get good comparison points with other people, and then predict what colour your eyes are based on which SNPs are significant for eye colour. It's not guaranteed to be right, then - nor is it guaranteed that the significant SNPs are linked to relevant genes.

It's really unclear what's next for the HGP. While HGP and many other sequencing projects have been invaluable to academic research, and it's truly useful for a number of diseases, the main result of the HGP, in my mind, is that it made clear to everybody how much harder the genotype->phenotype problem was than what the geneticists who set up the HGP anticipated. Medically speaking, there isn't enough evidence to support the cost of doing WGS for individuals in most circumstances, or even storing large amounts of WGSs to do large-scale population-level analysis.
- haihaibye 6y ago
  The HGP likely sped up the COVID vaccine - by making DNA sequencers and printers cheap. Viral genomes are typically obtained by taking a swab from a human, mapping the reads to the human genome, so only viral sequences are left.
  - dekhn 6y ago
    A thousand different technologies were required to make the COVID vaccine. Having the HGP helped, that's for sure. My main complaint is that the HGP leaders basically sold the public and government on a list of accomplishments that never materialized, and yet the underlying data has been invaluable in a wide range of different health problems that they didn't think it would be useful for.
  - wespiser_2018 6y ago
    DNA Printers, or a technique known as "solid phase synthesis" is a different technology that was used by the HGP, but not developed or advanced by them.

      I remember using these 20 years ago to make RNA (they can make RNA as well as DNA, if you add the right reagents, which IIRC were obscenely expensive).

Progress in human genomics is often hidden from view. Eric Green gives some great general pointers, but here are more concrete applications: - NIPT vendors (Natera, Ariosa (Roche), Verinata (Illumina), Sequenom (LabCorp) and others) have successfully commercialized carrier and prenatal screening for severe genetic defects. - CareDx has commercialized pre- and post-screening for organ transplant rejection. - Invitae, Color, Foundation (Roche) and others are scaling genetic testing, specifically clinical exome and panel sequencing (and solving the reimbursement problem in the process, by amortizing the cost of sequencing a patient's DNA across multiple physician-requested tests). Because variants need to be understood by physicians, this also enabled public/private data sharing partnerships for variant characterization (ClinVar). - Grail (Illumina), Natera and others are on the verge of commercializing routine cfDNA cancer screening. And here are more fundamental improvements which may yield more successes like the above: - Oxford Nanopore has provided much needed competition to Illumina in lowering the barrier to portable sequencing and de novo whole genome sequencing. - The ENCODE project has used ever more sophisticated assays to characterize functional regions of the genome. - 10x Genomics has scaled and productized new ways to do single-cell transcriptomics, enabling breakthroughs in understanding functions of genes (by mapping differences in their expression across cell types and conditions) as well as development of CAR-T cell therapies (training and selecting the patient's own immune cells to fight cancer). - UK Biobank has provided privacy-preserving access to a large cohort of annotated genomic data from the NHS, enabling more powerful association studies between genes and disease.

  This is still true, but things are getting better. I'm a few years removed now, but I had the priviledge of getting to admin most major sequencing machines and their data output, and it was a great learning experience for how much the scientific community stands to gain from modern tech stacks imho. One of my favorite examples, I was doing some fastq munging, and had written about a page of perl as per some existing documentation. I kept failing, and eventually just emailed the researcher who wrote the relevant paper... and he said something like "why not use awk, something like $oneliner?" With a few modifications my huge glut of perl became a one line awk... Of course that just means I'm bad at perl, but for some reason it sticks in the mind. I still get invited to bioinformatics conferences... too bad I didn't take them up on it pre-pandemic.

They could work on tackling the epigenetics in human cells along with the differences of the genome between different cells in different organs. It's as big as the original project probably.

I'm a few years removed now, but I had the priviledge of getting to admin most major sequencing machines and their data output, and it was a great learning experience for how much the scientific community stands to gain from modern tech stacks imho. One of my favorite examples, I was doing some fastq munging, and had written about a page of perl as per some existing documentation. I kept failing, and eventually just emailed the researcher who wrote the relevant paper... and he said something like "why not use awk, something like $oneliner?" With a few modifications my huge glut of perl became a one line awk... Of course that just means I'm bad at perl, but for some reason it sticks in the mind. I still get invited to bioinformatics conferences... too bad I didn't take them up on it pre-pandemic.

They could work on tackling the epigenetics in human cells along with the differences of the genome between different cells in different organs. It's as big as the original project probably.

Well, there's also the Human Microbiome Project: https://en.wikipedia.org/wiki/Human_Microbiome_Project https://en.wikipedia.org/wiki/Human_Microbiome_Project Although if you thought the genotype -> phenotype problem was hard, the microbiome -> phenotype problem is likely several orders of magnitude harder.
