    This is from Vadim Urasin co founder of YFull:

    "We have registered ID YF10000 yesterday. A milestone. Thank you all for orders. By the way, in this batch we have added about a hundred samples from scientific papers of this year (later I will write references to papers). They have a lot of new SNPs. This is a main reason of delay with results."

    This is a remarkable accomplishment in my mind which represents 10,000 samples in the Ytree database. This is a remarkable effort that represents citizen scientists, scientific studies and universities contributing this information in a public forum for everyone to see.

    This I think brings to conclusion this thread and yes we can sequence the Y for all to see. Its been a great ride and it will continue with new data from current and ancient populations. A well done by everyone involved and thanks to SEQanswers that gave me a podium to discuss these issues.

    This is a very nice announcement and shows how far we have come in products available to the public.

    PUBLIC RELEASE: 28-JAN-2016
    Full GenomesTM Corporation collaborates with Novogene to offer low-cost whole genome ancestry test
    Comprehensive GenomeGuide now available at $895

    It will be in the range of 15x - 20x, since our results that is the range that gives good Y chromosome coverage. 20x is equivalent to Y Elite, in terms of the Callable Loci metric. So, its not fixed at specific number but we'll target it in that range as we get more data.

    From other beta data:

    Callable loci
    20x: 13,888,138

    Mapped Y coverage
    20x: 22,818,005

    The various Y Elite tests all average approx 14 million Callable Loci, however, the purpose here isn't to replace the Y Elite product, although ultimately, it is possible that a whole genome test will be no more expensive.

    Whole Genome Sequencing and Y Chromosome Sequencing

    There has been an interesting discussion at Rootsweb about Whole Genome Sequencing and Y sequencing. The entire thread can be read there.



    I have distilled some of the conversation into three points of information coming from Justin Loe Fullgenomes, Thomas Krahn and Tim Janzen. All three of these folks have been leaders in the area of testing over the years. We are coming eventually to a price point where Whole Genome Sequencing will probably replace sequencing the Y. The conversations below will make this more clear.

    FullGenomes
    Whole Genome Sequencing 2x $280
    Whole Genome Sequencing 4x $395
    Whole Genome Sequencing 10x $725
    Whole Genome Sequencing 15x $895
    Whole Genome Sequencing 20x $1,200
    Whole Genome Sequencing 30x $1,650
    Ultimate 100x Whole Genome $5,350
    Y Elite 2.0 Sequencing $775


    The largest cost factor for Y chromosome tests is not the sequencing, but the enrichment procedure. With enrichment the price will never drop far below $400, so you might as well sequence with sufficient coverage.

    On the long run there is no future for BigY and FGCs Y tests since the WGS tests keep dropping in the price, but Y tests don't.

    Thomas Krahn

    Justin Loe from FullGenomes just posted the information below on another list:


    Mapped Y coverage
    30x 22,856,938
    10x 22,025,697
    4x 17,678,170
    2x 13,755,442

    Average Callable Loci
    30x 14,558,001
    10x 8,046,540
    4x 1,050,996
    2x 349,397

    Y Elite 2.0:
    14,000,000 Callable Loci approximately on average"

    It thus appears that one needs to order at least the 30x whole genome sequence from FullGenomes to get the same number of callable Y chromosome loci as you can get from the Y Elite 2.0 test.

    I would like to point out that even Full Genomes' Ultimate 100x Whole Genome is not the Holy Grail in whole genome sequencing because the data is unphased. What we are still waiting for is a company to generate phased whole genome sequencing data with an extremely high level of accuracy. I know that companies are working on this, but so far it has been challenging for the companies to do.

    Sincerely,
    Tim Janzen

    YTree 1200 Sardinian samples from Paolo Francalacci's article

    This is some very exciting news that I was lucky enough to be involved in a small way. Many new samples from Paolo Francalacci's paper are being added to the YFull tree. More information and comments can be seen at the Yfull Facebook page. I would like to thank Paolo and Vadim for their efforts in this endeavor. I hope this is the beginning of academic data being brought into a public forum for all to see. Current Technical requirements: .FASTQ or .BAM file; coverage min 25X; read length min 100 bp for determining age estimations. Currently the YTree at YFull is at revision 3.17.

    "We started to add in our YTree 1200 Sardinian samples from Paolo Francalacci's article http://www.ncbi.nlm.nih.gov/pubmed/23908240 Kerry O'Dair thank you for help with first communication with Paolo. At first we will add 49 samples. They have ids 4399-4401, 4411, 4416, 4592-4632 (numbers of 3 samples indefined yet). Later we create special page with list of samples anf their subclades and we will change way to show them in our YTree and add reference to Paolo's article.
    Unfortunately we can not add these samples in any group for reason of keeping privacy. Also we will not use these sample for age estimation because of their low quality. But you will see changes in our YTree. I think we will define many new subclades. Each batch we plan to add about 60 Sardinian samples.
    We don't promise to add all of 1200 samples but we will add many of them."

    Looking forward to seeing this paper when available. This is right in my wheel house dealing with the E haplogroup and the E-M35 subclade. This is what the sequencing of the Y is all about. Mr Cruciani is an author of this paper and has always been a leader in this kind of anaylsis. Really looking forward to reading this paper.

    Detection of phylogenetically informative polymorphisms in the entire euchromatic portion of human Y chromosome from a Sardinian sample

    Background Next-Generation Sequencing methods have led to a great increase in phylogenetically useful markers within the male specific portion of the Y chromosome, but previous studies have limited themselves to the study of the X-degenerate regions. Methods DNA was extracted from peripheral blood samples of adult males whose paternal grandfathers were born in Sardinia. The DNA samples were sequenced, genotyped and subsequently analysed for variant calling for approximately 23.1 Mbp of the Y chromosome. A phylogenetic tree was built using Network 4.6 software. Results From low coverage whole genome sequencing of 1,194 Sardinian males, we extracted 20,155 phylogenetically informative single nucleotide polymorphisms from the whole euchromatic region, including the X-degenerate, X-transposed, and Ampliconic regions, along with variants in other unclassified chromosome intervals and in the readable sequences of the heterochromatic region. Conclusions The non X-degenerate classes contain a significant portion of the phylogenetic variation of the whole chromosome and their inclusion in the analysis, almost doubling the number of informative polymorphisms, refining the known molecular phylogeny of the human Y chromosome.

    Here is an exchange with Yfull people on samples in their database on Facebook.

    What is the total number of samples in the database today? This number would include all sources of sequenced data FullGenomes, FTDNA, 1000 Genomes Etc. Are there other sources besides the three I have named?

    Vadim Urasin about 3300 samples. Almost all samples are from those 3 sources. Several samples are from scientific articles also. Version 3.9 of experimental tree to be released soon.

    Also some stats from FullGenomes Folks

    Here's our latest progress. Done by a team of 3 people.

    Our latest numbers:

    1. Total SNP discovery: 35,000 SNPs
    2. Total FGC SNPs listed or in investigation status in ISOGG: 630
    3. Total R1b SNPs from FGC in ISOGG: 133
    4. Total FGC SNPs in YSEQ: 2,803 (as of April 14)
    5. Total kits sequenced or analyzed: approximately 1,000 (10 mb (Big Y) or 14 mb (FGC/BGI)

    The progress in the last 12 months has been amazing. A great deal of this effort is coming from the citizen scientists who are not waiting for the big companies to take some action to interpret the data.

    Defining a New Rate Constant for Y-Chromosome SNPs based on Full Sequencing Data

    Two important advances: 1) the accumulation of BigY and FGC test data, and 2) the publication of Y-chromosome sequences for three ancient samples (Anzick-1, Ust-Ishim, and K14), have made it possible to estimate the average rate of basesubstitutions (SNPs). The authors of this study have developed a new method of selecting true mutations in modern and ancient samples, and have defined with high accuracy the rate constant of SNP mutations: 0.82 · 10-9 per year per bp (95% CI: (0.70 - 0.94) · 10-9).

    This is information released by Yfull with version 3.4 of their Ytree which has age estimations for subclades and TMRCA. These will be refined over time with new samples. My particular results certainly are in line with previous estimations of time made independently by myself and others. This really is a significant step forward in dating the Y Chromosome with so many samples. Many thanks to the people at YFull. Below their statement on snp dating.


    Vadim Urasin YFull.com: Y-Chr Sequence Interpretation Service


    In the version 3.4 of Y-Tree we plan to show an estimation of age for all subclades with at least one Big Y or Y Elite. The algorythm of estimation by SNP count we will explain later in an article written by Adamov, Vladimir Gurianov, Sergey Karzhavin, Vadim Urasin We have checked our estimation by information of common ancestors our clients. For 12 of 14 subclades estimated age is inside 95% confidence interval. But estimated age of I-YP1012 and I-A379 is not. In the chart you can see all 14 subclades with known ancestors. For all subclades in the Y-Tree a confidence interval depends from number of samples. For subclades with 1 sample a bounds of 95% confidence interval of age estimation are -48.8% +61.6% in the average, for subclades with 2 samples a bounds of 95% confidence interval are -43.3% +50.1% in the average, for 3 samples: -34.6% +37,3%, for 4 samples: -28,9% +32,2%. More samples - better estimation

    New open source paper with supplemental files on:

    The Y-Chromosome Tree Bursts into Leaf: 13,000 High-Confidence SNPs Covering the Majority of Known Clades

    Abstract

    Many studies of human populations have used the male-specific region of the Y chromosome (MSY) as a marker, but MSY sequence variants have traditionally been subject to ascertainment bias. Also, dating of haplogroups has relied on Y-specific short tandem repeats (STRs), involving problems of mutation rate choice, and possible long-term mutation saturation. Next-generation sequencing can ascertain single nucleotide polymorphisms (SNPs) in an unbiased way, leading to phylogenies in which branch-lengths are proportional to time, and allowing the times-to-most-recent-common-ancestor (TMRCAs) of nodes to be estimated directly. Here we describe the sequencing of 3.7 Mb of MSY in each of 448 human males at a mean coverage of 51×, yielding 13,261 high-confidence SNPs, 65.9% of which are previously unreported. The resulting phylogeny covers the majority of the known clades, provides date estimates of nodes, and constitutes a robust evolutionary framework for analyzing the history of other classes of mutation. Different clades within the tree show subtle but significant differences in branch lengths to the root. We also apply a set of 23 Y-STRs to the same samples, allowing SNP- and STR-based diversity and TMRCA estimates to be systematically compared. Ongoing purifying selection is suggested by our analysis of the phylogenetic distribution of nonsynonymous variants in 15 MSY single-copy genes.

    Abstract
    Currently, several different Y-chromosomal phylogenies and haplogroup nomenclatures are presented in scientific literature and at conferences demonstrating the present diversity in Y-chromosomal phylogenetic trees and Y-SNP sets used within forensic and anthropological research. This situation can be ascribed to the exponential growth of the number of Y-SNPs discovered due to mostly next-generation sequencing (NGS) studies. As Y-SNPs and their respective phylogenetic positions are important in forensics, such as for male lineage characterization and paternal bio-geographic ancestry inference, there is a need for forensic geneticists to know how to deal with these newly identified Y-SNPs and phylogenies, especially since these phylogenies are often created with other aims than to carry out forensic genetic research. Therefore, we give here an overview of four categories of currently used Y-chromosomal phylogenies and the associated Y-SNP sets in scientific research in the current NGS era. We compare these categories based on the construction method, their advantages and disadvantages, the disciplines wherein the phylogenetic tree can be used, and their specific relevance for forensic geneticists. Based on this overview, it is clear that an up-to-date reduced tree with a consensus Y-SNP set and a stable nomenclature will be the most appropriate reference resource for forensic research. Initiatives to reach such an international consensus are therefore highly recommended.

    Choosing Between NGS and qPCR
    by seqadmin



    Next-generation sequencing (NGS) and quantitative polymerase chain reaction (qPCR) are essential techniques for investigating the genome, transcriptome, and epigenome. In many cases, choosing the appropriate technique is straightforward, but in others, it can be more challenging to determine the most effective option. A simple distinction is that smaller, more focused projects are typically better suited for qPCR, while larger, more complex datasets benefit from NGS. However,...
