Altogether, our analyses expand the catalog of driver genes, pathways and mechanisms involved in RT and recognize a similar distribution of these alterations in RT after different therapies, suggesting that treatment-specific pressure is not a major determinant of the driver genomic landscape of these tumors.
We next performed single-cell DNA sequencing (scDNA-seq) of 32 genes in 16 longitudinal samples of 4 patients (12, 19, 365 and 3,299) to validate these evolutionary histories of RT (202,210 cells passing filters, mean of 12,638 cells per sample; Fig. 1a, Supplementary Fig. 2 and Supplementary Table 20). Focusing on patient 19 with a time lapse of 14.4 years from diagnosis to RT (Fig. 3b), the RT subclone (subclone 5) at transformation (T6) carried CDKN2A/B and TP53 (p.G245D) alterations, whereas the main CLL subclones driving the relapse after therapy at T4 and T5 harbored a different TP53 mutation (p.I195T; subclones 3 and 4). The WGS predicted the presence of all these subclones at CLL diagnosis (T1). Using scDNA-seq we identified two small populations accounting for 0.1% of cells carrying the TP53 p.I195T and p.G245D mutations, respectively, at T1, which were also detected at relapse 7.2 years later (T3). The subclone carrying TP53 p.I195T expanded to dominate the second relapse after 3.7 years at T4 and T5 but was substituted by the subclone carrying TP53 p.G245D at T6 in the RT 14.4 years after diagnosis. All these subclones carried the SF3B1 and NOTCH1 mutations of the initial CLL subclone (Fig. 3c and Supplementary Table 20). The scDNA-seq of the three additional cases also corroborated the phylogenies and most of the dynamics inferred from WGS (Extended Data Fig. 6a). These results suggest that CLL evolution to RT is characterized by an early driver diversification probably generated before diagnosis, consistent with the early immunogenetic and DNA methylation diversification previously reported in CLL37,38,39 and that RT may emerge by a selection of pre-existing subclones carrying potent driver mutations rather than a de novo acquisition of leading clones.

In conclusion, our comprehensive characterization of CLL evolution toward RT has revealed new genomic drivers and epigenomic reconfiguration with very early emergence of subclones driving late stages of cancer evolution, which may set the basis for developing single-cell-based predictive strategies. Furthermore, this study also identifies new RT-specific therapeutic targets and suggests that early intervention to eradicate dormant RT subclones may prevent the future development of this lethal complication of CLL.
a. Deletions in chr12 identified in four cases with the minimal deleted region affecting CDKN1B, which expression in CLL and RT sample pairs is shown on the right. The case carrying the deletion at time of RT is labeled in the boxplot. b. Reciprocal translocation juxtaposing CDK6 next to IGKJ5 in patient 4687. c. Deletion in chr1 affecting two cases with the minimal deleted region targeting ARID4B. Its expression in CLL and RT sample pairs is shown in the boxplot on the right. d. Reciprocal translocations truncating CREBBP and CIITA in the RT sample of patient 12. e. Expression levels of known and novel RT-driver genes in CLL and RT paired samples. Cases carrying deletions/mutations at time of RT are labeled. f-j. Complex genomic rearrangements affecting driver genes in five selected RT samples. The circos plots show the SVs (inner links) and CNAs (middle circle) found in each sample. SVs are colored based on whether they are part of a complex event, while CNAs are painted according to their type. Chromosome-specific plots on the right show the main chromosomes affected by complex events targeting driver genes (annotated at the bottom). In these chromosome-specific plots, the color of both CNAs and SVs indicates their type. For patient 12 (f), the expression levels of three genes affected by simple (TRAF3) and complex (SPEN and TNFRS14) chromosomal alterations are shown. For patient 4675 (j), the partner of the translocations found in chr3 and chr8 are not specified for simplicity due to the high number of clustered structural events. All boxplots: center line, median; box limits, upper/lower quartiles; whiskers, 1.5interquartile range; points, individual samples. All p values are from two-sided T tests.
a. Subclonal reconstruction and clonal evolution of three cases (3299, 12 and 365) with WGS and scDNA-seq data available. The upper fish plot shows the clonal evolution along the course of the disease inferred from WGS analyses. Each color represents a different subclone and their height is proportional to their cancer cell fraction (CCF) in each time point (vertical lines). The treatments that the patient received and the elapsed time (in years) between samples are indicated at the top. The tissue is indicated for samples of patient 3299 in which different tissues were analyzed by WGS and scDNA-seq in the same time point. The phylogeny of the subclones is depicted together with the main driver alterations (top right). The lower bar plots show the dynamics of the different subclones according to the scDNA-seq analyses. The total number of cells per sample is shown at the bottom. The number of cells assigned to each subclone can be found in Supplementary Table 20. The mutation tree inferred from scDNA-seq data is shown at the bottom-right part. b-c. Subclonal architecture and dynamics of six cases with longitudinal samples (b) and two cases with spatial samples (c) analyzed by WGS.
The 964 was considered to be 85% new as compared to its predecessor, the Carrera 3.2. The first 964s available in 1989 were all wheel drive equipped "Carrera 4" models; Porsche added the rear wheel drive Carrera 2 variant to the range in 1990. Both variants were available as a coupé, Targa or Cabriolet. The 964 Carrera was the last generation sold with the traditional removable Targa roof until the 2011 991 (993, 996, and 997 versions used instead a complex glass-roof "greenhouse" system). A new naturally aspirated engine called the M64 was used for 964 models, with a flat-6 displacement of 3.6 litres.Porsche substantially revised the suspension, replacing torsion bars with coil springs and shock absorbers.[4] Power steering and ABS brakes were added to the 911 for the first time; both were standard. The exterior bumpers and fog lamps became flush with the car for better aerodynamics. A new electric rear spoiler raised at speeds above 50 mph (80 km/h) and lowered down flush with the rear engine lid at lower speeds. A revised interior featured standard dual airbags beginning in late 1989 for all North American production 1990 MY cars. A new automatic climate control system provided improved heating and cooling. Revised instrumentation housed a large set of warning lights that were tied into the car's central warning system, alerting the driver to a possible problem or malfunction.
There were two distinct incarnations of the air-cooled 911 Speedster. The first was the 1989 model year Speedster. Shown at the 1988 Frankfurt Motor Show beside the upcoming Carrera 4, the 1989 Speedster actually shared more in common with the 930 turbo than with the upcoming 964 generation 911s, causing it to be looked upon, in retrospect, as a much inferior "driver's car" to the later 1994 Speedster. More than three quarters (641) of the 800 built had the "Turbo look" wide-body option.[12]
Returns a flag with the connection state.Depends on the nature of API used by each driver.The state does not reflect only on the connection status (when SSH), it must also take intoconsideration other parameters, e.g.: NETCONF session might not be usable, althought theunderlying SSH session is still open etc.

The driver's license of any person convicted under this section shall be revoked pursuant to subsection B of 46.2-391.
Commonly-used keys, such as the arrow keys or pressing Alt to reach menus, can be mapped directly to Braille inputs.The driver for each Braille display comes pre-equipped with some of these assignments.You can change these assignments or add new emulated keys from the Input Gestures dialog.
Note that this option is only useful if your braille display has a Perkins-style keyboard and this feature is supported by the braille display driver.If input is not supported on a display which does have a braille keyboard, this will be noted in the Supported Braille Displays section.
The Select Braille Display dialog, which can be opened by activating the Change... button in the Braille category of the NVDA settings dialog, allows you to select which Braille display NVDA should use for braille output.Once you have selected your braille display of choice, you can press Ok and NVDA will load the selected display.If there is an error loading the display driver, NVDA will notify you with a message, and continue using the previous display, if any.
Please note: If you connect multiple Braille Displays to your machine at the same time which use the same driver (E.g. connecting two Seika displays),it is currently impossible to tell NVDA which display to use.Therefore it is recommended to only connect one Braille Display of a given type / manufacturer to your machine at a time.
The checkboxes in this list allow you to enable specific categories of debug messages in NVDA's log.Logging these messages can result in decreased performance and large log files.Only turn one of these on if specifically instructed to by an NVDA developer e.g. when debugging why a braille display driver is not functioning correctly.
The eSpeak NG synthesizer is built directly into NVDA and does not require any other special drivers or components to be installed.On Windows 7, 8 and 8.1, NVDA uses eSpeak NG by default (Windows OneCore is used in Windows 10 and later by default).As this synthesizer is built into NVDA, this is a great choice for when running NVDA off a USB thumb drive on other systems. 2ff7e9595c
