Publication number: 20190376137Abstract: The identification of mutations that are present in a small fraction of DNA templates is essential for progress in several areas of biomedical research. Though massively parallel sequencing instruments are in principle well-suited to this task, the error rates in such instruments are generally too high to allow confident identification of rare variants. We here describe an approach that can substantially increase the sensitivity of massively parallel sequencing instruments for this purpose. One example of this approach, called “Safe-SeqS” for (Safe-Sequencing System) includes (i) assignment of a unique identifier (UID) to each template molecule; (ii) amplification of each uniquely tagged template molecule to create UID-families; and (iii) redundant sequencing of the amplification products. PCR fragments with the same UID are truly mutant (“super-mutants”) if ?95% of them contain the identical mutation.Type: ApplicationFiled: May 21, 2019Publication date: December 12, 2019Inventors: Bert Vogelstein, Kenneth W. Kinzler, Nickolas Papadopoulos, Isaac A. Kinde

PCR fragments with the same UID are truly mutant (“super-mutants”) if ?95% of them contain the identical mutation. We illustrate the utility of this approach for determining the fidelity of a polymerase, the accuracy of oligonucleotides synthesized in vitro, and the prevalence of mutations in the nuclear and mitochondrial genomes of normal cells.Type: GrantFiled: July 30, 2015Date of Patent: November 8, 2016Assignee: The Johns Hopkins UniversityInventors: Bert Vogelstein, Kenneth W.

Publication number: 20160208340Abstract: TERT promoter mutations occur in both papillary and flat lesion bladder cancers, are the most frequent genetic alterations identified to date in noninvasive precursor lesions of the bladder, are detectable in urine, and appear to be strongly associated with bladder cancer recurrence. The TERT promoter mutations are useful urinary biomarker for both the early detection and monitoring of bladder neoplasia.Type: ApplicationFiled: March 22, 2016Publication date: July 21, 2016Applicant: The Johns Hopkins UniversityInventors: Bert Vogelstein, Kenneth W.

Publication number: 20150376691Abstract: Massively parallel sequencing of cell-free, maternal plasma DNA was recently demonstrated to be a safe and effective screening method for fetal chromosomal aneuploidies. Here, we report an improved sequencing method achieving significantly increased throughput and decreased cost by replacing laborious sequencing library preparation steps with PCR employing a single primer pair. Using this approach, samples containing as little as 4% trisomy 21 DNA could be readily distinguished from euploid samples.Type: ApplicationFiled: July 7, 2015Publication date: December 31, 2015Inventors: Bert VOGELSTEIN, Kenneth W.

Publication number: 20150292027Abstract: The recently developed liquid-based Papanicolaou (Pap) smear allows not only cytologic evaluation but also collection of DNA for detection of HPV, the causative agent of cervical cancer. We tested these samples to detect somatic mutations present in rare tumor cells that might accumulate in the cervix once shed from endometrial and ovarian cancers. A panel of commonly mutated genes in endometrial and ovarian cancers was assembled and used to identify mutations in all 46 endometrial or cervical cancer tissue samples. We were able also able to identify the same mutations in the DNA from liquid Pap smears in 100% of endometrial cancers (24 of 24) and in 41% of ovarian cancers (9 of 22). We developed a sequence-based method to query mutations in 12 genes in a single liquid Pap smear without prior knowledge of the tumor's genotype.Type: ApplicationFiled: October 17, 2013Publication date: October 15, 2015Applicant: THE JOHNS HOPKINS UNIVERSITYInventors: Isaac Kinde, Kenneth W.
