Patent number: 8731956Abstract: Techniques for allowing doctors and clinicians to upload genetic data associated with patients for comparison with previously-uploaded genetic data associated with other patients are described herein. These techniques may also allow doctors and clinicians to create notations associated with uploaded patient data. Both the previously-uploaded data as well as the created notations may be used by doctors and clinicians in attempting to diagnosis patients. That is, these techniques allow previously-acquired knowledge to be widely shared for the future benefit in attempting to detect genetic syndromes.Type: GrantFiled: November 5, 2008Date of Patent: May 20, 2014Assignee: Signature Genomic LaboratoriesInventors: Bassem A. Bejjani, Lisa G. Shaffer, Blake Ballif, Brice Tebbs, Kyle Sundin

Publication number: 20110086772Abstract: Multiplex (+/?) stranded analyses, such as array comparative genomic hybridization (aCGH), are provided for detecting chromosomal rearrangements associated with cancer and other diseases. For example, an illustrative multiplex array for CGH includes discrete plus (+) strand and minus (?) strand DNA probes, complementary to each other but separable on the CGH array. The minus (?) strand DNA probes recover diagnostic information lost to conventional microarrays, since many genes transcribe from the minus (?) strand. In an illustrative system, patient and control DNA samples are prepared for CGH by amplification and labeling using comprehensive primers that generate both plus (+) strands and minus (?) strands of DNA in the samples. The breakpoints of a translocated chromosome may be detected on a multiplex microarray by DNA probes of one polarity, while DNA copy number changes associated with the translocation region may be detected by corresponding DNA probes of the complementary polarity.Type: ApplicationFiled: September 27, 2010Publication date: April 14, 2011Applicant: Signature Genomics Laboratories LLCInventors: Lisa McDaniel, Blake Ballif, Roger Schultz, Brice Tebbs, Bassem Bejjani, Lisa Shaffer

Patent number: 7910353Abstract: Methods and apparatuses for selecting and arranging clinically relevant chromosomal loci allow an exemplary diagnostic array to simultaneously test for numerous genetic alterations that occur in many different parts of the human genome. Clinically irrelevant or ineffective loci are eliminated. One implementation increases reliability and accuracy by dividing the base-pair sequence of each chromosomal locus into segments and then assigning nucleic acid clones for comparative genomic hybridization to each different segment. The segments may overlap for increased resolution and control. Clones representing segments that are adjacent on a native chromosome are placed in non-adjacent target areas of the array to avoid interfering hybridization reactions. Arrangement motifs within an array may be redundantly repeated for high availability and increased reliability and accuracy of results. Techniques, hardware, software, logic engines, loci collections, and diagnostic arrays are described.Type: GrantFiled: February 11, 2005Date of Patent: March 22, 2011Assignee: Signature Genomic LaboratoriesInventors: Lisa G.
