Summary: Identification of indel variants in pooled DNA with spike-in controls
"Error: no local variable "counter" was set." is not a number.
Description
Pooled-DNA sequencing strategies enable fast, accurate, and cost-effect detection of rare variants in large cohorts but current approaches are unable to identify short insertions and deletions (IN/DELs), despite their pivotal role in important disease phenotypes (for example breast and ovarian cancers).
A new algorithm called SPLINTER (Short IN/DEL Prediction by Large deviation Inference and Non-linear True frequency Estimation by Recursion) was developed, which detects and quantifies short IN/DELs as well as single nucleotide substitutions in pooled-DNA samples. SPLINTER can accurately detect rare variants in large pools, providing a novel and sensitive method that will allow for significant progress in the discovery of novel disease-causing rare variants from DNA pools of affected individuals, such as germ-line mutation discovery for breast and ovarian cancer patients.
