WebProteomic genotyping is the use of genetically variant peptides (GVPs) that contain single-amino-acid polymorphisms to infer the genotype of matching nonsynonymous single-nucleotide polymorphisms for the individual from whom the protein sample originated. This can be used to statistically associate an individual to evidence found at a crime scene. WebSep 1, 2024 · The resulting proteomic and matching exome datasets were used to discover, characterize and validate 60 genetically variant peptides. An average of 28.8 ± 4.4 genetically variant peptides were detected from each subject resulting in a total of 264 SNP allele inferences with 260 true and 4 false positives, a false discovery rate of 1.5%.

WebGenetically variant peptides (GVPs) are the products of single nucleotide polymorphisms (SNPs) in the genes that code for proteins. (A single nucleotide polymorphism is a DNA sequence variation occurring when a single nucleotide in the genome or other shared sequence differs between members of a species or paired chromosomes in an individual.)
