WebMar 27, 2024 · Recently, we reported a C→T single-nucleotide polymorphism (SNP) in the vascular endothelial growth factor receptor 1 (VEGFR-1/Flt1) promoter that merges human VEGF and p53 pathways. This finding suggested a new layer in environmental controls of a pathway relevant to several diseases. WebMar 20, 2024 · single nucleotide polymorphism (SNP), variation in a genetic sequence that affects only one of the basic building blocks—adenine (A), guanine (G), thymine (T), or cytosine (C)—in a segment of a DNA molecule and that occurs in more than 1 percent of a population. An example of an SNP is the substitution of a C for a G in the nucleotide …
