Title: Genetic mapping of 262 loci derived from expressed sequences in a murine interspecific cross using single-strand conformational polymorphism analysis. Author: Brady KP, Rowe LB, Her H, Stevens TJ, Eppig J, Sussman DJ, Sikela J, Beier DR. Journal: Genome Res; 1997 Nov; 7(11):1085-93. PubMed ID: 9371744. Abstract: We have demonstrated previously that noncoding sequences of genes are a robust source of polymorphisms between mouse species when tested using single-strand conformation polymorphism (SSCP) analysis, and that these polymorphisms are useful for genetic mapping. In this report we demonstrate that presumptive 3'-untranslated region sequence obtained from expressed sequence tags (ESTs) can be analyzed in a similar fashion, and we have used this approach to map 262 loci using an interspecific backcross. These results demonstrate SSCP analysis of genes or ESTs is a simple and efficient means for the genetic localization of transcribed sequences, and is furthermore an approach that is applicable to any system for which there is sufficient sequence polymorphism.[Abstract] [Full Text] [Related] [New Search]
