BASIC TEXT SEARCH Select your search field from the pull-down menu, enter your search term in the adjacent window and click the "Submit Query" button. The "Mutation Names" search will look for a match in cDNA, protein, or legacy name. You can also search all fields by selecting "All Fields". For advanced search click on the "Advanced Search" button below.


  • Search is case insensitive.
  • Search term can consist of a whole word or part of a word e.g.
    • Searching for "551" in the Protein Name field will retrieve all mutations that alter the protein at position 551.
    • Searching for "del" in Mutation Names will retrieve all deletion mutations (but it may take awhile).

c.33281_3367+268del355insTGTTAA 3413del355_insTGTTAA exon 20 Partial deletion of exon 17b. It removes 355 bp, i.e. from nt 3413 (in codon 1094) to 3499+ 268 in intron 17b; the sequence "TGTTAA" is inserted at the breakpoints. A stop codon appears very early in the new sequence but the consequences at the RNA level remain to be studied.
