Table 4

In silico analysis of all induced or spontaneous alleles (4,984) with phenotypes reported in the Mouse Genomes Database [1]

Mutation

Number of alleles

Unknown or uncharacterized

3,105

Introns, UTRs, regulatory regions (including instances where the lesion is not known but coding sequence has been sequenced), cryptic splice sites, inversions

150

Exons (single nucleotide substitutions, deletions, insertions)

1,581

Conserved splice acceptor or donor

148

This analysis shows that the vast majority of induced or spontaneous alleles that have been characterized at the molecular level (1,879) are mutations in coding sequence or conserved splice acceptor/splice donor sites.
