In humans, 95% of genes with more than one exon are alternatively spliced.

In mammals, there are four alternatively spliced forms of the Numb protein.

In most cases, each cluster is made up of sequences produced by a single gene, including alternatively spliced transcripts.

Two alternatively spliced variants, encoding the same protein, have been identified.

Two alternatively spliced variants have been characterized to date.

Alternatively spliced variants may be expressed in other tissues.

Two alternatively spliced variants, which encode an identical protein, have been reported.

In humans, 95% of multiexonic genes are alternatively spliced.

Multiple alternatively spliced variants, encoding the same protein, have been found for this gene.

There are at least four different alternatively spliced forms of the protein, two of which are better defined.
