Alternative splicing in splicing-related genes

	Genes	AltA	AtlD	AltP	ExonS	IntronR	Overall	Ratio
snRNP proteins	91	6	3	1	3	11	22	23.2%
Splicing factors	109	14	5	0	11	21	38	34.9%
Splicing regulator	60	8	4	2	1	12	20	33.3%
Total	260	28	12	3	15	44	80	30.8%

The column entries are the numbers of genes in which the respective alternative splicing events can occur. AltA, alternative acceptor site; AltD, alternative donor site; AltP, alternative intron position (both acceptor and donor sites are different); ExonS, exon skipping; IntronR, intron retention. The Overall and Ratio columns give the number and fraction of genes with any type of alternative splicing, respectively.
