Genes affected

SRSF1 (HGNC:10780): (serine and arginine rich splicing factor 1) This gene encodes a member of the arginine/serine-rich splicing factor protein family. The encoded protein can either activate or repress splicing, depending on its phosphorylation state and its interaction partners. Multiple transcript variants have been found for this gene. There is a pseudogene of this gene on chromosome 13. [provided by RefSeq, Jun 2014]

SRSF1 Gene-Disease associations (from GenCC):

• neurodevelopmental disorder with dysmorphic facies and behavioral abnormalities
