Relevance to Autism
Fliedner et al., 2020 described eleven individuals with heterozygous SCAF4 variants that presented with a neurodevelopmental disorder characterized by developmental delay and intellectual disability, seizures, behavioral abnormalities, and various skeletal and structural anomalies; five individuals in this cohort were reported to have autism, while an additional two individuals presented with autistic features.
Molecular Function
This gene likely encodes a member of the arginine/serine-rich splicing factor family. A similar protein in Rat appears to bind the large subunit of RNA polymerase II and provide a link between transcription and pre-mRNA splicing.
