Genes affected
SRSF6 (HGNC:10788): (serine and arginine rich splicing factor 6) The protein encoded by this gene is involved in mRNA splicing and may play a role in the determination of alternative splicing. The encoded nuclear protein belongs to the splicing factor SR family and has been shown to bind with and modulate another member of the family, SFRS12. Alternative splicing results in multiple transcript variants. In addition, two pseudogenes, one on chromosome 17 and the other on the X chromosome, have been found for this gene.[provided by RefSeq, Sep 2010]

The c.697C>G (p.R233G) alteration is located in exon 6 (coding exon 6) of the SRSF6 gene. This alteration results from a C to G substitution at nucleotide position 697, causing the arginine (R) at amino acid position 233 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
