Genes affected

SRSF5 (HGNC:10787): (serine and arginine rich splicing factor 5) The protein encoded by this gene is a member of the serine/arginine (SR)-rich family of pre-mRNA splicing factors, which constitute part of the spliceosome. Each of these factors contains an RNA recognition motif (RRM) for binding RNA and an RS domain for binding other proteins. The RS domain is rich in serine and arginine residues and facilitates interaction between different SR splicing factors. In addition to being critical for mRNA splicing, the SR proteins have also been shown to be involved in mRNA export from the nucleus and in translation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.664C>T (p.R222W) alteration is located in exon 8 (coding exon 7) of the SRSF5 gene. This alteration results from a C to T substitution at nucleotide position 664, causing the arginine (R) at amino acid position 222 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
