Genes affected

SRSF7 (HGNC:10789): (serine and arginine rich splicing factor 7) 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 N-terminal RNA recognition motif (RRM) for binding RNA and a C-terminal 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. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2018]

Collection Method: clinical testing

The c.455G>T (p.G152V) alteration is located in exon 4 (coding exon 4) of the SRSF7 gene. This alteration results from a G to T substitution at nucleotide position 455, causing the glycine (G) at amino acid position 152 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
