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]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 17-58006491-A-C is Pathogenic according to our data. Variant chr17-58006491-A-C is described in ClinVar as [Pathogenic]. Clinvar id is 2429777.Status of the report is criteria_provided_single_submitter, 1 stars.
