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]

SRSF1 Gene-Disease associations (from GenCC):

• neurodevelopmental disorder with dysmorphic facies and behavioral abnormalities

ACMG classification

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 4 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 3.9581 (above the threshold of 3.09). Trascript score misZ: 5.8555 (above the threshold of 3.09). GenCC associations: The gene is linked to neurodevelopmental disorder with dysmorphic facies and behavioral abnormalities.
• PP5: Variant 17-58005875-C-T is Pathogenic according to our data. Variant chr17-58005875-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 2429781.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
