Genes affected

SLFN14 (HGNC:32689): (schlafen family member 14) The protein encoded by this gene plays an important role in platelet formation and function. Defects in this gene are a cause of thrombocytopenia with excessive bleeding. [provided by RefSeq, Jul 2016]

SLFN14 Gene-Disease associations (from GenCC):

• platelet-type bleeding disorder 20

  Inheritance: AD Classification: STRONG, MODERATE, SUPPORTIVE Submitted by: Ambry Genetics, ClinGen, Labcorp Genetics (formerly Invitae), Orphanet

ACMG classification

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 17-35557411-T-C is Pathogenic according to our data. Variant chr17-35557411-T-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 225535.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP4: Computational evidence support a benign effect (MetaRNN=0.23653913). . Strength limited to SUPPORTING due to the PP5.
