Genes affected

SPRED1 (HGNC:20249): (sprouty related EVH1 domain containing 1) The protein encoded by this gene is a member of the Sprouty family of proteins and is phosphorylated by tyrosine kinase in response to several growth factors. The encoded protein can act as a homodimer or as a heterodimer with SPRED2 to regulate activation of the MAP kinase cascade. Defects in this gene are a cause of neurofibromatosis type 1-like syndrome (NFLS). [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 104 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 15-38253190-GCGAGGAGACGGCGA-G is Pathogenic according to our data. Variant chr15-38253190-GCGAGGAGACGGCGA-G is described in ClinVar as [Pathogenic]. Clinvar id is 547789.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr15-38253190-GCGAGGAGACGGCGA-G is described in Lovd as [Pathogenic].
