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]

The c.424-5A>G variant in SPRED1 has not been previously reported in individuals with clinical features of RASopathy, but has been identified in 3/24030 African chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinst itute.org; dbSNP rs752656697). This variant is located in the 3' splice region. Computational tools do not suggest an impact to splicing. However, this informat ion is not predictive enough to rule out pathogenicity. In summary, the clinical significance of the c.424-5A>G variant is uncertain. ACMG/AMP Criteria applied: BP7. -
