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]

Variant summary: SPRED1 c.1202G>T (p.Cys401Phe) results in a non-conservative amino acid change located in the Sprouty domain (IPR007875) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 2.8e-05 in 251246 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1202G>T has been reported in the literature as a VUS in the settings of multigene panel testing in one individual within a cohort of Finnish individuals affected with dilated cardiomyopathy (DCM) (example, Akinrinade_2015). The report does not provide unequivocal conclusions about association of the variant with Neurofibromatosis Type 1-Like Syndrome (Legius Syndrome). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

This missense change has been observed in individual(s) with dilated cardiomyopathy (PMID: 26084686). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (Invitae) indicates that this missense variant is not expected to disrupt SPRED1 function. ClinVar contains an entry for this variant (Variation ID: 468791). This variant is present in population databases (rs779058019, gnomAD 0.006%). This sequence change replaces cysteine, which is neutral and slightly polar, with phenylalanine, which is neutral and non-polar, at codon 401 of the SPRED1 protein (p.Cys401Phe). -
