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: The SPRED1 c.424-18G>A variant involves the alteration of a non-conserved intronic nucleotide. One in silico tool predicts a benign outcome for this variant. 5/5 splice prediction tools predict no significant impact on normal splicing and ESE finder predicts no impact on ESE sites at the locus. However, these predictions have yet to be confirmed by functional studies. This variant was found in the large control database ExAC at a frequency of 0.2265353 (27452/121182 control chromosomes [3368 homozygotes]), which is approximately 90614 times the estimated maximal expected allele frequency of a pathogenic SPRED1 variant (0.0000025), providing very strong evidence that this variant is likely a benign polymorphism. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign. To our knowledge, the variant of interest has not been reported in affected individuals via publications, nor has it been evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as benign. -
