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]

Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Jan 13, 2018	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

Variant summary: The SPRED1 c.583-7A>G variant involves the alteration of a non-conserved intronic nucleotide. 5/5 splice prediction tools predict no significant impact on normal splicing. This variant was found in 248/117724 control chromosomes (including 4 homozygotes) from ExAC, predominantly observed in the African subpopulation at a frequency of 0.022615 (229/10126). This frequency is about 9046 times the estimated maximal expected allele frequency of a pathogenic SPRED1 variant (0.0000025), therefore this is likely a benign polymorphism found primarily in the populations of African origin. In addition, multiple clinical diagnostic laboratories/reputable databases have classified this variant as benign/likely benign. Taken together, this variant is classified as Benign. -
