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]

377-10A>G in intron 3 of SPRED1: This variant has been identified by our labora tory in a proband and an unaffected parent. This variant is located in the 3' sp lice acceptor region but does not affect the invariant -1 and -2 positions. In a ddition, computational tools do not predict altered splicing. This variant has b een identified in 0.05% (2/4392) of African American chromosomes from a large po pulation by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS /). In addition, the adenine nucleotide is not conserved across evolutionary dis tinct species at position 377-10, and several mammals have a guanine at this pos ition. Therefore, the 377-10A>G variant is likely to be benign. -
