Genes affected
SPRED2 (HGNC:17722): (sprouty related EVH1 domain containing 2) SPRED2 is a member of the Sprouty (see SPRY1; MIM 602465)/SPRED family of proteins that regulate growth factor-induced activation of the MAP kinase cascade (see MAPK1; MIM 176948) (Nonami et al., 2004 [PubMed 15465815]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.768G>C (p.K256N) alteration is located in exon 6 (coding exon 6) of the SPRED2 gene. This alteration results from a G to C substitution at nucleotide position 768, causing the lysine (K) at amino acid position 256 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
