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]
SPRED2 Gene-Disease associations (from GenCC):
  • Noonan syndrome 14

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 1.3079 (below the threshold of 3.09). Trascript score misZ: 0.70292 (below the threshold of 3.09). GenCC associations: The gene is linked to Noonan syndrome 14.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.892
