The variant allele was found at a frequency of 0.547 in 152,076 control chromosomes in the GnomAD database, including 23,004 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.55 (23004 hom., cov: 33)
• Consequence: SPRED2 NM_181784.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.759

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.759 is higher than 0.05.
