The variant allele was found at a frequency of 0.342 in 152,034 control chromosomes in the GnomAD database, including 9,186 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 0.34 (9186 hom., cov: 32)
• Consequence: SPIRE1 NM_001128626.2 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.194

Genes affected

SPIRE1 (HGNC:30622): (spire type actin nucleation factor 1) Spire proteins, such as SPIRE1, are highly conserved between species. They belong to the family of Wiskott-Aldrich homology region-2 (WH2) proteins, which are involved in actin organization (Kerkhoff et al., 2001 [PubMed 11747823]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.516 is higher than 0.05.
