The variant allele was found at a frequency of 0.243 in 152,068 control chromosomes in the GnomAD database, including 4,880 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 0.24 (4880 hom., cov: 31)
• Consequence: SPC25 ENST00000451987.5 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.299

Genes affected

SPC25 (HGNC:24031): (SPC25 component of NDC80 kinetochore complex) This gene encodes a protein that may be involved in kinetochore-microtubule interaction and spindle checkpoint activity. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.304 is higher than 0.05.
