The variant allele was found at a frequency of 0.00241 in 152,080 control chromosomes in the GnomAD database, including 2 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 0.0024 (2 hom., cov: 32)
• Consequence: CENPC NM_001812.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.620

Genes affected

CENPC (HGNC:1854): (centromere protein C) Centromere protein C 1 is a centromere autoantigen and a component of the inner kinetochore plate. The protein is required for maintaining proper kinetochore size and a timely transition to anaphase. A putative pseudogene exists on chromosome 12. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BS2: High Homozygotes in GnomAd4 at 2 AR gene
