The variant allele was found at a frequency of 0.451 in 152,030 control chromosomes in the GnomAD database, including 18,144 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 0.45 (18144 hom., cov: 33)
• Consequence: NCAPD3 NM_015261.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.932

Genes affected

NCAPD3 (HGNC:28952): (non-SMC condensin II complex subunit D3) Condensin complexes I and II play essential roles in mitotic chromosome assembly and segregation. Both condensins contain 2 invariant structural maintenance of chromosome (SMC) subunits, SMC2 (MIM 605576) and SMC4 (MIM 605575), but they contain different sets of non-SMC subunits. NCAPD3 is 1 of 3 non-SMC subunits that define condensin II (Ono et al., 2003 [PubMed 14532007]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.95).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.745 is higher than 0.05.
