The variant allele was found at a frequency of 0.56 in 151,638 control chromosomes in the GnomAD database, including 25,320 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 0.56 (25320 hom., cov: 31)
• Consequence: C6 ENST00000263413.7 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.214

Genes affected

C6 (HGNC:1339): (complement C6) This gene encodes a component of the complement cascade. The encoded protein is part of the membrane attack complex that can be incorporated into the cell membrane and cause cell lysis. Mutations in this gene are associated with complement component-6 deficiency. Transcript variants encoding the same protein have been described.[provided by RefSeq, Nov 2012]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.662 is higher than 0.05.
