The variant allele was found at a frequency of 0.124 in 152,168 control chromosomes in the GnomAD database, including 1,361 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 0.12 (1361 hom., cov: 32)
• Consequence: TEP1 NM_007110.5 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -1.91

Genes affected

TEP1 (HGNC:11726): (telomerase associated protein 1) This gene product is a component of the ribonucleoprotein complex responsible for telomerase activity which catalyzes the addition of new telomeres on the chromosome ends. The telomerase-associated proteins are conserved from ciliates to humans. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.97).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.172 is higher than 0.05.
