The variant was absent in control chromosomes in GnomAD project. 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: not found (cov: 32)
• Consequence: TERF2IP NM_018975.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 1.68

Genes affected

TERF2IP (HGNC:19246): (TERF2 interacting protein) Enables G-rich strand telomeric DNA binding activity and phosphatase binding activity. Involved in several processes, including positive regulation of NIK/NF-kappaB signaling; regulation of nucleobase-containing compound metabolic process; and regulation of protein modification process. Located in chromosome, telomeric region; cytosol; and nuclear body. Part of shelterin complex. [provided by Alliance of Genome Resources, Apr 2022]

KARS1 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.
