TERB1

Chr 16AR

telomere repeat binding bouquet formation protein 1

Also known as: CCDC79, SPGF60

NCBI Gene: 283847ENSG00000249961UniProt: Q8NA31

Predicted to be involved in homologous chromosome pairing at meiosis and meiotic attachment of telomere to nuclear envelope. Predicted to act upstream of or within double-strand break repair involved in meiotic recombination. Predicted to be located in nuclear inner membrane and shelterin complex. Implicated in spermatogenic failure 60. [provided by Alliance of Genome Resources, Jul 2025]

Population Genetics & Constraint

gnomAD v4 — loss-of-function & missense intolerance

gnomAD
Tolerant — LoF & missense variants common in population
LoF Constraint?LOEUF (Loss-of-function Observed/Expected Upper bound Fraction) is the upper bound of the 90% CI for LoF OE — the preferred gnomAD v4 metric. Lower = more intolerant to LoF. LOEUF < 0.35 = highly constrained.

Typical tolerance to LoF variation

Missense Constraint?Missense Z-score: standard deviations fewer missense variants observed vs. expected. Z > 3.09 (p < 0.001) = gene does not tolerate missense variation. OE missense < 0.6 is also considered constrained.

The highest-scoring mechanism for this gene is dominant-negative.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
