AKIRIN2

Chr 6

akirin 2

Also known as: C6orf166, FBI1, dJ486L4.2

NCBI Gene: 55122ENSG00000135334UniProt: Q53H80

Enables enzyme binding activity; identical protein binding activity; and protein-macromolecule adaptor activity. Involved in proteasome localization and protein import into nucleus. Acts upstream of with a positive effect on nuclear protein quality control by the ubiquitin-proteasome system. Located in nucleoplasm. Is active in nucleus.

Clinical Summary— AKIRIN2
⚡
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 0.92). One damaged copy is likely sufficient to cause disease.

Population Genetics & Constraint

gnomAD v4 — loss-of-function & missense intolerance

gnomAD
LoF intolerant — likely haploinsufficient
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.

pLI 0.924
Z-score 3.03
OE 0.08 (0.03–0.38)
Highly constrained

More LoF-intolerant than ~75% of genes

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.

Synonymous OE?Control metric — synonymous variants are largely neutral and expected near OE = 1.0. Significant deviation may indicate annotation issues.1.23
