TMEM168

Chr 7

transmembrane protein 168

Enables sodium channel regulator activity. Predicted to act upstream of or within regulation of ubiquitin-dependent protein catabolic process and regulation of voltage-gated sodium channel activity. Located in nuclear membrane and transport vesicle. [provided by Alliance of Genome Resources, Apr 2025]

Population Genetics & Constraint

gnomAD v4 — loss-of-function & missense intolerance

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.

OE 0.36 (0.210.65)
Tolerant

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.
