MOSMO

Chr 16

modulator of smoothened

Also known as: ATTHOG, BC030336, C16orf52

NCBI Gene: 730094ENSG00000185716UniProt: Q8NHV5

Predicted to be involved in negative regulation of smoothened signaling pathway; regulation of neuron differentiation; and regulation of protein stability. Predicted to act upstream of or within several processes, including chordate embryonic development; embryonic limb morphogenesis; and smoothened signaling pathway. Predicted to be located in plasma membrane. Predicted to be active in Golgi apparatus and ciliary membrane. [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.

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.
