SPOUT1

Chr 9AR

SPOUT domain containing methyltransferase 1

Also known as: C9orf114, CENP-32, CENP32, HSPC109, NEDGSB

NCBI Gene: 51490ENSG00000198917UniProt: Q5T280

Enables miRNA binding activity. Involved in maintenance of centrosome location and miRNA processing. Acts upstream of with a positive effect on post-transcriptional regulation of gene expression. Located in kinetochore; mitotic spindle; and spindle pole centrosome. [provided by Alliance of Genome Resources, Apr 2025]

Population Constraint (gnomAD)
Low constraint (pLI 0.00) — loss-of-function variants are relatively tolerated in the population.

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.

Highly tolerant — LoF variants common in population

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.
