SMC2

Chr 9AR

structural maintenance of chromosomes 2

Also known as: CAP-E, CAPE, SMC-2, SMC2L1

NCBI Gene: 10592ENSG00000136824UniProt: O95347

Predicted to enable chromatin binding activity. Involved in mitotic chromosome condensation and positive regulation of chromosome condensation. Located in condensed chromosome; cytoplasm; and nuclear lumen. Part of condensin complex. Implicated in colon adenocarcinoma. Biomarker of colorectal cancer.

Clinical Summary— SMC2
⚡
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 1.00). 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.

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.
