KDM7A

Chr 7

lysine demethylase 7A

Also known as: JHDM1D

NCBI Gene: 80853ENSG00000006459UniProt: Q6ZMT4

Enables histone demethylase activity; methylated histone binding activity; and transition metal ion binding activity. Predicted to be involved in chromatin remodeling; midbrain development; and regulation of transcription by RNA polymerase II. Located in nucleolus and nucleoplasm. Implicated in melanoma.

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.

pLI 1.000

OE 0.12 (0.06–0.23)
Highly constrained

Highly LoF-intolerant (top ~10% 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.
