GLYR1

Chr 16

glyoxylate reductase 1 homolog

Also known as: BM045, HIBDL, N-PAC, NP60, NPAC, hNDF

NCBI Gene: 84656ENSG00000140632UniProt: Q49A26

Enables several functions, including chromatin-protein adaptor activity; methylated histone binding activity; and nucleosome binding activity. Involved in transcription elongation-coupled chromatin remodeling and transcription initiation-coupled chromatin remodeling. Located in cytosol and nucleoplasm. Part of nucleosome. Is active in chromatin. [provided by Alliance of Genome Resources, Apr 2025]

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.

OE 0.06 (0.02–0.20)
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.
