Chr 9AR

shortage in chiasmata 1

Also known as: C9orf84, MZIP2, SPGF75, ZIP2, ZIP2H

Enables ATP hydrolysis activity and single-stranded DNA binding activity. Predicted to be involved in resolution of meiotic recombination intermediates and synaptonemal complex assembly. Predicted to be located in chromosome. Predicted to be active in condensed nuclear chromosome. Implicated in spermatogenic failure 75. [provided by Alliance of Genome Resources, Jul 2025]

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.

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.

Observed / Expected Ratios?Shaded band = 90% confidence interval. Vertical tick = point estimate. Grey threshold line = gnomAD constraint cutoff for that variant class.
LoF OE?Ratio of observed to expected LoF variants. Upper CI bound (LOEUF) ≤ 0.35 = strong LoF constraint signal.0.66 (0.520.85)

Synonymous OE?Control metric — synonymous variants are largely neutral and expected near OE = 1.0. Significant deviation may indicate annotation issues.0.81
