INPP5J

Chr 22

inositol polyphosphate-5-phosphatase J

Also known as: INPP5, PIB5PA, PIPP

Predicted to enable inositol trisphosphate phosphatase activity; phosphatidylinositol-3,4,5-trisphosphate 5-phosphatase activity; and phosphatidylinositol-4,5-bisphosphate 5-phosphatase activity. Predicted to be involved in negative regulation of microtubule polymerization. Predicted to act upstream of or within negative regulation of neuron projection development and negative regulation of peptidyl-serine phosphorylation. Located in cytoplasm and ruffle.

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

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.

Observed / Expected Ratios?Shaded band = 90% confidence interval. Vertical tick = point estimate. Grey threshold line = gnomAD constraint cutoff for that variant class.
