PRUNE1

Chr 1AR

prune exopolyphosphatase 1

Also known as: DRES-17, DRES17, H-PRUNE, HTCD37, NMIHBA, PRUNE

The protein functions as a phosphodiesterase with higher activity toward cAMP than cGMP and regulates neurogenesis and microtubule polymerization. Mutations cause autosomal recessive neurodevelopmental disorder with microcephaly, hypotonia, and variable brain anomalies. The gene shows moderate constraint against loss-of-function variants (LOEUF 0.661), consistent with its role in early neurodevelopment.

Population Constraint (gnomAD)
Low constraint (pLI 0.01) — loss-of-function variants are relatively tolerated in the population.

The Badonyi & Marsh prediction model was trained exclusively on dominant disease genes. Predictions are not reliable for genes with autosomal recessive inheritance and are shown at reduced opacity for reference only.
