DIS3L2

Chr 2AR

DIS3 like 3'-5' exoribonuclease 2

Also known as: FAM6A, PRLMNS, hDIS3L2

DIS3L2 encodes a 3'-5'-exoribonuclease that degrades polyuridylated RNAs, including mRNAs and miRNAs, and is essential for proper mitosis and cell proliferation regulation. Biallelic mutations cause Perlman syndrome, an autosomal recessive overgrowth disorder with neonatal onset. This gene is highly constrained against loss-of-function variants in the population.

Definitive — sufficient evidence for diagnostic panels

Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 0.94). One damaged copy is likely sufficient to cause disease.
