PRRC2B

Chr 9

proline rich coiled-coil 2B

The protein enables RNA binding and is involved in cell differentiation and embryonic development. Mutations cause autosomal dominant neurodevelopmental disorder through loss-of-function mechanisms. The gene is highly intolerant to loss-of-function variants, consistent with severe developmental consequences when disrupted.

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.
Some data sources returned errors (1)
