MPRIP

Chr 17

myosin phosphatase Rho interacting protein

Also known as: M-RIP, MRIP, RHOIP3, RIP3, p116Rip

The protein targets myosin phosphatase to the actin cytoskeleton and is required for regulation of the actin cytoskeleton by RhoA and ROCK1. Mutations cause autosomal dominant neurodevelopmental disorder with hypotonia and variable intellectual disability. This gene is highly constrained against loss-of-function variants (pLI = 0.98), indicating that complete protein loss is likely incompatible with normal development.

Clinical SummaryMPRIP
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 0.98). One damaged copy is likely sufficient to cause disease.
