RGS19

Chr 20

regulator of G protein signaling 19

Also known as: GAIP, RGSGAIP

The protein functions as a regulator of G-protein signaling by increasing GTPase activity of G protein alpha subunits, thereby terminating G protein-mediated cellular signaling pathways. Mutations cause autosomal dominant neurodevelopmental disorders with intellectual disability and developmental delay. This gene is highly constrained against loss-of-function variants (pLI 0.96, LOEUF 0.30), indicating that complete protein loss is likely incompatible with normal development.

Clinical SummaryRGS19
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 0.96). One damaged copy is likely sufficient to cause disease.
