RALGPS1

Chr 9

Ral GEF with PH domain and SH3 binding motif 1

Also known as: RALGEF2, RALGPS1A

The protein functions as a guanine nucleotide exchange factor for the small GTPase RALA and is involved in cytoskeletal organization. Loss-of-function mutations in RALGPS1 cause autosomal dominant neurodevelopmental disorder, as the gene is highly intolerant to loss-of-function variation (pLI=1.0, LOEUF=0.127). The pathogenic mechanism involves haploinsufficiency affecting Ral protein signal transduction pathways critical for normal neuronal development.

Clinical SummaryRALGPS1
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.
