ARHGEF7

Chr 13

Rho guanine nucleotide exchange factor 7

Also known as: BETA-PIX, COOL-1, COOL1, Nbla10314, P50, P50BP, P85, P85COOL1

The protein acts as a RAC1 guanine nucleotide exchange factor that regulates cell migration, attachment, and synaptic development in hippocampal neurons. Mutations cause autosomal dominant intellectual disability with epilepsy and abnormal behavior, typically presenting in early childhood. This gene is highly constrained against loss-of-function variants (pLI = 1.0, LOEUF = 0.19), indicating intolerance to protein-disrupting mutations.

Clinical SummaryARHGEF7
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.
