Summaries for ARHGEF6 Gene

Entrez Gene Summary for ARHGEF6 Gene

  • Rho GTPases play a fundamental role in numerous cellular processes that are initiated by extracellular stimuli that work through G protein coupled receptors. The encoded protein belongs to a family of cytoplasmic proteins that activate the Ras-like family of Rho proteins by exchanging bound GDP for GTP. It may form a complex with G proteins and stimulate Rho-dependent signals. This protein is activated by PI3-kinase. Mutations in this gene can cause X-chromosomal non-specific mental retardation.

GeneCards Summary for ARHGEF6 Gene

ARHGEF6 (Rac/Cdc42 Guanine Nucleotide Exchange Factor (GEF) 6) is a Protein Coding gene. Diseases associated with ARHGEF6 include non-syndromic x-linked intellectual disability and borjeson-forssman-lehmann syndrome. Among its related pathways are Signaling by FGFR and RhoGDI Pathway. GO annotations related to this gene include phospholipid binding and Rho guanyl-nucleotide exchange factor activity. An important paralog of this gene is ARHGEF7.

  • Mental retardation, X-linked 46 (MRX46) [MIM:300436]: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. Intellectual deficiency is the only primary symptom of non-syndromic X-linked mental retardation, while syndromic mental retardation presents with associated physical, neurological and/or psychiatric manifestations. Note=The disease is caused by mutations affecting the gene represented in this entry.
