Genes affected

GNAQ (HGNC:4390): (G protein subunit alpha q) This locus encodes a guanine nucleotide-binding protein. The encoded protein, an alpha subunit in the Gq class, couples a seven-transmembrane domain receptor to activation of phospolipase C-beta. Mutations at this locus have been associated with problems in platelet activation and aggregation. A related pseudogene exists on chromosome 2.[provided by RefSeq, Nov 2010]

GNAQ Gene-Disease associations (from GenCC):

• congenital hemangioma

  Inheritance: AD Classification: STRONG Submitted by: G2P
• Sturge-Weber syndrome
