• Conservation: PhyloP100: 10.0

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]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM1: In a modified_residue 5-glutamyl histamine (size 0) in uniprot entity GNAQ_HUMAN
• PM2: Very rare variant in population databases, with high coverage
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
• PP5: Variant 9-77794572-TG-AA is Pathogenic according to our data. Variant chr9-77794572-TG-AA is described in ClinVar as [Likely_pathogenic]. Clinvar id is 376311.Status of the report is no_assertion_criteria_provided, 0 stars.
