The variant allele was found at a frequency of 0.000046 in 152,012 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.000046 (0 hom., cov: 33)
• Consequence: GNAQ NM_002072.5 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.953

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 Benign. Variant got -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BS2: High AC in GnomAd4 at 7 AD gene.
