Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_006529.4(GLRA3):​c.200-8087A>G variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.38 in 151,998 control chromosomes in the GnomAD database, including 11,192 homozygotes. 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 0.38 (11192 hom., cov: 33)
• Consequence: GLRA3 NM_006529.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.678

Genes affected

GLRA3 (HGNC:4328): (glycine receptor alpha 3) This gene encodes a member of the ligand-gated ion channel protein family. The encoded protein is a member of the glycine receptor subfamily. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2013]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.455 is higher than 0.05.
