The variant allele was found at a frequency of 0.467 in 150,052 control chromosomes in the GnomAD database, including 16,344 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 0.47 (16344 hom., cov: 28)
• Consequence: GDA NM_004293.5 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 1.05

Genes affected

GDA (HGNC:4212): (guanine deaminase) This gene encodes an enzyme responsible for the hydrolytic deamination of guanine. Studies in rat ortholog suggest this gene plays a role in microtubule assembly. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.93).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.531 is higher than 0.05.
