Variant summary

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

The NR_026947.1(C1RL-AS1):​n.5012+180G>A variant causes a intron, non coding transcript change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0677 in 152,262 control chromosomes in the GnomAD database, including 458 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 0.068 (458 hom., cov: 32)
• Consequence: C1RL-AS1 NR_026947.1 intron, non_coding_transcript
• Clinical Significance: Not reported in ClinVar

Genes affected

C1RL-AS1 (HGNC:27461): (C1RL antisense RNA 1)

RBP5 (HGNC:15847): (retinol binding protein 5) The protein encoded by this gene is a cellular retinol-binding protein expressed highly in kidney and liver. Down-regulation of the encoded protein in hepatocellular carcinoma was associated with large tumor size and poor patient survival rates. [provided by RefSeq, Jul 2016]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.162 is higher than 0.05.
