Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BP4 BA1

The NR_075091.1(SOX2-OT):​n.782+6744C>G 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 0.198 in 152,074 control chromosomes in the GnomAD database, including 4,144 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 0.20 (4144 hom., cov: 33)
• Consequence: SOX2-OT NR_075091.1 intron, non_coding_transcript
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 2.22

Genes affected

SOX2-OT (HGNC:20209): (SOX2 overlapping transcript) This gene produces alternatively spliced long non-coding RNAs. These RNAs were observed to be upregulated in tumor cells and positively correlated to expression of the SRY-box 2 gene. Overexpression of these transcripts may promote cell proliferation.

(HGNC:):

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.17).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.377 is higher than 0.05.
