The variant allele was found at a frequency of 0.000139 in 151,462 control chromosomes in the GnomAD database, including 1 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 0.00014 (1 hom., cov: 29)
• Consequence: SOX2-OT NR_075091.1 intron, non_coding_transcript
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.617

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.
