Genes affected

SHFL (HGNC:25649): (shiftless antiviral inhibitor of ribosomal frameshifting) This gene is an interferon stimulated gene (ISG) that inhibits viral replication. The encoded protein binds nucleic acids and inhibits programmed -1 ribosomal frameshifting required for translation by many RNA viruses. Viruses inhibited by the protein include Zika virus, dengue virus and the coronaviruses, SARS-CoV and SARS-CoV2. [provided by RefSeq, Aug 2021]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.4009729).

The c.467C>A (p.P156Q) alteration is located in exon 6 (coding exon 6) of the C19orf66 gene. This alteration results from a C to A substitution at nucleotide position 467, causing the proline (P) at amino acid position 156 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
