Genes affected

ZNF670 (HGNC:28167): (zinc finger protein 670) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ZNF670-ZNF695 (HGNC:49200): (ZNF670-ZNF695 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring zinc finger protein 670 (ZNF670) and zinc finger protein 695 (ZNF695) genes on chromosome 1. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2011]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
