Genes affected

ZNF695 (HGNC:30954): (zinc finger protein 695) 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, DNA-templated. Predicted to be located 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]

ZNF695 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.06).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.895 is higher than 0.05.
