Genes affected

ZNF462 (HGNC:21684): (zinc finger protein 462) The protein encoded by this gene belongs to C2H2-type zinc finger family of proteins. It contains multiple C2H2-type zinc fingers and may be involved in transcriptional regulation. Alternative splicing results in multiple transcript variants encoding different isoforms.

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 9-106923604-G-A is Pathogenic according to our data. Variant chr9-106923604-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 1299321.Status of the report is criteria_provided_single_submitter, 1 stars.
