Genes affected

ZNF445 (HGNC:21018): (zinc finger protein 445) Enables double-stranded methylated DNA binding activity. Involved in maintenance of DNA methylation and regulation of genetic imprinting. Located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.0946 CDS is truncated, and there are 0 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
