Genes affected

POGZ (HGNC:18801): (pogo transposable element derived with ZNF domain) The protein encoded by this gene appears to be a zinc finger protein containing a transposase domain at the C-terminus. This protein was found to interact with the transcription factor SP1 in a yeast two-hybrid system. Alternatively spliced transcript variants encoding distinct isoforms have been observed.

ACMG classification

Verdict is Pathogenic. Variant got 18 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. There are 21 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-151406387-TTG-T is Pathogenic according to our data. Variant chr1-151406387-TTG-T is described in ClinVar as [Pathogenic]. Clinvar id is 559853.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Pathogenic, criteria provided, single submitter	clinical testing	3billion	Feb 23, 2023	The variant is not observed in the gnomAD v2.1.1 dataset. This variant was predicted to result in a loss or disruption of normal protein function through protein truncation. Multiple pathogenic variants are reported in the predicted truncated region. The variant has been reported to be associated with POGZ-related disorder (ClinVar ID: VCV000559853). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -
