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 12 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 60 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-151406445-G-A is Pathogenic according to our data. Variant chr1-151406445-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 224723.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr1-151406445-G-A is described in Lovd as [Pathogenic].
