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 51 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-151406284-T-TG is Pathogenic according to our data. Variant chr1-151406284-T-TG is described in ClinVar as [Pathogenic]. Clinvar id is 207797.Status of the report is criteria_provided_single_submitter, 1 stars.

The c.2750dupC variant in the POGZ gene has been published as a pathogenic variant associated with POGZ-related disorders (Ye et al., 2015). The c.2750dupC variant causes a frameshift starting with codon Proline 918, changes this amino acid to a Threonine residue, and creates a premature Stop codon at position 26 of the new reading frame, denoted p.Pro918ThrfsX26. This variant is predicted to cause loss of normal protein function through protein truncation. The c.2750dupC variant was not observed in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. We interpret c.2750dupC as a pathogenic variant. -
