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.

• intellectual disability-microcephaly-strabismus-behavioral abnormalities syndrome

  Inheritance: AD Classification: DEFINITIVE, STRONG, SUPPORTIVE Submitted by: Labcorp Genetics (formerly Invitae), Illumina, G2P, Orphanet, ClinGen

ACMG classification

Our verdict: Pathogenic. The variant received 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 80 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 [Likely_pathogenic]. Clinvar id is 224723.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

The POGZ c.2590C>T; p.Arg864Ter variant (rs756659230, ClinVar Variation ID: 224723) has been reported in an individual with White-Sutton syndrome (Stessman 2016). This variant is absent from the Genome Aggregation Database (v2.1.1), indicating it is not a common polymorphism. This variant induces an early termination codon and is predicted to result in a truncated protein or mRNA subject to nonsense-mediated decay. Based on available information, this variant is considered to be likely pathogenic. References: Stessman HF et al. Disruption of POGZ Is Associated with Intellectual Disability and Autism Spectrum Disorders. Am J Hum Genet. 2016 Mar 3;98(3):541-552. PMID: 26942287. -
