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.

POGZ Gene-Disease associations (from GenCC):

• 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 45 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-151406046-G-A is Pathogenic according to our data. Variant chr1-151406046-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 521279.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

The stop gained variant c.2989C>T (p.Arg997Ter) in POGZ gene has been reported previously in heterozygous state in patient affected with White-Sutton syndrome (Assia Batzir et al., 2020). The c.2989C>T variant is novel (not in any individuals) in gnomAD exomes and 1000 Genomes. This variant has been reported to the ClinVar database as Pathogenic/Likely_pathogenic. This variant is predicted to cause loss of normal protein function through protein truncation. Loss of function variants have been previously reported to be disease causing. The nucleotide change c.2989C>T in POGZ is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The observed variant is present in the last exon. For these reasons, this variant has been classified as Pathogenic -
