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 undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-151408150-CAGAG-C is Pathogenic according to our data. Variant chr1-151408150-CAGAG-C is described in ClinVar as [Pathogenic]. Clinvar id is 218146.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-151408150-CAGAG-C is described in Lovd as [Pathogenic].
