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 undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-151406941-A-AG is Pathogenic according to our data. Variant chr1-151406941-A-AG is described in ClinVar as [Likely_pathogenic]. Clinvar id is 207801.Status of the report is criteria_provided_single_submitter, 1 stars.

c.2514dupC: p.Ser839LeufsX25 in exon 17 in the POGZ Gene (NM_015100.3). The normal sequence with the base that is duplicated in braces is: ACCC{C}TCTC. The c.2514dupC variant in the POGZ gene causes a frameshift starting with codon Serine 839, changes this amino acid to a Leucine residue and creates a premature Stop codon at position 25 of the new reading frame, denoted p.Ser839LeufsX25. This variant is predicted to cause loss of normal protein function through protein truncation. The c.2514dupC variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The c.2514dupC variant is a good candidate for a pathogenic variant, however the possibility it may be a rare benign variant cannot be excluded. -
