Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 3P and 1B. PM2 PP2 BP4

The NM_015100.4(POGZ):​c.634G>A​(p.Val212Met) variant causes a missense change. The variant allele was found at a frequency of 0.00000274 in 1,461,816 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★).

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 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), POGZ. . Gene score misZ 3.5062 (greater than the threshold 3.09). Trascript score misZ 4.1346 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, autosomal dominant 40, intellectual disability-microcephaly-strabismus-behavioral abnormalities syndrome.
• BP4: Computational evidence support a benign effect (MetaRNN=0.37819222).

Uncertain significance, criteria provided, single submitter	clinical testing;provider interpretation	Geisinger Autism and Developmental Medicine Institute, Geisinger Health System	Aug 30, 2017	This 12 year old male with autism spectrum disorder, anxiety, learning disorder, motor stereotypies, esotropia, myopia, enuresis, and dysmorphic features (particularly midface hypoplasia and a generally flat face) was found to carry a missense variant in the POGZ gene. Inheritance is unknown, as a paternal sample is unavailable. The patient's father is reported to have autistic features. Intellectual disability, autism, dysmorphic features, and vision issues have been seen in individuals with pathogenic variants in POGZ. The p.Val212Met variant is absent from population databases. Computational prediction models are inconsistent. -
