Genes affected

ZFPM2 (HGNC:16700): (zinc finger protein, FOG family member 2) The zinc finger protein encoded by this gene is a widely expressed member of the FOG family of transcription factors. The family members modulate the activity of GATA family proteins, which are important regulators of hematopoiesis and cardiogenesis in mammals. It has been demonstrated that the protein can both activate and down-regulate expression of GATA-target genes, suggesting different modulation in different promoter contexts. A related mRNA suggests an alternatively spliced product but this information is not yet fully supported by the sequence. [provided by RefSeq, Jul 2008]

ZFPM2-AS1 (HGNC:50698): (ZFPM2 antisense RNA 1)

ACMG classification

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 8-105561361-A-C is Pathogenic according to our data. Variant chr8-105561361-A-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 3356187.Status of the report is no_assertion_criteria_provided, 0 stars.
