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]

Collection Method:clinical testing

The c.121C>G (p.P41A) alteration is located in exon 2 (coding exon 2) of the ZFPM2 gene. This alteration results from a C to G substitution at nucleotide position 121, causing the proline (P) at amino acid position 41 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 41 of the ZFPM2 protein (p.Pro41Ala). This variant is present in population databases (rs199535268, gnomAD 0.03%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with ZFPM2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1061068). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
