Genes affected

ZNF224 (HGNC:13017): (zinc finger protein 224) This gene encodes a member of the Krueppel C2H2-type zinc-finger family of proteins. The encoded protein represses transcription of the aldolase A gene, which encodes a key enzyme in glycolysis. The encoded zinc-finger protein may also function as a transcriptional co-activator with Wilms' tumor protein 1 to regulate apoptotic genes in leukemia. [provided by RefSeq, Jul 2016]

ZNF225-AS1 (HGNC:55916): (ZNF225 and ZNF224 antisense RNA 1)

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.051271617).

Ambry Genetics

Dec 13, 2021

The c.1060A>G (p.I354V) alteration is located in exon 6 (coding exon 4) of the ZNF224 gene. This alteration results from a A to G substitution at nucleotide position 1060, causing the isoleucine (I) at amino acid position 354 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
