Genes affected

ZNF213 (HGNC:13005): (zinc finger protein 213) C2H2 zinc finger proteins, such as ZNF213, have bipartite structures in which one domain binds DNA or RNA and the other modulates target gene expression.[supplied by OMIM, Apr 2004]

ZNF213-AS1 (HGNC:50505): (ZNF213 antisense RNA 1 (head to head))

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.16713277).

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.439C>T (p.R147W) alteration is located in exon 3 (coding exon 2) of the ZNF213 gene. This alteration results from a C to T substitution at nucleotide position 439, causing the arginine (R) at amino acid position 147 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
