Genes affected

ZNF19 (HGNC:12981): (zinc finger protein 19) The protein encoded by this gene contains a zinc finger, a nucleic acid-binding domain present in many transcription factors. This gene is located in a region next to ZNF23, a gene also encoding a zinc finger protein, on chromosome 16. [provided by RefSeq, Jul 2008]

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=0.049393535).

The c.331A>G (p.R111G) alteration is located in exon 6 (coding exon 4) of the ZNF19 gene. This alteration results from a A to G substitution at nucleotide position 331, causing the arginine (R) at amino acid position 111 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
