Genes affected

ZNF628 (HGNC:28054): (zinc finger protein 628) Zinc finger proteins (ZNFs), which bind nucleic acids, perform many key functions, the most important of which is regulating transcription. See ZNF91 (MIM 603971) for general information on ZNFs.[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.16473138).

The c.1932C>A (p.N644K) alteration is located in exon 3 (coding exon 1) of the ZNF628 gene. This alteration results from a C to A substitution at nucleotide position 1932, causing the asparagine (N) at amino acid position 644 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
