Genes affected

ZNF75D (HGNC:13145): (zinc finger protein 75D) This gene encodes a protein that likely functions as a transcription factor. The protein, which belongs to the ZNF75 family, includes an N-terminal SCAN domain, a KRAB box, and five C2H2-type zinc finger motifs. Another functional gene belonging to this family is located on chromosome 16, while pseudogenes have been identified on chromosomes 11 and 12. Alternative splicing results in multiple transcripts variants. [provided by RefSeq, Jun 2010]

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=0.10990521).

Collection Method: clinical testing

The c.887A>G (p.Q296R) alteration is located in exon 6 (coding exon 5) of the ZNF75D gene. This alteration results from a A to G substitution at nucleotide position 887, causing the glutamine (Q) at amino acid position 296 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
