Genes affected

ZNF397 (HGNC:18818): (zinc finger protein 397) This gene encodes a protein with a N-terminal SCAN domain, and the longer isoform contains nine C2H2-type zinc finger repeats in the C-terminal domain. The protein localizes to centromeres during interphase and early prophase, and different isoforms can repress or activate transcription in transfection studies. Multiple transcript variants encoding different isoforms have been found for this gene. Additional variants have been described, but their biological validity has not been determined.

The c.734A>G (p.Q245R) alteration is located in exon 4 (coding exon 3) of the ZNF397 gene. This alteration results from a A to G substitution at nucleotide position 734, causing the glutamine (Q) at amino acid position 245 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
