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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2023The c.740T>C (p.I247T) alteration is located in exon 4 (coding exon 3) of the ZNF397 gene. This alteration results from a T to C substitution at nucleotide position 740, causing the isoleucine (I) at amino acid position 247 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
