Genes affected

ZKSCAN3 (HGNC:13853): (zinc finger with KRAB and SCAN domains 3) Enables DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and chromatin binding activity. Involved in several processes, including negative regulation of autophagy; negative regulation of cellular senescence; and regulation of transcription, DNA-templated. Located in cytoplasm and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.340G>T (p.G114W) alteration is located in exon 3 (coding exon 1) of the ZKSCAN3 gene. This alteration results from a G to T substitution at nucleotide position 340, causing the glycine (G) at amino acid position 114 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
