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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1022C>T (p.P341L) alteration is located in exon 7 (coding exon 5) of the ZKSCAN3 gene. This alteration results from a C to T substitution at nucleotide position 1022, causing the proline (P) at amino acid position 341 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
