Genes affected
ZSCAN21 (HGNC:13104): (zinc finger and SCAN domain containing 21) Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in positive regulation of transcription by RNA polymerase II. Predicted to be located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]
ZNF3 (HGNC:13089): (zinc finger protein 3) Enables identical protein binding activity. Predicted to be involved in negative regulation of transcription by RNA polymerase II. Predicted to be located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

The c.890G>C (p.R297T) alteration is located in exon 4 (coding exon 3) of the ZSCAN21 gene. This alteration results from a G to C substitution at nucleotide position 890, causing the arginine (R) at amino acid position 297 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
