Genes affected
ZKSCAN1 (HGNC:13101): (zinc finger with KRAB and SCAN domains 1) This gene encodes a member of the Kruppel C2H2-type zinc-finger family of proteins. This encoded protein may function as a transcription factor that regulates the expression of GABA type-A receptors in the brain. Transcripts from this gene have been shown to form stable and abundant circular RNAs. Elevated expression of this gene has been observed in gastric cancer and the encoded protein may stimulate migration and invasion of human gastric cancer cells. [provided by RefSeq, Oct 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2022The c.257G>A (p.R86Q) alteration is located in exon 2 (coding exon 1) of the ZKSCAN1 gene. This alteration results from a G to A substitution at nucleotide position 257, causing the arginine (R) at amino acid position 86 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
