Genes affected
ZNF660 (HGNC:26720): (zinc finger protein 660) This gene encodes a protein that contains multiple C2H2 zinc finger domains, and is located in a cluster of zinc-finger encoding genes on chromosome 3. Naturally-occurring readthrough transcription is observed between this gene and the downstream zinc finger protein 197 gene and is represented by GeneID:110354863. [provided by RefSeq, May 2017]
ZNF197 (HGNC:12988): (zinc finger protein 197) This gene product belongs to the zinc finger protein superfamily, members of which are regulatory proteins characterized by nucleic acid-binding zinc finger domains. The encoded protein contains 20 tandemly arrayed C2H2-type zinc fingers, a Kruppel-associated box (KRAB) domain, and a SCAN box. This transcript turns over rapidly and contains 3' UTR AUUUA motifs, which are often a hallmark of rapid turnover. It is overexpressed in some thyroid papillary carcinomas. This gene is located in a cluster of zinc finger genes at 3p21. Naturally-occurring readthrough transcription is observed between this gene and the upstream zinc finger protein 660 gene and is represented by GeneID:110354863. [provided by RefSeq, May 2017]
ZKSCAN7-AS1 (HGNC:53964): (ZKSCAN7 ZNF cluster antisense RNA 1)

The c.716T>G (p.L239R) alteration is located in exon 3 (coding exon 1) of the ZNF660 gene. This alteration results from a T to G substitution at nucleotide position 716, causing the leucine (L) at amino acid position 239 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
