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]

ZNF660-ZNF197 links:

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]

The c.681C>A (p.F227L) alteration is located in exon 3 (coding exon 1) of the ZNF660 gene. This alteration results from a C to A substitution at nucleotide position 681, causing the phenylalanine (F) at amino acid position 227 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
