NM_173658.4:c.233A>G

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_173658.4(ZNF660):​c.233A>G​(p.Tyr78Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000192 in 1,613,936 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Y78F) has been classified as Uncertain significance.

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)
