Genes affected

ZNF717 (HGNC:29448): (zinc finger protein 717) This gene encodes a Kruppel-associated box (KRAB) zinc-finger protein, which belongs to a large group of transcriptional regulators in mammals. These proteins bind nucleic acids and play important roles in various cellular functions, including cell proliferation, differentiation and apoptosis, and in regulating viral replication and transcription. A pseudogene of this gene was identified on chromosome 1. [provided by RefSeq, May 2016]

LINC00960 (HGNC:48710): (long intergenic non-protein coding RNA 960)

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.013648868).

This sequence change replaces AA1 with AA2 at codon 63 of the ZNF717 protein (p.His63Leu). The AA1 residue is AA_CONSERV conserved and there is a PHYSIOCHEM_SIZE physicochemical difference between AA1 and AA2. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant has not been reported in the literature in individuals with ZNF717-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "SIFT_OUTPUT"; PolyPhen-2: "Benign"; Align-GVGD: "Class ALIGN_GVGD_OUTPUT. The AA2 amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
