Genes affected

ZHX3 (HGNC:15935): (zinc fingers and homeoboxes 3) This gene encodes a member of the zinc fingers and homeoboxes (ZHX) gene family. The encoded protein contains two C2H2-type zinc fingers and five homeodomains and forms a dimer with itself or with zinc fingers and homeoboxes family member 1. In the nucleus, the dimerized protein interacts with the A subunit of the ubiquitous transcription factor nuclear factor-Y and may function as a transcriptional repressor.

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 847 of the ZHX3 protein (p.Arg847Gln). This variant is present in population databases (rs191475189, gnomAD 0.006%). This missense change has been observed in individual(s) with hypertriglyceridemia (PMID: 22135386). This variant is also known as c.2918G>A. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -
