Genes affected

UBXN2A (HGNC:27265): (UBX domain protein 2A) Predicted to enable ubiquitin binding activity. Predicted to be involved in several processes, including autophagosome assembly; nuclear membrane reassembly; and proteasome-mediated ubiquitin-dependent protein catabolic process. Predicted to act upstream of or within cellular response to leukemia inhibitory factor; regulation of gene expression; and regulation of protein metabolic process. Predicted to be located in cis-Golgi network and endoplasmic reticulum. Predicted to be active in cytosol and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Jan 26, 2022

The c.334G>A (p.D112N) alteration is located in exon 5 (coding exon 4) of the UBXN2A gene. This alteration results from a G to A substitution at nucleotide position 334, causing the aspartic acid (D) at amino acid position 112 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
