Genes affected

UBXN2B (HGNC:27035): (UBX domain protein 2B) Predicted to enable ubiquitin binding activity. Involved in establishment of mitotic spindle orientation; negative regulation of protein localization to centrosome; and positive regulation of mitotic centrosome separation. Predicted to be located in Golgi apparatus; endoplasmic reticulum; and spindle pole centrosome. Predicted to be active in cytosol and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.22G>C (p.E8Q) alteration is located in exon 1 (coding exon 1) of the UBXN2B gene. This alteration results from a G to C substitution at nucleotide position 22, causing the glutamic acid (E) at amino acid position 8 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
