Genetic Variant NM_001077619.2:c.24G>C (chr8-58411409-G-C) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001077619.2(UBXN2B):c.24G>C(p.Glu8Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000708 in 1,270,328 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely benign in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E8Q) has been classified as Uncertain significance.

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]
