Variant chr15-40176664-C-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 0P and 0B.

The NM_001211.6(BUB1B):c.572C>A(p.Ser191Tyr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000041 in 1,461,730 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. S191S) has been classified as Likely benign.

Genes affected

BUB1B (HGNC:1149): (BUB1 mitotic checkpoint serine/threonine kinase B) This gene encodes a kinase involved in spindle checkpoint function. The protein has been localized to the kinetochore and plays a role in the inhibition of the anaphase-promoting complex/cyclosome (APC/C), delaying the onset of anaphase and ensuring proper chromosome segregation. Impaired spindle checkpoint function has been found in many forms of cancer. [provided by RefSeq, Jul 2008]

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. 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 disruptive. ClinVar contains an entry for this variant (Variation ID: 1018650). This variant has not been reported in the literature in individuals affected with BUB1B-related conditions. This variant is present in population databases (rs587778145, gnomAD 0.007%). This sequence change replaces serine, which is neutral and polar, with tyrosine, which is neutral and polar, at codon 191 of the BUB1B protein (p.Ser191Tyr). -
