Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_004326.4(BCL9):c.1529T>G(p.Val510Gly) variant causes a missense change. The variant allele was found at a frequency of 0.00000752 in 1,461,810 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V510A) has been classified as Uncertain significance.

Genes affected

BCL9 (HGNC:1008): (BCL9 transcription coactivator) BCL9 is associated with B-cell acute lymphoblastic leukemia. It may be a target of translocation in B-cell malignancies with abnormalities of 1q21. Its function is unknown. The overexpression of BCL9 may be of pathogenic significance in B-cell malignancies. [provided by RefSeq, Jul 2008]

The c.1529T>G (p.V510G) alteration is located in exon 8 (coding exon 5) of the BCL9 gene. This alteration results from a T to G substitution at nucleotide position 1529, causing the valine (V) at amino acid position 510 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
