Genes affected

VPREB3 (HGNC:12710): (V-set pre-B cell surrogate light chain 3) The protein encoded by this gene is the human ortholog of the mouse VpreB3 (8HS20) protein, is thought to be involved in B-cell maturation, and may play a role in assembly of the pre-B cell receptor (pre-BCR). While the role of this protein in B-cell development has not yet been elucidated, studies with the chicken ortholog of this protein have found that when overexpressed, this protein localizes to the endoplasmic reticulum. The mouse ortholog of this protein has been shown to associate with membrane mu heavy chains early in the course of pre-B cell receptor biosynthesis. Expression of this gene has been observed in some lymphomas. [provided by RefSeq, Apr 2015]

The c.179G>A (p.R60Q) alteration is located in exon 2 (coding exon 2) of the VPREB3 gene. This alteration results from a G to A substitution at nucleotide position 179, causing the arginine (R) at amino acid position 60 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
