Genes affected

TBL2 (HGNC:11586): (transducin beta like 2) This gene encodes a member of the beta-transducin protein family. Most proteins of the beta-transducin family are involved in regulatory functions. This protein is possibly involved in some intracellular signaling pathway. This gene is deleted in Williams-Beuren syndrome, a developmental disorder caused by deletion of multiple genes at 7q11.23.

The c.875G>A (p.R292Q) alteration is located in exon 6 (coding exon 6) of the TBL2 gene. This alteration results from a G to A substitution at nucleotide position 875, causing the arginine (R) at amino acid position 292 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
