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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2021The c.1184C>T (p.A395V) alteration is located in exon 7 (coding exon 7) of the TBL2 gene. This alteration results from a C to T substitution at nucleotide position 1184, causing the alanine (A) at amino acid position 395 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
