Genes affected

TBL3 (HGNC:11587): (transducin beta like 3) The protein encoded by this gene has sequence similarity with members of the WD40 repeat-containing protein family. The WD40 group is a large family of proteins, which appear to have a regulatory function. It is believed that the WD40 repeats mediate protein-protein interactions and members of the family are involved in signal transduction, RNA processing, gene regulation, vesicular trafficking, cytoskeletal assembly and may play a role in the control of cytotypic differentiation. This gene has multiple polyadenylation sites. It might have multiple alternatively spliced transcript variants but the variants have not been fully described yet. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.97G>A (p.D33N) alteration is located in exon 3 (coding exon 3) of the TBL3 gene. This alteration results from a G to A substitution at nucleotide position 97, causing the aspartic acid (D) at amino acid position 33 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
