Genes affected

TOB1 (HGNC:11979): (transducer of ERBB2, 1) This gene encodes a member of the transducer of erbB-2 /B-cell translocation gene protein family. Members of this family are anti-proliferative factors that have the potential to regulate cell growth. The encoded protein may function as a tumor suppressor. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Aug 2011]

Collection Method:clinical testing

The c.239A>T (p.D80V) alteration is located in exon 2 (coding exon 1) of the TOB1 gene. This alteration results from a A to T substitution at nucleotide position 239, causing the aspartic acid (D) at amino acid position 80 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
