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]

The c.369G>T (p.E123D) alteration is located in exon 2 (coding exon 1) of the TOB1 gene. This alteration results from a G to T substitution at nucleotide position 369, causing the glutamic acid (E) at amino acid position 123 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
