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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2022The c.815A>C (p.K272T) alteration is located in exon 2 (coding exon 1) of the TOB1 gene. This alteration results from a A to C substitution at nucleotide position 815, causing the lysine (K) at amino acid position 272 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
