Genes affected

STAP2 (HGNC:30430): (signal transducing adaptor family member 2) This gene encodes the substrate of breast tumor kinase, an Src-type non-receptor tyrosine kinase. The encoded protein possesses domains and several tyrosine phosphorylation sites characteristic of adaptor proteins that mediate the interactions linking proteins involved in signal transduction pathways. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.826C>T (p.P276S) alteration is located in exon 9 (coding exon 9) of the STAP2 gene. This alteration results from a C to T substitution at nucleotide position 826, causing the proline (P) at amino acid position 276 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
