Genes affected

PTK6 (HGNC:9617): (protein tyrosine kinase 6) The protein encoded by this gene is a cytoplasmic nonreceptor protein kinase which may function as an intracellular signal transducer in epithelial tissues. Overexpression of this gene in mammary epithelial cells leads to sensitization of the cells to epidermal growth factor and results in a partially transformed phenotype. Expression of this gene has been detected at low levels in some breast tumors but not in normal breast tissue. The encoded protein has been shown to undergo autophosphorylation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2012]

The c.934G>A (p.D312N) alteration is located in exon 6 (coding exon 6) of the PTK6 gene. This alteration results from a G to A substitution at nucleotide position 934, causing the aspartic acid (D) at amino acid position 312 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
