Genes affected

CNKSR1 (HGNC:19700): (connector enhancer of kinase suppressor of Ras 1) This gene encodes a protein containing several motifs involved in protein-protein interaction, including PDZ, PH (Pleckstrin homology), and SAM (sterile alpha motif) domains. The encoded protein acts as a scaffold component for receptor tyrosine kinase signaling and may mediate crosstalk between different signaling pathways. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

The c.673G>C (p.V225L) alteration is located in exon 7 (coding exon 7) of the CNKSR1 gene. This alteration results from a G to C substitution at nucleotide position 673, causing the valine (V) at amino acid position 225 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
