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.187G>A (p.G63R) alteration is located in exon 2 (coding exon 2) of the CNKSR1 gene. This alteration results from a G to A substitution at nucleotide position 187, causing the glycine (G) at amino acid position 63 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
