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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.881C>T (p.P294L) alteration is located in exon 10 (coding exon 10) of the CNKSR1 gene. This alteration results from a C to T substitution at nucleotide position 881, causing the proline (P) at amino acid position 294 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
