Genes affected

DCC (HGNC:2701): (DCC netrin 1 receptor) This gene encodes a netrin 1 receptor. The transmembrane protein is a member of the immunoglobulin superfamily of cell adhesion molecules, and mediates axon guidance of neuronal growth cones towards sources of netrin 1 ligand. The cytoplasmic tail interacts with the tyrosine kinases Src and focal adhesion kinase (FAK, also known as PTK2) to mediate axon attraction. The protein partially localizes to lipid rafts, and induces apoptosis in the absence of ligand. The protein functions as a tumor suppressor, and is frequently mutated or downregulated in colorectal cancer and esophageal carcinoma. [provided by RefSeq, Oct 2009]

The DCC p.Pro1359Leu variant was not identified in the literature nor was it identified in ClinVar, Cosmic or LOVD 3.0. The variant was identified in dbSNP (ID: rs750334840) and in control databases in 9 of 251472 chromosomes at a frequency of 0.000036 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 2 of 16256 chromosomes (freq: 0.000123), East Asian in 1 of 18394 chromosomes (freq: 0.000054), European (non-Finnish) in 5 of 113758 chromosomes (freq: 0.000044) and Latino in 1 of 34582 chromosomes (freq: 0.000029); it was not observed in the Ashkenazi Jewish, European (Finnish), Other, and South Asian populations. The p.Pro1359 residue is conserved across mammals and other organisms, and four out of five computational analyses (PolyPhen-2, SIFT, BLOSUM, MutationTaster) suggest that the variant may impact the protein; however, this information is not predictive enough to assume pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
