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]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -10 ACMG points.

PM1

In a domain Fibronectin type-III 3 (size 93) in uniprot entity DCC_HUMAN there are 5 pathogenic changes around while only 2 benign (71%) in NM_005215.4

BP4

Computational evidence support a benign effect (MetaRNN=0.017723113).

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00272 (414/152330) while in subpopulation NFE AF= 0.00466 (317/68022). AF 95% confidence interval is 0.00424. There are 4 homozygotes in gnomad4. There are 185 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

BS2

High Homozygotes in GnomAd4 at 4 AD,AR gene
