Genes affected
NTN1 (HGNC:8029): (netrin 1) Netrin is included in a family of laminin-related secreted proteins. The function of this gene has not yet been defined; however, netrin is thought to be involved in axon guidance and cell migration during development. Mutations and loss of expression of netrin suggest that variation in netrin may be involved in cancer development. [provided by RefSeq, Jul 2008]

The c.235G>A (p.V79M) alteration is located in exon 2 (coding exon 1) of the NTN1 gene. This alteration results from a G to A substitution at nucleotide position 235, causing the valine (V) at amino acid position 79 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
