Genes affected

PLXNC1 (HGNC:9106): (plexin C1) This gene encodes a member of the plexin family. Plexins are transmembrane receptors for semaphorins, a large family of proteins that regulate axon guidance, cell motility and migration, and the immune response. The encoded protein and its ligand regulate melanocyte adhesion, and viral semaphorins may modulate the immune response by binding to this receptor. The encoded protein may be a tumor suppressor protein for melanoma. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Jan 2011]

The c.280G>A (p.A94T) alteration is located in exon 1 (coding exon 1) of the PLXNC1 gene. This alteration results from a G to A substitution at nucleotide position 280, causing the alanine (A) at amino acid position 94 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
