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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2022The c.26C>T (p.P9L) alteration is located in exon 1 (coding exon 1) of the PLXNC1 gene. This alteration results from a C to T substitution at nucleotide position 26, causing the proline (P) at amino acid position 9 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
