Genes affected
NECTIN2 (HGNC:9707): (nectin cell adhesion molecule 2) This gene encodes a single-pass type I membrane glycoprotein with two Ig-like C2-type domains and an Ig-like V-type domain. This protein is one of the plasma membrane components of adherens junctions. It also serves as an entry for certain mutant strains of herpes simplex virus and pseudorabies virus, and it is involved in cell to cell spreading of these viruses. Variations in this gene have been associated with differences in the severity of multiple sclerosis. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2021The c.124G>A (p.V42M) alteration is located in exon 2 (coding exon 2) of the NECTIN2 gene. This alteration results from a G to A substitution at nucleotide position 124, causing the valine (V) at amino acid position 42 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
