Genes affected
PLXNA2 (HGNC:9100): (plexin A2) This gene encodes a member of the plexin-A family of semaphorin co-receptors. Semaphorins are a large family of secreted or membrane-bound proteins that mediate repulsive effects on axon pathfinding during nervous system development. A subset of semaphorins are recognized by plexin-A/neuropilin transmembrane receptor complexes, triggering a cellular signal transduction cascade that leads to axon repulsion. This plexin-A family member is thought to transduce signals from semaphorin-3A and -3C. [provided by RefSeq, Jul 2008]

PLXNA2-related disorder Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesSep 24, 2024The PLXNA2 c.5624G>A variant is predicted to result in the amino acid substitution p.Arg1875Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.090% of alleles in individuals of East Asian descent in gnomAD, which may be too common to be an undocumented primary cause of disease. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
