Nature of Mutation

DNA sequencing using the SOLiD technique identified an A to T transversion at position 4964 of the Plxna4 transcript in exon 21 of 32 total exons. Two transcripts of the Plxna4 gene are displayed on Ensembl. The mutated nucleotide causes an aspartic acid to valine substitution at amino acid 1330 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction

The Plxna4 gene encodes an 1893 amino acid single-pass type I membrane protein that forms a receptor complex with neuropilin-1 and can propagate semaphorin-3A elicited inhibitory signals into cells and neurons. The protein is widely expressed in the peripheral and central nervous system. It contains four immunoglobulin-like IPT/TIG 1 domains, three PSI (plexin/semaphorin/integrin) domains and one Sema domain at amino acids 24-506. These domains are all located in the extracellular region (Uniprot Q80UG2). Homozygous null mice exhibit defective trajecotory and projection of peripheral sensory axons and sympathetic ganglion axons and the formation of the anterior commissure and the barrels.

The D1330V change is located in the cytoplasmic region, and is predicted to be probably damaging by the PolyPhen program.
