Genes affected

DPYSL2 (HGNC:3014): (dihydropyrimidinase like 2) This gene encodes a member of the collapsin response mediator protein family. Collapsin response mediator proteins form homo- and hetero-tetramers and facilitate neuron guidance, growth and polarity. The encoded protein promotes microtubule assembly and is required for Sema3A-mediated growth cone collapse, and also plays a role in synaptic signaling through interactions with calcium channels. This gene has been implicated in multiple neurological disorders, and hyperphosphorylation of the encoded protein may play a key role in the development of Alzheimer's disease. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Sep 2011]

The c.995G>A (p.R332Q) alteration is located in exon 7 (coding exon 7) of the DPYSL2 gene. This alteration results from a G to A substitution at nucleotide position 995, causing the arginine (R) at amino acid position 332 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
