TPGS2 (HGNC:24561): (tubulin polyglutamylase complex subunit 2) This gene encodes a protein that is a component of the neuronal polyglutamylase complex, which plays a role in post-translational addition of glutamate residues to C-terminal tubulin tails. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2012]

The c.14C>T (p.A5V) alteration is located in exon 1 (coding exon 1) of the KIAA1328 gene. This alteration results from a C to T substitution at nucleotide position 14, causing the alanine (A) at amino acid position 5 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
