Genes affected

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]

Ambry Genetics

Dec 01, 2022

The c.434T>C (p.F145S) alteration is located in exon 5 (coding exon 5) of the TPGS2 gene. This alteration results from a T to C substitution at nucleotide position 434, causing the phenylalanine (F) at amino acid position 145 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
