Genes affected

TXLNG (HGNC:18578): (taxilin gamma) This gene encodes a member of the taxilin family. The encoded protein binds to the C-terminal coiled-coil region of syntaxin family members 1A, 3A and 4A, and may play a role in intracellular vesicle trafficking. This gene is up-regulated by lipopolysaccharide and the gene product may be involved in cell cycle regulation. The related mouse protein was also shown to inhibit activating transcription factor 4-mediated transcription and thus regulate bone mass accrual. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2009]

Collection Method:clinical testing

The c.13G>T (p.V5L) alteration is located in exon 1 (coding exon 1) of the TXLNG gene. This alteration results from a G to T substitution at nucleotide position 13, causing the valine (V) at amino acid position 5 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
