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]

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 14, 2023The c.430C>G (p.Q144E) alteration is located in exon 3 (coding exon 3) of the TXLNG gene. This alteration results from a C to G substitution at nucleotide position 430, causing the glutamine (Q) at amino acid position 144 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
