Genes affected

TMEM129 (HGNC:25137): (transmembrane protein 129, E3 ubiquitin ligase) Enables ubiquitin protein ligase activity. Involved in protein polyubiquitination; retrograde protein transport, ER to cytosol; and ubiquitin-dependent ERAD pathway. Located in endoplasmic reticulum. [provided by Alliance of Genome Resources, Apr 2022]

TMEM129 links:

TACC3 (HGNC:11524): (transforming acidic coiled-coil containing protein 3) This gene encodes a member of the transforming acidic colied-coil protein family. The encoded protein is a motor spindle protein that may play a role in stabilization of the mitotic spindle. This protein may also play a role in growth a differentiation of certain cancer cells.

Ambry Genetics

Jul 30, 2024

The c.608C>T (p.S203L) alteration is located in exon 2 (coding exon 2) of the TMEM129 gene. This alteration results from a C to T substitution at nucleotide position 608, causing the serine (S) at amino acid position 203 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
