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]
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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 18, 2022The c.1051G>A (p.A351T) alteration is located in exon 4 (coding exon 4) of the TMEM129 gene. This alteration results from a G to A substitution at nucleotide position 1051, causing the alanine (A) at amino acid position 351 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
