Genes affected

LDHAL6A (HGNC:28335): (lactate dehydrogenase A like 6A) Predicted to enable L-lactate dehydrogenase activity. Predicted to be involved in carbohydrate metabolic process and carboxylic acid metabolic process. Located in extracellular exosome. [provided by Alliance of Genome Resources, Apr 2022]

LDHAL6A links:

TSG101 (HGNC:15971): (tumor susceptibility 101) The protein encoded by this gene belongs to a group of apparently inactive homologs of ubiquitin-conjugating enzymes. The gene product contains a coiled-coil domain that interacts with stathmin, a cytosolic phosphoprotein implicated in tumorigenesis. The protein may play a role in cell growth and differentiation and act as a negative growth regulator. In vitro steady-state expression of this tumor susceptibility gene appears to be important for maintenance of genomic stability and cell cycle regulation. Mutations and alternative splicing in this gene occur in high frequency in breast cancer and suggest that defects occur during breast cancer tumorigenesis and/or progression.

Collection Method: clinical testing

The c.610G>A (p.V204M) alteration is located in exon 5 (coding exon 5) of the LDHAL6A gene. This alteration results from a G to A substitution at nucleotide position 610, causing the valine (V) at amino acid position 204 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
