Genes affected

GLS2 (HGNC:29570): (glutaminase 2) The protein encoded by this gene is a mitochondrial phosphate-activated glutaminase that catalyzes the hydrolysis of glutamine to stoichiometric amounts of glutamate and ammonia. Originally thought to be liver-specific, this protein has been found in other tissues as well. Alternative splicing results in multiple transcript variants that encode different isoforms.

Dec 17, 2021

The c.200G>A (p.G67D) alteration is located in exon 2 (coding exon 2) of the GLS2 gene. This alteration results from a G to A substitution at nucleotide position 200, causing the glycine (G) at amino acid position 67 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
