Genes affected

SPRYD4 (HGNC:27468): (SPRY domain containing 4) Located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

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.
