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.

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

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 18, 2021The c.973G>A (p.G325S) alteration is located in exon 10 (coding exon 10) of the GLS2 gene. This alteration results from a G to A substitution at nucleotide position 973, causing the glycine (G) at amino acid position 325 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
