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 GeneticsJun 02, 2023The c.1411C>T (p.R471W) alteration is located in exon 14 (coding exon 14) of the GLS2 gene. This alteration results from a C to T substitution at nucleotide position 1411, causing the arginine (R) at amino acid position 471 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
