Genes affected

GLS (HGNC:4331): (glutaminase) This gene encodes the K-type mitochondrial glutaminase. The encoded protein is an phosphate-activated amidohydrolase that catalyzes the hydrolysis of glutamine to glutamate and ammonia. This protein is primarily expressed in the brain and kidney plays an essential role in generating energy for metabolism, synthesizing the brain neurotransmitter glutamate and maintaining acid-base balance in the kidney. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jan 2012]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.00593856).

BS1

Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0000131 (2/152092) while in subpopulation AMR AF= 0.000131 (2/15286). AF 95% confidence interval is 0.0000226. There are 0 homozygotes in gnomad4. There are 1 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.36C>A (p.D12E) alteration is located in exon 1 (coding exon 1) of the GLS gene. This alteration results from a C to A substitution at nucleotide position 36, causing the aspartic acid (D) at amino acid position 12 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
