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

Verdict is Likely_benign. Variant got -4 ACMG points.

• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0000132 (2/151694) while in subpopulation SAS AF= 0.000415 (2/4820). AF 95% confidence interval is 0.000073. There are 0 homozygotes in gnomad4. There are 1 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck.
