| Glutaminase deficiency is inherited via an autosomal recessive manner | |
| Causes | Mutation in GLS gene |
Glutaminase deficiency is a rare genetic disorder that presents in childhood.[1] It is associated with epilepsy and usually results in an early demise.
This condition is characterised by refractory seizures, respiratory failure, brain abnormalities and death in the neonatal period.
This condition is caused by mutations in the glutaminase (GLS) gene. The inheritance of this condition is autosomal recessive. Milder cases have been reported due a mutation in the 5' region of the gene.[2]
This diagnosis is made by sequencing the GLS gene. There is presently no curative treatment. Management is supportive.
The prevalence is not known but this is considered to be a rare disease. As of 2019 only seven cases have been reported.
This condition was first described in 2018.[1]
