Genes affected
FARS2 (HGNC:21062): (phenylalanyl-tRNA synthetase 2, mitochondrial) This gene encodes a protein that transfers phenylalanine to its cognate tRNA. This protein localizes to the mitochondrion and plays a role in mitochondrial protein translation. Mutations in this gene can cause combined oxidative phosphorylation deficiency 14 (Alpers encephalopathy). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

Combined oxidative phosphorylation defect type 14 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jun 22, 2023 | For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with FARS2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Ser4*) in the FARS2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in FARS2 are known to be pathogenic (PMID: 22833457). - |
