| Adult onset leukodystrophy v1.25 | EPRS | Eleanor Williams Added comment: Comment on list classification: Promoting from grey to amber but with recommendation for green rating following GMS review. 4 unrelated cases. Presentation generally before age of 18 but after consultation with the Genomics England clinical team it was decided that it was also appropriate to propose as green on the adult onset panel. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Eleanor Williams edited their review of gene: EPRS: Added comment: As reported by the expert reviewer PMID: 29576217 (Mendes et al 2018) reports 4 unrelated affected individuals with hypomyelination and biallelic (homozygous or compound het) pathogenic variants in EPRS. 5 variants in total identified (1 nonsense, 1 frameshift, 3 missense). Variants segregated with the disease in all 4 families. All 4 presented initially before the age of 18 and in all brain MRI showed a hypomyelinating leukodystrophy with thinning of the corpus callosum. In 3 cases the variant was identified by WES, in one by direct sequencing of EPRS1. PMID: 33805425 - Sawaguchi et al 2021 - using a mouse model they show that EPRS1 variant Arg339-to-Ter (R339X) (found in one of the patients in Mendes et al in heterozgyous state with another variant) localizes EPRS1 proteins as polymeric aggregates into Rab7-positive vesicle structures in mouse oligodendroglial FBD-102b cells. Wild-type proteins are distributed throughout the cell bodies. This seems to inhibit cell morphological differentiation.; Changed rating: GREEN; Changed publications to: 29576217, 33805425; Changed phenotypes to: Leukodystrophy, hypomyelinating, 15, OMIM:617951; Changed mode of inheritance: BIALLELIC, autosomal or pseudoautosomal |

Sources: Expert list Mode of inheritance for gene: EPRS was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: EPRS were set to 29576217 Phenotypes for gene: EPRS were set to Leukodystrophy, hypomyelinating, 15, MIM# 617951 Review for gene: EPRS was set to GREEN gene: EPRS was marked as current diagnostic Added comment: Four unrelated families reported with this neurodegenerative disorder. Onset of motor and cognitive impairment in the first or second decade of life. Features include dystonia, ataxia, spasticity, dysphagia, severe optic atrophy, and some have hearing loss. Brain imaging shows hypomyelinating leukodystrophy with thin corpus callosum. Sources: Expert list |
