Early onset or syndromic epilepsy v2.491 ALG14 Sarah Leigh Tag for-review was removed from gene: ALG14.
Early onset or syndromic epilepsy v2.491 ALG14 Sarah Leigh commented on gene: ALG14: The rating of this gene has been updated following NHS Genomic Medicine Service approval.
Early onset or syndromic epilepsy v2.490 ALG14 Sarah Leigh Source Expert Review Green was added to ALG14.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Early onset or syndromic epilepsy v2.287 ALG14 Sarah Leigh commented on gene: ALG14: For-review tag has been added to highlight whether this gene should be green on this panel due to the uncoupling of metabolic genes from Genetic epilepsy syndromes panel.
Early onset or syndromic epilepsy v2.277 ALG14 Sarah Leigh edited their review of gene: ALG14: Changed rating: GREEN
Early onset or syndromic epilepsy v2.274 ALG14 Helen Lord reviewed gene: ALG14: Rating: GREEN; Mode of pathogenicity: None; Publications: 28733338, 30221345; Phenotypes: epilepsy, behavioural problems, severe developmental delay, mild dysmorphic features, severe neurodegeneration with myopathic and myasthenic features; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Early onset or syndromic epilepsy v2.115 ALG14 Sarah Leigh changed review comment from: Associated with Myasthenic syndrome, congenital, 15, without tubular aggregates 616227 in OMIM, but not associated with phenotype in Gen2Phen. At least 6 variants reported in at least 5 cases with varying phenotypes. PMID 23404334 reports compound heterozygous (p.P65L, P.R104*) sibs, who manifested with myasthenic syndromes, but did not have intellectural disability nor seizures and were 62 and 51 years old when reported. PMID 28733338 reports two compound heterozygous (p.D74N, pV141G), (p.D74N, p.R109Q) cases and a homozygous ((p.D74N), with early and lethal neurodegeneration with myasthenic and myopathic features, but the cases died before intellectual disability was manifiest. However, seizures were evident in two compound heterozygous families. PMID 30221345 reports a homozygous splicing variant in a case with intellectual disability and seizures. Functional studies were presented showing that this variant resulting in exon skipping, however, this was not completely prenetrant as wild type protein was detected at a low level in the patient.
