Rebecca Foulger commented on gene: ALG8: As discussed with members of the GMS Neurology Specialist Test Group on the Webex call 22nd November 2019 for Clinical Indication R59 Early onset or syndromic epilepsy: Agreed that there is enough evidence to rate this gene Green. Although there is inconsistency amongst patients, there are sufficient cases for a Green rating. Kept rating as Green.
Rebecca Foulger changed review comment from: 26066342 (Hock et al., 2015) describe 3 new patients with ALG8-CDG, provide an update on 2 previous patients and summarise 10 previous patients.

Brain involvement (psychomotor disability or seizures or ataxia or structural anomalies) were seen in 12/13 patients.; to: 26066342 (Hock et al., 2015) describe 3 new patients with ALG8-CDG, provide an update on 2 previous patients and summarise 10 previous patients.

Rebecca Foulger commented on gene: ALG8: PMID:19688606 (Vesela et al., 2009) present a girl with neonatal onset of CDG. Seizures were present from the first day and the girl died age 2 months from progressive oedema, bleeding and cardio-respiratory insufficiency. She had compound het variants in ALG8 (p.T47P and p.R364X).
Rebecca Foulger commented on gene: ALG8: PMID:23430830 (Millon et al., 2011) report 2 siblings with a congenital glycosylation disorder. Their clinical presentation included seizures. The authors could not identify the genetic deficiency in these patients yet.

Tracy Lester reviewed gene: ALG8: Rating: GREEN; Mode of pathogenicity: ; Publications: ; Phenotypes: Congenital disorder of glycosylation, type Ih 608104, Polycystic liver disease 3 with or without kidney cysts 617874; Mode of inheritance: BIALLELIC, autosomal or pseudoautosomal
Sarah Leigh commented on gene: ALG8: Associated with Congenital disorder of glycosylation, type Ih 608104 in OMIM and as confirmed Gen2Phen, however, neither resource recorded seizures among the phenotypic features. Variants have been reported in at least 13 cases carrying biallelic ALG8 variants PMIDs 26066342 & 19688606.
