Sarah Leigh (Genomics England Curator)

Comment on list classification: This gene was part of an initial gene list collated by Emma Ashton on behalf of the London North GLH, for GMS Metabolic Consensus Specialist Test Group. Additional information was not provided, such as mode of inheritance and phenotype.
Associated with relevant phenotype in OMIM and as probable Gen2Phen gene. At least 2 variants reported, one of which (c.320A>G, p.N107S) is associated with Epileptic encephalopathy, early infantile, 36 300884 as a de novo variant in at least 6 unrelated cases, athough the conection with Congenital disorder of glycosylation, type Is 300884 is not clear from these cases. The second variant was reported in an infant who died at age 1 year. Transferrin isoelectric focusing showed abnormal N-glycosylation and was consistent with a diagnostic classification of congenital disorder of glycosylation type Is (CDG1S). Studies of patient-derived cells showed decreased enzyme activity, at about 17% of wildtype (PMID 22492991).
