Likely inborn error of metabolism - targeted testing not possible
Gene: DHDDSComment 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 for Retinitis pigmentosa 59 613861. One variant was reported in at least 15 families with retinitis pigmentosa, but only one compound individual with glycosylation defects was identifed so far (PMID 27343064).Created: 13 Aug 2019, 1:17 p.m. | Last Modified: 13 Aug 2019, 1:17 p.m.
