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 as homozygotes in two unrelated cases, together with segregation and supportive functional studies.

gene: DPM3 review by Ellen McDonagh

Probable DD gene for CONGENITAL DISORDER OF GLYCOSYLATION TYPE 1O. One patient reported in PMID:19576565, and a zebrafish and yeast models have been reported (PMID: 27291147, 21521073). Both DPM1 and DPM2 with DPM3 form the Dolichol-phosphate mannose (DPM) synthase enzyme (PMID:10835346), and these two genes are green on this panel as more patient cases have been reported for variants within this gene. DPM2 stabilizes DPM3 and DPM3 stabilizes DPM1 (PMID:10835346). A DPM1 variant in an infant with the phenotype of a congenital muscular dystrophy was reported to affect binding to DPM3 (PMID: 23856421). In vitro data suggests without DPM3, DPM1 is rapidly degraded (PMID: 16280320). Watchlist tag added as further information about association between DPM3 and the other genes could result in promotion to green.
