| Fetal anomalies v0.199 | COG4 | Rebecca Foulger commented on gene: COG4: The evidence for Saul-Wilson syndrome (MIM:618150) comes from one 2018 paper (PMID:30290151): Ferreira et al. (PMID:30290151, 2018) identified 2 different de novo heterozygous vaiants in the COG4 gene in 14 individuals, c.1546G-A and c.1546G-C both of which give rise to an identical missense mutation (G516R). Functional analysis shows that a stable protein is produced and, despite Golgi collapse, glycosylation is relatively normal. Given the DD-G2P Disease confidence rating is 'probable' (March 2019), only a missense variant has been reported, and functional evidence doesn't yet show the effect of the protein alteration, I have kept the MOI for COG4 on the Fetal anomalies panel as biallelic (for the confirmed glycosylation disorder) and not included the monoallelic Saul-Wilson syndrome on the panel at this stage. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Rebecca Foulger commented on gene: COG4: COG4 is Green on the fetal panel based on 'confirmed' rating for a biallelic glycosylation disorder (COG4-CDG) and expert clinical review. A probable gene:disease disorder also exists in DD-Gene2Phenotype: Saul-Wilson syndrome. DDG2P Disease confidence: probable. DDG2P mode of pathogenicity/mutation consequence: all missense/in frame, gain of function. DDG2P mode of inheritance: monoallelic. Saul-Wilson syndrome is a rare form of primordial dwarfism with severe pre-and postnatal growth retardation, and characteristic facial and radiographic features (PMID:30290151). Fetal relevance was confirmed by Anna de Burca but the evidence requires further investigation before the MOI is expanded to include monoallelic variants. |

| Fetal anomalies v0.134 | COG4 | Rebecca Foulger edited their review of gene: COG4: Added comment: This gene and phenotype were reviewed during meetings at Great Ormond Street hospital in March 2019. Clinical review and curation was performed by Lyn Chitty, Anna de Burca, Rhiannon Mellis, Richard Scott, Ellen McDonagh and Rebecca Foulger. Outcome of review: Confirmed that phenotype is fetally-relevant: keep on the Fetal anomalies panel as a Green gene.; Changed rating: GREEN | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
