Zornitza Stark changed review comment from: Well established gene-disease association. Variable severity: for review. Affected individuals can manifest prolonged nasal and mucosal haemorrhage, menorrhagia, haematuria, and occasionally hemarthrosis. Treatment: plasma-derived factor 10 concentrate (Coagadex); to: Well established gene-disease association. Affected individuals can manifest prolonged nasal and mucosal haemorrhage, menorrhagia, haematuria, and occasionally hemarthrosis. Treatment: plasma-derived factor 10 concentrate (Coagadex) |

Lilian Downie gene: USP18 was added gene: USP18 was added to Baby Screen+ newborn screening. Sources: Expert list Mode of inheritance for gene: USP18 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: USP18 were set to PMID: 31940699, 27325888, 12833411 Phenotypes for gene: USP18 were set to Pseudo-TORCH syndrome 2 MIM#617397 Review for gene: USP18 was set to AMBER Added comment: antenatal onset of intracranial hemorrhage, calcification, brain malformations, liver dysfunction, and often thrombocytopenia. Affected individuals tend to have respiratory insufficiency and seizures, and die in infancy. The phenotype resembles the sequelae of intrauterine infection, but there is no evidence of an infectious agent. The disorder results from inappropriate activation of the interferon (IFN) immunologic pathway Treatment Ruxolitinib (single patient only) - is a single patient with successful treatment enough?

Sources: Expert list Mode of inheritance for gene: VKORC1 was set to BOTH monoallelic and biallelic, autosomal or pseudoautosomal Publications for gene: VKORC1 were set to PMID:14765194, PMID: 26287237 Phenotypes for gene: VKORC1 were set to Vitamin K-dependent clotting factors, combined deficiency of, 2 MIM#607473 Review for gene: VKORC1 was set to AMBER Added comment: Risk of intracranial haemmorhage in first weeks of life Treatable with vitamin K See below summary - feels like should be green for that homozygous mutation but not sure how to manage the gene overall? not report other variants? Monoallelic - warfarin resistance There is only one mutation known to result in the VKCFD2 phenotype. VKORC1:p.Arg98Trp causes diminished vitamin K epoxide reductase (VKOR) activity compared to that of the wild-type enzyme [15]. VKCFD2 patients exhibit severely diminished activities for the VKD coagulation factors and suffer spontaneous or surgery/injury induced bleeding episodes [16,17]. In addition to this haemorrhagic phenotype, abnormalities in epiphyseal growth have been reported in one case [18]. This phenotype is very rare. Worldwide, there are only four unrelated families known to be affected with VKCFD2 [16,17,18]. Sources: Expert list |

Zornitza Stark changed review comment from: Well established gene-disease association. Variable severity. Treatment: Recombinant coagulation Factor VIIa Non-genetic confirmatory testing: factor VII level; to: Well established gene-disease association. Variable severity. Treatment: Recombinant coagulation Factor VIIa Non-genetic confirmatory testing: factor VII level Rated as 'strong actionability' in paediatric patients by ClinGen. Clinical expression of factor VII deficiency is highly variable, and no consistent relationship has been found between the severity of the hemorrhagic syndrome and the residual levels of FVII activity. Individuals can be completely asymptomatic despite a very low FVII level. A bleeding history appears more predictive of further bleeding than the factor VII level. Factor VII levels increase during pregnancy, but levels usually remain insufficient for hemostasis in severely affected cases. Individuals with no history of bleeding do not appear to be at increased risk of PPH. Heterozygotes often have approximately half-normal levels of coagulation factors and are often asymptomatic. However, up to 2% of patients with severe bleeding phenotype are heterozygotes. Consider prophylaxis using rFVIIa in certain circumstances. Long term prophylaxis should be considered for cases with a personal or family history of severe bleeding or with FVII activity <0.01 IU/ml using rFVIIa, adjusting to maintain clinical response. Short term prophylaxis should be considered for cases for neonates without a personal or family history of severe bleeding but who have FVII activity 0.01-0.05 IU/ml up to 6-12 months of age. |

Zornitza Stark changed review comment from: Well established gene disease association. Clingen: strong actionability in adults Although HHT is a developmental disorder and infants are occasionally severely affected, in most people the features are age-dependent and the diagnosis is not suspected until adolescence or later. The average age of onset for epistaxis is 12 years, with 50-80% of patients affected before the age of 20 and 78-96% developing it eventually. Most patients report the appearance of telangiectasia of the mouth, face, or hands 5-30 years after the onset of nose bleeds, most commonly during the third decade. GI bleeding, when present, usually presents in the 5th or 6th decades of life. Patients rarely develop significant GI bleeding before 40 years of age. Women are affected with GI bleeding in a ratio of 2-3:1. AVMs of the brain are typically present at birth, whereas those in the lung and liver typically develop over time. Hemorrhage is often the presenting symptom of cerebral AVMs, while visceral AVMs may cause transient ischemic attacks, embolic stroke, and cerebral or other abscesses. Hepatic AVMs can present as high-output heart failure, portal hypertension, or biliary disease. However, screening guidelines recommend screening for cerebral AVMs in first 6 months of life or at diagnosis (MRI). For review.; to: Well established gene disease association.
