Zornitza Stark changed review comment from: Assessed as 'moderate actionability' in paediatric patients by ClinGen. In classic FD, the first symptoms, including chronic neuropathic pain and episodic severe pain crises, emerge during childhood (typically age 3-10 years). Heterozygous females typically have a later median age of onset than males (9-13 years versus 13-23 years). Rarely, females may be relatively asymptomatic and have a normal life span or may have symptoms as severe as males with the classic phenotype. Cardiac and/or cerebrovascular disease is present in most males by middle age while ESRD usually develops during the third to fifth decade. Renal and cardiac failure represent major sources of morbidity, and account for the reduced lifespan among affected males (50-58 years) and females (70-75 years) compared to the normal population. A systematic review of RCTs of ERT reported on nine studies of 351 FD patients; however, many of these studies reported only on the effect of ERT on levels of enzyme substrate. Data from 2 trials (n=39 males) found no statistically significant differences in plasma enzyme substrate and one trial (n=24 males) found no statistical differences in renal function between individuals treated with agalsidase alfa and placebo (up to 6-month follow-up). Similar results were seen for agalsidase beta. One trial of 26 male patients found a statistically significant difference in pain, favoring agalsidase alfa compared to placebo at 5-6 months after treatment. No trial reported on the effect of agalsidase alfa on mortality or cardiac/cerebrovascular disease. One trial of agalsidase beta (n=82 males and females) found no difference in mortality, renal function, or symptoms or complications of cardiac or cerebrovascular disease over 18 months. The long-term influence of ERT on risk of morbidity and mortality related to FD remains to be established. Migalastat, an oral chaperone drug, is recommended as an option for treatment for some patients with FD who are over 16 years with an amenable genetic variant who would usually be offered ERT. For non-amenable genotypes, migalastat may result in a net loss of alpha-Gal A activity, potentially worsening the disease condition. A systematic review evaluated 2 phase III RCTs that both included males and females. One RCT randomized patients to switch from ERT to migalastat (n = 36) or continue with ERT (n = 24) during an 18-month period with a 12-month extension in which all patients received migalastat. During the treatment period, the percentage of patients who had a renal, cardiac, or cerebrovascular event or died was 29% of patients on migalastat compared to 44% of patients on ERT. However, this difference was not statistically significant. A second RCT compared migalastat (n=34) with placebo (n=33) over a 6-month period, with an 18-month extension study. The primary outcome was change from baseline in interstitial capillary inclusions of the enzyme substrate globotriaosylceramide (GL-3), which was not significantly different between groups. Results from both trials indicate that migalastat does not have a significant beneficial effect on pain, health-related quality of life outcomes, or glomerular filtration rate (results were uncertain due to large confidence intervals, small sample sizes, and/or short follow-up time). Migalastat did not influence left ventricular ejection fraction but did improve left ventricular mass over 18 months. There are a number of recommendations for surveillance and agents to avoid (amiodarone).

Zornitza Stark gene: ITGB3 was added gene: ITGB3 was added to gNBS. Sources: ClinGen treatable, haematological tags were added to gene: ITGB3. Mode of inheritance for gene: ITGB3 was set to BIALLELIC, autosomal or pseudoautosomal Phenotypes for gene: ITGB3 were set to Glanzmann thrombasthenia 2, MIM# 619267 Review for gene: ITGB3 was set to GREEN Added comment: Rated as 'strong actionability' in paediatric patients by ClinGen. GT can present soon after birth with episodic mucocutaneous bleeding, purpura, petechiae, unprovoked bruising, and excessive bleeding from the umbilical stump or post-circumcision. Major bleeding complications during the neonatal period, such as ICH following delivery are rare. The clinical severity of GT tends to diminish with age, although the bleeding manifestations persist and are life-long. Recombinant activated factor VII (rFVIIa) may be considered for patients with: moderate to severe acute bleeding; for treatment of refractory minor bleeds; for prophylaxis in patients with frequent severe bleeds; treatment during minor and major surgery; and in patients who are refractory to platelet transfusion. Some guidelines suggest utilizing rFVIIa as a first line therapy and saving platelet transfusion for more severe or non-responsive bleeds. High doses have been successful, particularly if used early and upfront. rFVIIa in a dose of =80 µg/kg at intervals of 2.5 h or less were observed to be safe and effective in nonsurgical bleeds, minor and major procedures in patients with or without antibodies, and/or refractoriness. The International Glanzmann Thrombasthenia Registry (GTR), published in 2015, studied 184 patients with 829 bleeding episodes and 96 patients with 206 surgical interventions. rFVIIa alone was used in 124/829 bleeds and the proportion of successful treatment to stop bleeding was 91%. In patients without antibodies/refractoriness, rFVIIa, either alone or with antifibrinolytics, and platelets±antifibrinolytics were rated 100% effective for 24 minor and 4 major procedures. The lowest effectiveness of rFVIIa treatment alone was 88.9% (16/18 effective minor procedures) in refractory patients with platelet antibodies. Desmopressin (DDAVP) may be considered as an additional treatment for mild bleeding episodes. DDAVP has been shown to be effective in many bleeding disorders, including inherited platelet function disorders. However, DDAVP efficacy among GT patients has not been established and guideline recommendations are conflicting. Sources: ClinGen |
