Post-procedure sedation and apnea linked to ion channel variant: a case report on dexmedetomidine-propofol interaction Gabriele Stocco, Anna Galletti, Marianna Lucafò, Nagua Giurici, Debora Curci, Sara Solidoro, Valentina Kiren, Anna Monica Bianco, Egidio Barbi, Pio D’Adamo Frontiers in Pharmacology, 2025 We report a case of post-awakening recurrent episodes of spontaneous re-sedation and apnea with severe desaturation after procedural sedation with dexmedetomidine and propofol in a leukemic adolescent with an ionic channel variant. The mutation is located in the 3′-UTR regulatory region of SCN9A. We speculate that this variant may affect the stability of the mRNA, making the patient more susceptible to the combined effects of propofol and dexmedetomidine. This is the first pediatric report of late onset re-sedation with apnoea after combined sedation with propofol and dexmedetomidine highlighting the risk of adverse events in selected patients with a genetic increased susceptibility. If validated by further studies, pharmacogenetic testing may be implemented to provide personalized therapies in patients needing anesthesia.
Sensitive Detection of Gynecological Cancer Recurrence Using Circulating Tumor DNA and Digital PCR: A Comparative Study with Serum Biochemical Markers Nour Balasan, Feras Kharrat, Giovanni Di Lorenzo, Emmanouil Athanasakis, Anna Monica Bianco, Andrea Conti, Maria Teresa Di Stazio, Giulia Butera, Stefania Cicogna, Alessandro Mangogna, Federico Romano, Giuseppe Ricci, Adamo Pio d’Adamo International Journal of Molecular Sciences, 2024 Early detection of recurrences in gynecological cancers is crucial for women’s health. Circulating tumor DNA (ctDNA) analysis through liquid biopsy offers a promising approach for monitoring disease progression and identifying relapses. This study investigated the utility of digital Polymerase Chain Reaction (dPCR) for ctDNA detection in three gynecological cancer patients with clinically confirmed relapses during a two-year post-surgical follow-up. Patient-specific tumor mutations were identified through whole-exome sequencing (WES) and confirmed via Sanger sequencing. dPCR probes targeting these mutations were used to quantify the ctDNA levels in plasma samples collected throughout the follow-up period, and the findings were compared with standard serum biochemical markers. In two patients, persistent positive dPCR signals for the selected mutations were detected after tumor removal, with ctDNA levels progressively increasing even after post-surgical chemotherapy. Notably, dPCR identified elevated ctDNA levels before an increase in the cancer antigen 125 (CA125) biochemical marker was observed. In the third patient, no ctDNA signals from the two selected mutations were detected despite clinical evidence of recurrence, suggesting the emergence of new mutations. While this study highlights the promise of dPCR for early recurrence detection in gynecological cancers, it also underscores the critical need for comprehensive mutation panels to overcome the inherent challenges posed by tumor heterogeneity and the emergence of new mutations during disease progression.
Genetic bases of C7 deficiency: systematic review and report of a novel deletion determining functional hemizygosity Andrea Balduit, Anna Monica Bianco, Alessandro Mangogna, Anna Maria Zicari, Lucia Leonardi, Bianca Laura Cinicola, Martina Capponi, Alberto Tommasini, Chiara Agostinis, Adamo Pio d’Adamo, Roberta Bulla Frontiers in Immunology, 2023 Primary complement system (C) deficiencies are rare but notably associated with an increased risk of infections, autoimmunity, or immune disorders. Patients with terminal pathway C-deficiency have a 1,000- to 10,000-fold-higher risk of Neisseria meningitidis infections and should be therefore promptly identified to minimize the likelihood of further infections and to favor vaccination. In this paper, we performed a systematic review about clinical and genetic patterns of C7 deficiency starting from the case of a ten-year old boy infected by Neisseria meningitidis B and with clinical presentation suggestive of reduced C activity. Functional assay via Wieslab ELISA Kit confirmed a reduction in total C activity of the classical (0.6% activity), lectin (0.2% activity) and alternative (0.1% activity) pathways. Western blot analysis revealed the absence of C7 in patient serum. Sanger sequencing of genomic DNA extracted from peripheral blood of the patient allowed the identification of two pathogenetic variants in the C7 gene: the already well-characterized missense mutation G379R and a novel heterozygous deletion of three nucleotides located at the 3’UTR (c.*99_*101delTCT). This mutation resulted in an instability of the mRNA; thus, only the allele containing the missense mutation was expressed, making the proband a functional hemizygote for the expression of the mutated C7 allele.
What Is the Exact Contribution of PITX1 and TBX4 Genes in Clubfoot Development? An Italian Study Anna Monica Bianco, Giulia Ragusa, Valentina Di Carlo, Flavio Faletra, Mariateresa Di Stazio, Costantina Racano, Giovanni Trisolino, Stefania Cappellani, Maurizio De Pellegrin, Ignazio d’Addetta, Giuseppe Carluccio, Sergio Monforte, Antonio Andreacchio, Daniela Dibello, Adamo P. d’Adamo Genes, 2022 Congenital clubfoot is a common pediatric malformation that affects approximately 0.1% of all births. 80% of the cases appear isolated, while 20% can be secondary or associated with complex syndromes. To date, two genes that appear to play an important role are PTIX1 and TBX4, but their actual impact is still unclear. Our study aimed to evaluate the prevalence of pathogenic variants in PITX1 and TBX4 in Italian patients with idiopathic clubfoot. PITX1 and TBX4 genes were analyzed by sequence and SNP array in 162 patients. We detected only four nucleotide variants in TBX4, predicted to be benign or likely benign. CNV analysis did not reveal duplications or deletions involving both genes and intragenic structural variants. Our data proved that the idiopathic form of congenital clubfoot was rarely associated with mutations and CNVs on PITX1 and TBX4. Although in some patients, the disease was caused by mutations in both genes; they were responsible for only a tiny minority of cases, at least in the Italian population. It was not excluded that other genes belonging to the same TBX4-PITX1 axis were involved, even if genetic complexity at the origin of clubfoot required the involvement of other factors.
MYO5B Gene Mutations: A Not Negligible Cause of Intrahepatic Cholestasis of Infancy with Normal Gamma-Glutamyl Transferase Phenotype Lorenza Matarazzo, Anna Monica Bianco, Emmanouil Athanasakis, Marco Serveres, Paola Francalanci, Giovanna Cenacchi, Giuseppe Maggiore, Adamo Pio D'Adamo Journal of Pediatric Gastroenterology and Nutrition, 2022 Objectives:Progressive familial intrahepatic cholestasis is an expanding group of autosomal recessive intrahepatic cholestatic disorders. Recently, next‐generation sequencing allowed identifying new genes responsible for new specific disorders. Two biochemical phenotypes have been identified according to gamma‐glutamyltransferase (GGT) activity. Mutations of the myosin 5B gene (MYO5B) are known to cause microvillus inclusion disease. Recently, different mutations in MYO5B gene have been reported in patients with low‐GGT cholestasis.Methods:A multicenter retrospective and prospective study was conducted in 32 children with cryptogenic intrahepatic cholestasis. Clinical, biochemical, histological, and treatment data were analyzed in these patients. DNA from peripheral blood was extracted, and all patients were studied by whole exome sequencing followed by Sanger sequencing.Results:Six patients out of 32 had mutations in the MYO5B gene. Of these six patients, the median age at disease onset was 0.8 years, and the median length of follow‐up was 4.2 years. The most common signs were pruritus, poor growth, hepatomegaly, jaundice, and hypocholic stools. Two patients also showed intestinal involvement. Transaminases and conjugated bilirubin were moderately increased, serum bile acids elevated, and GGT persistently normal. At anti‐Myo5B immunostaining, performed in liver biopsy of two patients, coarse granules were evident within the cytoplasm of hepatocytes while bile salt export pump was normally expressed at the canalicular membrane. Six variants in homozygosity or compound heterozygosity in the MYO5B gene were identified, and three of them have never been described before. All nucleotide alterations were located on the myosin motor domain except one missense variant found in the isoleucine‐glutamine calmodulin‐binding motif.Conclusions:We identified causative mutations in MYO5B in 18.7% of a selected cohort of patients with intrahepatic cholestasis confirming a relevant role for the MYO5B gene in low‐GGT cholestasis.
The Genetic Diagnosis of Ultrarare DEEs: An Ongoing Challenge Luciana Musante, Paola Costa, Caterina Zanus, Flavio Faletra, Flora M. Murru, Anna M. Bianco, Martina La Bianca, Giulia Ragusa, Emmanouil Athanasakis, Adamo P. d’Adamo, Marco Carrozzi, Paolo Gasparini Genes, 2022 Epileptic encephalopathies (EEs) and developmental and epileptic encephalopathies (DEEs) are a group of severe early-onset neurodevelopmental disorders (NDDs). In recent years, next-generation equencing (NGS) technologies enabled the discovery of numerous genes involved in these conditions. However, more than 50% of patients remained undiagnosed. A major obstacle lies in the high degree of genetic heterogeneity and the wide phenotypic variability that has characterized these disorders. Interpreting a large amount of NGS data is also a crucial challenge. This study describes a dynamic diagnostic procedure used to investigate 17 patients with DEE or EE with previous negative or inconclusive genetic testing by whole-exome sequencing (WES), leading to a definite diagnosis in about 59% of participants. Biallelic mutations caused most of the diagnosed cases (50%), and a pathogenic somatic mutation resulted in 10% of the subjects. The high diagnostic yield reached highlights the relevance of the scientific approach, the importance of the reverse phenotyping strategy, and the involvement of a dedicated multidisciplinary team. The study emphasizes the role of recessive and somatic variants, new genetic mechanisms, and the complexity of genotype–phenotype associations. In older patients, WES results could end invasive diagnostic procedures and allow a more accurate transition. Finally, an early pursued diagnosis is essential for comprehensive care of patients, precision approach, knowledge of prognosis, patient and family planning, and quality of life.

Could the MED13 mutations manifest as a Kabuki-like syndrome? Laura De Nardi, Flavio Faletra, Adamo Pio D'Adamo, Anna Monica Rosaria Bianco, Emmanouil Athanasakis, Irene Bruno, Egidio Barbi American Journal of Medical Genetics Part A, 2021 MED13‐related disorder is a new neurodevelopmental disorder recently described in literature, which belongs to the group of CDK8‐kinase module genes‐associated conditions. It is characterized by variable intellectual disability and/or developmental delays, especially in language. Autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), eye or vision problems, hypotonia, mild congenital hearth abnormalities and dysmorphisms have been described among individuals with MED13 mutations. We report the case of a 13‐year‐old girl who received a previous clinical diagnosis of Kabuki syndrome (KS) without mutations in classic KS genes. After a whole exome sequencing (WES) analysis a de novo missense mutation in MED13 (c.C979T; p.Pro327Ser) was found. This variant has been once described in literature as accountable for a novel neurodevelopmental disorder. The aim of this report is to improve clinical delineation of MED13‐related condition and to explore differences and similarities between KS spectrum and MED13‐related disorders.
Notch signaling regulation in autoinflammatory diseases Rossella Gratton, Paola Maura Tricarico, Adamo Pio d'Adamo, Anna Monica Bianco, Ronald Moura, Almerinda Agrelli, Lucas Brandão, Luisa Zupin, Sergio Crovella International Journal of Molecular Sciences, 2020 Notch pathway is a highly conserved intracellular signaling route that modulates a vast variety of cellular processes including proliferation, differentiation, migration, cell fate and death. Recently, the presence of a strict crosstalk between Notch signaling and inflammation has been described, although the precise molecular mechanisms underlying this interplay have not yet been fully unravelled. Disruptions in Notch cascade, due both to direct mutations and/or to an altered regulation in the core components of Notch signaling, might lead to hypo- or hyperactivation of Notch target genes and signaling molecules, ultimately contributing to the onset of autoinflammatory diseases. To date, alterations in Notch signaling have been reported as associated with three autoinflammatory disorders, therefore, suggesting a possible role of Notch in the pathogenesis of the following diseases: hidradenitis suppurativa (HS), Behçet disease (BD), and giant cell arteritis (GCA). In this review, we aim at better characterizing the interplay between Notch and autoinflammatory diseases, trying to identify the role of this signaling route in the context of these disorders.
High prevalence of rare FBLIM1 gene variants in an Italian cohort of patients with Chronic Non-bacterial Osteomyelitis (CNO) Adamo Pio d’Adamo, Anna Monica Bianco, Giovanna Ferrara, Martina La Bianca, Antonella Insalaco, Alberto Tommasini, Manuela Pardeo, Marco Cattalini, Francesco La Torre, Martina Finetti, Clotilde Alizzi, Gabriele Simonini, Virginia Messia, Serena Pastore, Rolando Cimaz, Marco Gattorno, Andrea Taddio, and Pediatric Rheumatology, 2020 Background FBLIM1 gene has been recently demonstrated to be involved in the pathogenesis of bone sterile inflammation. The aim of the study is to evaluate the prevalence of FBLIM1 gene variants in a cohort of 80 Italian patients with Chronic Non-bacterial Osteomyelitis (CNO). Methods The coding regions of FBLIM1 gene were sequenced in a cohort of 80 patients with CNO using DNA extracted from blood lymphocytes, and PCR products were sequenced. Only rare (global MAF < 2%), coding variants detected were considered. Clinical evaluation of patients with rare variants and those without was performed. Fisher’s exact test was used to compare categorical and ordinal data, and Student’s t-test was used to analyze continuous data. Results Eighteen out of 80 patients (~ 22%) presented at least one rare coding variant in FBLIM1. Eight patients presented a variant never associated before with CNO. All patients presented classical features of CNO and no statistical difference between patients with presence of FBLMI1 variants and those without were found in terms of clinical manifestation, treatment, and outcome. Conclusion Considering the high frequency of rare variants in our CNO cohort, our data seem to confirm a possible role of FBLIM1 in the pathogenesis of CNO suggesting that CNO is a disorder of chronic inflammation and imbalanced bone remodeling.
