Serum Immunoglobulin G (IgG) Subclasses in a Cohort of Systemic Sclerosis Patients.

Objectives: To assess serum immunoglobulin G (IgG) subclasses in a cohort of systemic sclerosis (SSc) patients and to evaluate the influence of IgG subclasses in the main complications of the disease.

Methods: The serum level of IgG subclasses was evaluated in 67 SSc patients and 48 healthy controls (HC), matched for sex and age. Serum samples were collected and measured IgG1-4 subclasses by turbidimetry.

Duplex high resolution melting analysis (dHRMA) to detect two hot spot CYP24A1 pathogenic variants (PVs) associated to idiopathic infantile hypercalcemia (IIH).

Pathogenic variants (PVs) in CYP24A1 gene are associated with Idiopathic Infantile Hypercalcemia disease (IIH). The identification of CYP24A1 PVs can be a useful tool for the improvement of target therapeutic strategies. Aim of this study is to set up a rapid and inexpensive High Resolution Melting Analysis (HRMA)-based method for the simultaneous genotyping of two hot spot PVs in CYP24A1 gene, involved in IIH.

Identification and in silico characterization of a novel PKLR genotype in a Turkish newborn.

Pyruvate kinase deficiency (PKD) is the most common glycolytic defect leading to chronic nonspherocytic hemolytic anemia (CNSHA). Clinical manifestations of PKD reflect the symptoms and complications of the chronic hemolysis, including anemia, jaundice, bilirubin gallstones due to hyperbilirubinemia, splenomegaly and iron overload. In this study, we report the finding of a 5-months-old Turkish male newborn with moderate CNSHA and PKD.

High resolution melting profiles (HRMPs) obtained by magnetic induction cycler (MIC) have been used to monitor the BRCA2 status highlighted by next generation tumor sequencing (NGTS): a combined approach in a diagnostic environment.

Resistance can be the result of secondary tissue variants (STVs), which restore the open reading frame of the germline BRCA allele, producing functional BRCA protein in germline BRCA1/2 (BRCA) pathogenic variant (PV) carriers, treated with platinum-based chemotherapy or poly-(ADP-ribose) polymerase inhibitors (PARP-1). We reported recently a BRCA2 mutant high grade serous ovarian cancer (HGSOC) patient with acquired resistance to the PARP-1 olaparib due to a STV detected by next generation tumor sequencing (NGTS). The aim of this study was to evaluate the versatility of the high-resolution melting analysis (HRMA) obtained by magnetic induction cycler (MIC) to monitor the BRCA2 status in formalin-fixed paraffin-embedded (FFPE) tissue samples of this patient and to compare the results obtained by NGTS.

Identification of two novel LDLR variants by Next Generation Sequencing.

Introduction: Familial hypercholesterolemia (FH) is an autosomal dominant inherited disease characterized by elevated plasma low-density lipoprotein cholesterol (LDL-C). Targeted Next Generation Sequencing (NGS) is a new opportunity to expand the existing pathogenic variants (PVs) spectrum associated to FH. Our aim was to report a diagnostic NGS-based approach to detect variants associated to FH.

Spliceogenic analysis of BRCA1 c.439T>C (rs794727800) variant by High Resolution Melting Analysis.

Correct classification of genomic variants causing potentially aberrant splicing is of utmost importance for patient management, especially in clinically actionable genes such as BRCA1/2. In this article, we report molecular evaluation of the BRCA1 c.439T>C (rs794727800, p.

Additional molecular and clinical evidence open the way to definitive IARC classification of the BRCA1 c.5332G > A (p.Asp1778Asn) variant.

Objectives: In silico splicing analysis, a mini-gene assay and splicing data, obtained using RNA from blood samples, have shown that the BRCA1 c.5332G > A variant induces exon 21 skipping. However, despite these evidences, up to date, this variant is unclassified.

High-resolution melting analysis coupled with next-generation sequencing as a simple tool for the identification of a novel somatic BRCA2 variant: a case report.

In a 72-year-old woman with no associated personal or family history of breast and/or ovarian cancers, we identified a novel somatic pathogenic variant (, p.Lys6Asnfs*4) using next-generation sequencing (NGS). The variant allele frequency (VAF) was 16%, and Sanger sequencing was unable to identify this variant.

Report of an Italian family carrying a typical Indian variant of the Nilgiris tribal groups resulting from a occurrence.

G6PD deficiency is quite common in Italy where it is characterized by extreme molecular and biochemical heterogeneity. We report a 15-year-old Italian boy with p.Arg198His), a typical Indian variant of the Nilgiris tribal groups.
