1. Genetic-molecular characterization in the diagnosis of primary immunodeficiencies
Abstract Objectives: To rescue medical genetics concepts that are necessary to understand the advances in the genetic-molecular characterization of primary immunodeficiencies, to help in the understanding and adequate interpretation of their results. Source of data: Non-systematic literature review, searching for articles since 2000 on PubMed using the ter

2. An intricate case of sporadic pseudohypoparathyroidism type 1B with a review of literature
SUMMARY Pseudohypoparathyroidism comprehends an assorted group of genetically rare disorders that share end-organ resistance to parathyroid hormone. Genetic and epigenetic modifications on guanine nucleotide-binding protein alpha-stimulating gene locus are the most common underlying mechanisms associated with pseudohypoparathyroidism. Biochemical and molecul

4. Leigh Syndrome Due to mtDNA Pathogenic Variants
Abstract Leigh syndrome is a devastating neurodegenerative disease, typically manifesting in infancy or early childhood. Hallmarks of the disease are symmetrical lesions in the basal ganglia or brain stem on MRI, and a clinical course with rapid deterioration of cognitive and motor functions. It is genetically heterogeneous, causative mutations have been dis

6. Combined pituitary hormone deficiency caused by PROP1 mutations: update 20 years post-discovery
ABSTRACT The first description of patients with combined pituitary hormone deficiencies (CPHD) caused by PROP1 mutations was made 20 years ago. Here we updated the clinical and genetic characteristics of patients with PROP1 mutations and summarized the phenotypes of 14 patients with 7 different pathogenic PROP1 mutations followed at the Hospital das Clínica

7. Lysosomal diseases: Overview on current diagnosis and treatment
Abstract Lysosomal diseases (LDs), also known as lysosomal storage diseases (LSDs), are a heterogeneous group of conditions caused by defects in lysosomal function. LDs may result from deficiency of lysosomal hydrolases, membrane-associated transporters or other non-enzymatic proteins. Interest in the LD field is growing each year, as more conditions are, or

8. Mutation Spectrum and Genotype–Phenotype Correlation in a Cohort of Argentine Patients with Ornithine Transcarbamylase Deficiency: A Single-Center Experience
Abstract X-linked ornithine transcarbamylase deficiency (OTCD) is the most common urea cycle disorder. Hemizygous males with complete deficiency manifest neonatal acute hyperammonemia, while those with partial deficiency have a late presentation. The symptomatology of heterozygotes depends on the inactivation pattern of X chromosome. Hyperammonemic episodes

10. Novel mutations associated with pyruvate kinase deficiency in Brazil
Abstract Background: Pyruvate kinase deficiency is a hereditary disease that affects the glycolytic pathway of the red blood cell, causing nonspherocytic hemolytic anemia. The disease is transmitted as an autosomal recessive trait and shows a marked variability in clinical expression. This study reports on the molecular characterization of ten Brazilian pyr

11. Rare α0-thalassemia deletions detected by MLPA in five unrelated Brazilian patients
Abstract Alpha-thalassemias are among the most common genetic diseases in the world. They are characterized by hypochromic and microcytic anemia and great clinical variability, ranging from a practically asymptomatic phenotype to severe anemia, which can lead to intrauterine or early neonatal death. Deletions affecting the α-globin genes, located on chromos

12. Determining mutations in G6PC and SLC37A4 genes in a sample of Brazilian patients with glycogen storage disease types Ia and Ib
Glycogen storage disease (GSD) comprises a group of autosomal recessive disorders characterized by deficiency of the enzymes that regulate the synthesis or degradation of glycogen. Types Ia and Ib are the most prevalent; while the former is caused by deficiency of glucose-6-phosphatase (G6Pase), the latter is associated with impaired glucose-6-phosphate tran
