Mucopolysaccharidosis type I (MPS-I) is an autosomal recessive lysosomal storage disorder caused by a deficiency or absence of α--iduronidase, which is involved in the catabolism of glycosaminoglycans (GAGs). This deficiency leads to the accumulation of GAGs in several organs. Given the wide spectrum of the disease, MPS-I has historically been classified into 3 clinical subtypes - severe ( ... more

Chinese soft-shelled turtle Pelodiscus sinensis has been an important aquaculture species in Southeast Asian countries. To breed a new variety of soft-shelled turtle with excellent properties and to evaluate the effect of hybridization of two turtle strains with a highly different trait phenotype, inheritance, microsatellite loci, and transcriptome analysis were studied in the hybrid turtles ... more

The coronary arteriosclerotic disease is the most common cardiovascular disease. Atherosclerosis affects large- and medium-sized arteries leading to severe thrombosis or artery stenosis that could evolve to myocardial infarction, ischemic stroke, ischemic injury of kidneys and intestines, and several other life-threatening clinical manifestations. Nitric oxide has been shown to be a promising ... more

Type 1 diabetes (T1D) is an autoimmune disease with a strong genetic component that has been associated with several genetic loci. Interleukin 18 (IL-18) is a potent proinflammatory cytokine, which is involved in the innate and adaptive immune responses, and in the pathogenesis of various diseases including T1D. Glucose transporter 4 (GLUT4) is known to be an insulin-responsive glucose ... more

Acute coronary syndrome; Aged; Case-control studies; Female; Genotype; Heterozygote; Humans; male; Mexico; Middle Aged; Peptidyl-Dipeptidase A; Polymorphism, Single Nucleotide

Acute coronary syndrome (ACS) is considered one of the main causes of death worldwide. Contradictory findings concerning the impact of the angiotensin-converting enzyme (ACE) gene on cardiovascular diseases have been reported. Previous conclusions point out that the variability in results depends on ethnicity and genetic polymorphisms to determine the association of rs4340 polymorphisms of the ... more

Double aneuploidy is considered a rare phenomenon. Herein, we describe a case of double aneuploidy 48,XXY,+21 in a neonate with congenital heart defects. The 28-day-old neonate male (23-year-old mother and 24-year-old father) was admitted to a neonatal intensive care unit owing to congenital heart disease. Echocardiography showed a complete atrioventricular septal defect with Rastelli type B ... more

Complementary and alternative therapies, including the use of medicinal plants, have become almost standard among the world's population. Pfaffia glomerata (PG), popularly known as Brazilian ginseng, is widely used as a restorer of vital functions, increasing mental balance, and is used for the treatment of diabetes and rheumatism. Ginkgo biloba (GB) is one of the oldest known gymnosperms, ... more

Gene; Mutation; TSC1; Tuberous sclerosis complex

Tuberous sclerosis complex is an autosomal-dominant heritable disease caused by mutations in the TSC1 and TSC2 genes. We studied a Chinese patient with sporadic tuberous sclerosis complex. The clinical features of this patient included epilepsy, hypomelanotic macules and angiofibromas on his back; a cranial CT scan showed subependymal nodules along the lateral walls of the ... more

Biomarker; Mutation; Myelodysplastic syndromes; Refractory cytopenias with multilineage dysplasia; TET2

Myelodysplastic syndrome diagnosis of karyotypically normal patients may be elusive because it relies exclusively on morphological and clinical data. In routine practice, finding of an acquired mutation or a cytogenetic abnormality provides irrefutable evidence of the clonal nature of that disease. Recurrent deletions and somatic mutations in TET2, a gene involved in epigenetic ... more

Charcot-Marie-Tooth; Gender; Mitofusin 2; Mutation

Charcot-Marie-Tooth (CMT) is a group of clinically and genetically heterogeneous inherited neuromuscular disorders. At present, more than 30 loci have been reported to be associated with CMT disease; point mutations in the mitofusin 2 (MFN2) gene is one of the most common causes. We studied a Chinese family with CMT disease in which the phenotype of affected individuals varied, and the ... more
