Síndrome da deleção 2q37.3 – A primeira descrição de achados orais, relato de caso

Introdução: A síndrome de deleção 2q37.3 é uma desordem causada pela microdeleção de uma subbanda no cromossomo 2, cuja epidemiologia é de aproximadamente 150 casos no mundo, e a incidência de 1:10000. As características da síndrome são: atraso no desenvolvimento, dismorfia facial, anormalid...

Improvement of polyhydroxybutyrate production by deletion of csrA in Escherichia coli

BACKGROUND: Poly-3-hydroxybutyrate (PHB) can be efficiently produced in recombinant Escherichia coli by the overexpression of an operon (NphaCAB) encoding PHB synthetase. Strain improvement is considered to be one of critical factors to lower the production cost of PHB in recombinant system. In this stud...

The secreted acid trehalase encoded by the CgATH1 gene is involved in Candida glabrata virulence

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Candida glabrata yeast is the second cause of candidiasis worldwide. Differs from other yeasts since assimilates only glucose and trehalose (a characteristic used in rapid identification tests for this pathogen) by secreting into the medium a highly active acid trehalase encoded by the CgATH1 ...

Role of genetic variability in Mendelian and multifactorial diseases

Gac. méd. Méx; 155 (5), 2019
The first draft of the human genome sequencing published in 2001 reported a large number of single nucleotide polymorphisms (SNPs). Given that these polymorphisms could practically represent all the variability involved in the susceptibility, protection, severity, among other aspects, of various common d...

Searching for mutations in the HNF1B gene in a Brazilian cohort with renal cysts and hyperglycemia

ABSTRACT Objective To verify the presence of variants in HNF1B in a sample of the Brazilian population selected according to the presence of renal cysts associated with hyperglycemia. Subjects and methods We evaluated 28 unrelated patients with clinical suspicion of HNF1B mutation because of the conc...

Síndrome de Rett: Análisis molecular del gen MECP2 en pacientes chilenas

Rev. chil. pediatr; 90 (2), 2019
INTRODUCCIÓN: El síndrome de Rett (RTT) es un trastorno neurológico progresivo caracterizado por producir una regresión del desarrollo psicomotor en niñas previamente sanas. La mayoría de los casos son causados por variantes patogénicas en el gen MECP2, que codifica para la proteína methyl CpG- b...

Análisis de variación del número de copias y de patrones de metilación en la región 15q11-q13
Variation analysis of the number of copies and methylene patterns in region 15q11-q13

Medicina (B.Aires); 78 (1), 2018
La región q11-q13 del cromosoma 15 humano es proclive a sufrir alteraciones genéticas. Algunos genes de la región presentan expresión parental diferencial monoalélica, regulada por imprinting (EI). Errores en la regulación del EI, disomías uniparentales (DSU), así como también el cambio en el nÃ...

The relationship between of ACE I/D and the MTHFR C677T polymorphisms in the pathophysiology of type 2 diabetes mellitus in a population of Brazilian obese patients

ABSTRACT Objectives This study aimed to evaluate the frequencies of the angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) and methylenetetrahydrofolate reductase (MTHFR) gene C677T polymorphisms in obese patients with and without type 2 diabetes mellitus (T2DM). Subjects and methods The...

Angiotensin-Converting Enzyme ID Polymorphism in Patients with Heart Failure Secondary to Chagas Disease

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: Changes in the angiotensin-converting enzyme (ACE) gene may contribute to the increase in blood pressure and consequently to the onset of heart failure (HF). The role of polymorphism is very controversial, and its identification in patients with HF secondary to Chagas disease in the...
