Up-regulation of GINS1 highlighted a good diagnostic and prognostic potential of survival in three different subtypes of human cancer

Braz. j. biol; 84 (), 2024
Abstract Cancer is a fatal malignancy and its increasing worldwide prevalence demands the discovery of more sensitive and reliable molecular biomarkers. To investigate the GINS1 expression level and its prognostic value in distinct human cancers using a series of multi-layered in silico approach may help...

Identification of a rare copy number polymorphic gain at 3q12.2 with candidate genes for familial endometriosis

Abstract Endometriosis is a complex disease that affects 10-15% of women of reproductive age. Familial studies show that relatives of affected patients have a higher risk of developing the disease, implicating a genetic role for this disorder. Little is known about the impact of germline genomic copy num...

Importancia de la determinación de variantes en el número de copias en neonatos con aneuploidías autosómicas

Biomédica (Bogotá); 41 (2), 2021
Resumen | Introducción. Las aneuploidías son trastornos genéticos frecuentes en la práctica clínica; sin embargo, se conoce poco sobre las otras variantes genéticas que modifican el fenotipo final. Objetivo. Determinar las variantes en el número de copias y las regiones con pérdida de heterocigo...

Quantification of mitochondrial DNA damage and copy number in circulating blood of patients with systemic sclerosis by a qPCR-based assay

An. bras. dermatol; 95 (3), 2020
Abstract Background: Although not fully understood, oxidative stress has been implicated in the pathogenesis of different autoimmune diseases such as systemic sclerosis. Accumulating evidence indicates that oxidative stress can induce mitochondrial DNA (mtDNA) damage and variations in mtDNA copy number ...

Minor temperature shifts do not affect chromosomal ploidy but cause transcriptomic changes in Leishmania braziliensis promastigotes in vitro

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND The leishmaniases are complex neglected diseases caused by protozoan parasites of the genus Leishmania. Leishmania braziliensis is the main etiological agent of cutaneous leishmaniasis in the New World. In recent studies, genomic changes such as chromosome and gene copy number variations (CNV...

The study of copy number variations in the regions of PRKAB2 and PPM1K among congenital heart defects patients

SUMMARY OBJECTIVE: This study was to assess the genetic association of copy number variations in two genes (PRKAB2 and PPM1K) located in two regions (tetralogy of Fallot and ventricular septal defect) in a Chinese Han population. METHODS: A total of 200 congenital heart disease patients (100 tetralogy ...

Impact of C4, C4A and C4B gene copy number variation in the susceptibility, phenotype and progression of systemic lupus erythematosus

Adv Rheumatol; 59 (), 2019
Abstract Background Complement component 4 (C4) gene copy number (GCN) affects the susceptibility to systemic lupus erythematosus (SLE) in different populations, however the possible phenotype significance remains to be determined. This study aimed to associate C4A , C4B and total C4 GCN and SLE, focusi...

Variação de número de cópias no cromossomo 4: uma possível síndrome genética?

Rev. bras. neurol; 54 (4), 2018
INTRODUÇÃO: Variantes de número de cópias (CNVs) são variações no número de cópias de uma região da sequência genômica, descrevendo deleções ou ganhos em relação a indivíduos controle. Podem ser comuns e de caráter benigno, de significado incerto ou variantes patogênicas. Para interpre...

Clinical and mutational spectrum of Colombian patients with Pelizaeus Merzbacher Disease

Colomb. med; 49 (2), 2018
Abstract Case Presentation: Pelizaeus Merzbacher Disease (PMD) is an X-linked developmental defect of myelination that causes childhood chronic spastic encephalopathy. Its genetic etiology can be either a duplication (or other gene dosage alterations) or a punctual mutation at the PLP1 locus. Clinically...

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 n�...
