Identificación del alelo HLA B*57: 01 en una población militar, de Lima-Perú

Rev. chil. infectol; 41 (2), 2024
El alelo HLA B*57:01 es un marcador genético asociado con la hipersensibilidad al fármaco anti-retroviral abacavir (ABC) y su frecuencia en la población peruana todavía es desconocida. El objetivo fue identificar el alelo HLA B*57:01 en una población militar de Lima, Perú. Se reclutaron 43 personas...

New candidate SNPs for genetic association with Alzheimer’s disease: a linkage disequilibrium analysis for the FCGRIIB and PILRA genes

Medwave; 24 (1), 2024
BACKGROUND: Two new SNPs have been recently associated to Alzheimer’s disease in African American populations: FCGRIIB rs1050501 C/T, and PILRA rs1859788 A/G. The risk of Alzheimer’s disease in FCGRIIB C and PILRA A allele carriers is three times higher than in non-carriers. However, the association ...

The influence of germline mutations on breast cancer

Mastology (Online); 34 (), 2024
The ability to evade protection mechanisms and uncontrolled cell growth can lead to the development of mutations, whether somatic or germline, and consequently to the dreaded diagnosis of cancer. Breast cancer is considered the most common type of cancer in women in several regions of Brazil, mainly in t...

Menopausia quirúrgica en pacientes con mutación BRCA, el papel de la terapia hormonal
Surgical Menopause in Patients with BRCA Mutation, the Role of Hormone Therapy

Introducción: las mujeres con mutación BRCA1/2 (mBRCA) tienen un riesgo aumentado de desarrollar cáncer de mama (CM) y ovario (CO). La salpingo-oforectomía bilateral (SOB) se asocia con la reducción del riesgo del 80% para CO y un 50% para CM. Se recomienda realizarla entre los 35...

Efecto del sedentarismo sobre la interacción entre el gen FTO y niveles de adiposidad en adultos chilenos - Resultados del Estudio GENADIO

Rev. méd. Chile; 151 (8), 2023
ANTECEDENTES: Tanto el gen FTO (Fat-mass and obesity-associated-gene) y el tiempo sedente se asocian a obesidad, sin embargo, se desconoce si el tiempo sedente puede modificar la predisposición genética a la obesidad. Por ende, el objetivo de este estudio fue investigar si la asociación entre el polim...

Toll-like receptor 9 polymorphisms in brazilian patients with systemic lupus erythematosus: a pilot study

Braz. j. biol; 83 (), 2023
Abstract Toll-like receptor 9 (TLR9) is an important component of the innate immune system and have been associated with several autoimmune diseases, such as Systemic Lupus Erythematosus (SLE). The aim of this study was to investigate polymorphisms in TLR9 gene in a Brazilian SLE patients group and their...

Genetic variability in the neurobiology of nicotine dependence: effects on smoking behavior

Abstract Background Smoking dependence is a chronic disease and a public health problem. The neurobiology of nicotine addiction can explain smoking behavior. This system has genetic variability that has been associated with vulnerability to dependence. Genetic variability in the neurobiology of smoking ...

Reporte de caso de feocromocitoma bilateral asociado a mutación del gen TMEM127. Primer caso chileno

Rev. med. Chile; 150 (8), 2022
Up to 40% of Pheochromocytoma/paraganglioma syndromes are associated with germline mutations. Therefore, they are considered familial and heritable. We report a 65 year old woman with hypertension, bilateral adrenal nodules found in the CT scan and elevated urinary metanephrines. Her genetic testing show...

Genes humanos asociados a la infección por el SARS-CoV-2
Human genes associated with SARS-CoV-2 infection

Gac. méd. espirit; 24 (1), 2022
RESUMEN Fundamento: La variabilidad clínica de la infección por el SARS-CoV-2 se debe, en parte, a factores genéticos. Objetivo: Describir los principales genes de susceptibilidad a la Covid-19. Metodología: Se realizó una revisión bibliográfica en Google Académico, SciELO, Annual Reviews y PubMe...

The A allele of the rs759853 single nucleotide polymorphism in the AKR1B1 gene confers risk for diabetic kidney disease in patients with type 2 diabetes from a Brazilian population

ABSTRACT Objective: The AKR1B1 gene encodes an enzyme that catalyzes the reduction of glucose into sorbitol. Chronic hyperglycemia in patients with diabetes mellitus (DM) leads to increased AKR1B1 affinity for glucose and, consequently, sorbitol accumulation. Elevated sorbitol increases oxidative stress...
