Resumen
Este estudio proporciona las primeras pautas estandarizadas para el asesoramiento genético y las pruebas en ataxia. Las recomendaciones ayudan a los médicos a evaluar a los pacientes con ataxia inexplicable para un diagnóstico y atención oportunos.
Área de la Ciencia:
- Neurogenética
- Medicina genómica
Sus antecedentes:
- Las pruebas genéticas para la ataxia han avanzado significativamente, mejorando el diagnóstico y el tratamiento.
- Actualmente faltan directrices estandarizadas para el asesoramiento y las pruebas genéticas en la ataxia.
Objetivo del estudio:
- Desarrollar recomendaciones basadas en la evidencia para el asesoramiento genético y las pruebas en individuos con ataxia inexplicable.
- Apoyar a los médicos en la evaluación y el tratamiento de los pacientes con ataxia y sus familiares.
Principales métodos:
- Revisión exhaustiva de la literatura de 7362 artículos sobre asesoramiento genético y pruebas en ataxia.
- Selección y filtrado de artículos utilizando el marco EGAPP.
- Convocar un panel multidisciplinario de expertos para las brechas de evidencia y la creación de consenso.
Principales resultados:
- Desarrolló 20 recomendaciones que cubren las indicaciones de las pruebas, el asesoramiento, la interpretación y las derivaciones.
- Enfatizó el asesoramiento genético formal y la secuenciación completa del genoma como pruebas de primera línea.
- Destacó la importancia de detectar expansiones repetidas en la ataxia hereditaria.
Conclusiones:
- Estas recomendaciones proporcionan un marco para que los médicos manejen la ataxia inexplicable.
- Facilita la evaluación genética oportuna y adecuada para los pacientes y los miembros de la familia en riesgo.
- Tiene como objetivo mejorar la precisión del diagnóstico y la atención al paciente en la ataxia hereditaria.

01:59CRISPR
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced Short...
02:59Animal Mitochondrial Genetics
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...
01:16In vitro Mutagenesis
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
02:46Genetic Screens
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which result in visible changes...

01:28Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

01:25Genetic Variation
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
