Resumen
Las variantes bialélicas de la UDP-glucosa deshidrogenasa (UGDH) causan encefalopatía del desarrollo y epilepsia (DEE). Esta revisión detalla las mutaciones de UGDH
Área de la Ciencia:
- La bioquímica
- La genética
- Biología del desarrollo
Sus antecedentes:
- Los trastornos congénitos de la glucosilación son una causa clave de la encefalopatía del desarrollo y la epilepsia.
- Las variantes bialélicas en el gen UDP-glucosa deshidrogenasa (UGDH) son una causa genética específica de la DEE.
- La UGDH es esencial para la síntesis de glucuronato UDP, crucial para el hialuronano, los proteoglicanos y la desintoxicación.
Objetivo del estudio:
- Revisar los efectos clínicos y moleculares de las variantes de la UGDH.
- Para resumir el papel de UGDH en los trastornos congénitos.
- Para discutir los defectos de desarrollo relacionados con la UGDH.
Principales métodos:
- Revisión de la literatura sobre las variantes de la UGDH y los fenotipos asociados.
- Análisis de la función de la enzima UGDH y sus vías bioquímicas.
- Correlación de las mutaciones genéticas con las manifestaciones clínicas.
Principales resultados:
- Las variantes de UGDH conducen a defectos congénitos en el desarrollo de la válvula cardíaca y el cerebro.
- Las mutaciones en la UGDH están relacionadas con la distroglicanopatía.
- Los polimorfismos dañinos de la UGDH son raros pero significativos.
Conclusiones:
- Las variantes UGDH representan una causa genética específica de DEE y trastornos del desarrollo.
- Comprender el impacto molecular de la UGDH es crucial para diagnosticar y potencialmente tratar estas afecciones.
- Las investigaciones adicionales sobre la función de la UGDH pueden dilucidar vías complejas de desarrollo.

Human 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.

Animal Mitochondrial Genetics
8.0K
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...

Genomic Imprinting and Inheritance
35.2K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Incomplete Dominance
25.4K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Genome-wide Association Studies-GWAS
14.1K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
