Learning objectives
To give the bases for the understanding of the main disorders with a genetic, genomic or chromosomal basis with a pediatric onset
Prerequisites
Preliminary knowledge of:
• DNA structure and replication
• Chromosome structure and human karyotype
• Gene structure, transcription and maturation of the mRNA.
• Protein structure. Structure and function of the enzymes
• Phenotypic variation at the cellular, tissue and individual level
• Genetic polymorphisms
• Mendelian inheritance in man
• Principles of population genetics
• Mutations as cause of variability
• Gene mutations. Types, location and genetic analysis
• Molecular mechanisms of the genetic mutations and their consequences for the synthesis and structure of the proteins
• Chromosomal aneuploidies and their pathogenetic mechanism
