BASES OF HUMAN GENETICS. Human genome organization, genetic markers and DNA polymorphisms, repetitive DNA, physical and genetic maps. Linkage Disequilibrium. Cytogenetics: human chomosomes, normal karyotype, parent-of-origin effects, chromosomal polymorphisms and CNV.
MEDICAL GENETICS. Genetic and hereditary diseases, congenital defects, teratogenesis and mutagenesis. Examples of single-gene diseases. Preparation and interpretation of pedigrees. Modifier genes and complexity in single-gene disorders. Heteroplasmy and mitochondrial diseases.
MEDICAL CYTOGENETICS. Chromosomal abnormalities, numerical and structural. Mosaicism. Chromosomic syndromes and Genome disorders. Uniparental disomy. Uniparental diploidy: hydatiform moles and ovarian teratomas.
DISEASES DUE TO EXPANSION OF UNSTABLE REPEAT SEQUENCES (dynamic mutations). Unstable repeat expansion, premutation and full mutation, Sherman's paradox, anticipation, molecular analysis of repeat expansion.
EPIGENETICS. X chromosome inactivation, DNA metilation, imprinting and diseases due to genomic imprinting defect.
MOLECULAR GENETICS IN MEDICINE. Gene and chromosomal mutations, mutation nomenclature. DNA polymorphisms: RFLP, SNP, VNTR, minisatellites, microsatellites.
