Non-Mendelian Inheritance


   Lesson 1: Triplet Repeat Disorders
   Lesson 2: Genomic Imprinting
   Lesson 3: Mosaicism
   Lesson 4: Mitochondrial Mutations

This course covers the pattern of non-Mendelian inheritance. After completing it, you will have a basic understanding of:

  • Features of triplet repeat disorders and their inheritance
  • Genomic imprinting and uniparental disomy and their clinical consequences
  • Germline and somatic mosaicism
  • Mitochondrial DNA mutations, their inheritance, and possible clinical symptoms
