Overview of Genetic Disorders and Inheritance Patterns

Genetic disorders can be present before birth and produce birth defects, but not all birth defects are hereditary.
Over 6,000 genetic disorders are known, with new ones constantly being described, and more than 600 of them are treatable.
Around 1 in 50 people are affected by a known single-gene disorder, while around 1 in 263 are affected by a chromosomal disorder.
Congenital genetic mutations affect around 65% of people, and approximately 1 in 21 people are affected by a rare genetic disorder.
Genetic disorders can be caused by a mutation in a single gene or multiple genes, or by a chromosomal abnormality.
The mutation responsible can occur spontaneously or be inherited from one or both parents, and some disorders have X-linked or mitochondrial inheritance.
Single-gene disorders can be passed on in several ways, and some disorders have reduced penetrance.
Autosomal dominant disorders only require one mutated gene, while autosomal recessive disorders require two.
X-linked dominant disorders affect males and females, but X-linked recessive disorders affect males more frequently.
Y-linked disorders only affect males and are exceedingly rare.
Mitochondrial disorders are the rarest and only passed on through affected mothers, but most mitochondrial diseases are actually caused by nuclear gene defects.
In vitro fertilization and preimplantation genetic diagnosis can be used to prevent passing on single-gene disorders.
